Today, we’re talking about something that has been a mystery to me for quite some time. We are talking about APIs and how to get data from them using R. And we will do that with the help of the {httr2} package. This is quite a broad topic so this will be quite a long ride. Here’s our playbook for today:

Level 1 (easy): We dip our toes into the water and learn what an API is and how to make a request to an API. At this stage we’re just getting data from the US National Weather Service which does not require any authentication. Authentication can be a pain in the ass, so we that’s why this is the easy level.
Level 2 (intermediate): In Level 1 we hit the API of the weather service to get the weather data at a specific coordinate. But what if we want to get the weather forecast for an address? That’s where Google’s geocoding API comes in. It gives us coordinates to addresses that we pass to it. But this API requires authentication.
Level 3 (intermediate): Another form of authentication uses Bearer tokens. It’s very similar to what we already learned in Level 2. So that’s why it’s not a huge step up. But still it’s good to see how that one works. One particular example for that is OpenAI’s API. We’re going to use it to have a chat with ChatGPT from R.
Level 4 (hard): I already said that authentication can be a pain in the ass. In particular, the YouTube API is hard to navigate because it uses something called OAuth 2.0 authentication. This one is quite a complicated construct but {httr2} helps us here too. I’ll show you how that works.

So that’s our gameplay for this blog post. As I’ve said, this one will be a long one. Hence the name “Ultimate Guide”. But if you want to lean back and enjoy all of this content in video form, I’ve got you covered. You can find the video version of this blog post on my YouTube channel:

Level 1: Getting to know APIs

Alright, Level 1 is doing small steps with APIs. Let’s dive in.

What is an API?

API stands for Application Programming Interface. Broadly speaking, an API is anything that we can throw code at to get results that we want. Often, this refers to some data source that we tap into. But sometimes it also simply means the syntax of code. For example, ggplot2 has a very distinctive API, i.e. a code syntax to create a chart. In this blog post, though, we will just refer to APIs as data sources.

Making requests to an API

If you’ve never worked with APIs, you know that it can feel like data is hidden away behind an API. Thankfully, the {httr2} package helps us a lot, even if we’ve never dealt with APIs before. This package allows us to use a step-by-step workflow that is always the same. Here’s how it looks and don’t worry if this doesn’t mean a thing to you yet:

1️⃣ Stick a base URL it into request().

2️⃣ Pipe that request into all kinds of req_*() functions to fill your request with the parameters and authentication your request needs.

3️⃣ Perform your request after your filled in all the parameters you need with req_perform().

4️⃣ Extract the data from the response via resp_body_json() to turn the JSON response into a list.

So these are the steps that make up an API request to get data. And the cool thing is: With the US National Weather Service we can do that manually first to understand what’s going on. Just head to the following url using your web browser:

https://api.weather.gov/points/38.8894,-77.0352

If you navigate there, you will get cryptic data like that:

This is what is known as a JSON file. More on that later. For now, notice that what you see at the end of the url after points/ corresponds to the coordinates that are given in the JSON output. (Compare that with the things the red arrow is pointing at)

This means that the recipe for calling the weather API is simple: Append points/{lat},{long} at the end of the base_url, i.e. https://api.weather.gov/. In this case, {lat},{long} corresponds to the latitude and longitude of the location you want to get weather forecasts for.

Making a request with {httr2}

The {httr2} syntax to make this work mimics this quite well. Here’s how it looks.

library(httr2)
NWS_base_url <- 'https://api.weather.gov'
request(NWS_base_url) |> 
  req_url_path_append(
    'points',
    '38.8894,-77.0352'
  ) 
## <httr2_request>
## GET https://api.weather.gov/points/38.8894,-77.0352
## Body: empty

Basically, at the core of every request is the request() function that needs to know the base_url. This returns an <httr2_request> object that can be passed to further req_*() functions to modify the request.

Here, we used req_url_path_append() to modify the request but there are also other functions. We’ll learn a couple more soon enough. Finally, to actually make the request, you can pass everything to req_perform().

library(httr2)
NWS_base_url <- 'https://api.weather.gov'
NWS_response <- request(NWS_base_url) |> 
  req_url_path_append(
    'points',
    '38.8894,-77.0352'
  ) |> 
  req_perform()
NWS_response
## <httr2_response>
## GET https://api.weather.gov/points/38.8894,-77.0352
## Status: 200 OK
## Content-Type: application/geo+json
## Body: In memory (3091 bytes)

Understanding the response

As you’ve just seen, your request will return a <httr2_response> and if everything went well, the output will also show you Status: 200 OK. You can get the actual content (the JSON that you’ve seen in your web browser earlier) via one of the many resp_*() functions that handle responses. This will give you a highly nested list (which is why the output looks so huge.)

Working with the response

To make sense of this highly nested list, we use glimpse() to understand the structure of the object.

And with pluck() you can easily drill down into specific parts of the list. For example, this could be used to get the URL for the hourly forecasts.

forecast_url <- NWS_response |> 
  resp_body_json() |> 
  pluck('properties', 'forecastHourly')
forecast_url
## [1] "https://api.weather.gov/gridpoints/LWX/97,71/forecast/hourly"

Repeat process for forecasts

With the new forecast URL, we can get new JSON data about the forecasts for our location.

forecast_response <- request(forecast_url) |> 
  req_perform()

In that output, we can see that there is a list called periods inside of the properties list. This periods lists contains more lists which always have 16 entries. This might be where our forecast data lives.

Aha! Each of those 16-entries lists seem to correspond to the forecast of one hour. Thus, to get the things like temperature, startTime, probabilityOfPrecipitation, and short_forecast into a nice tibble format, we have to iterate over all of these 16-entries lists and wrap the values we want into a tibble.

extracted_data <- forecast_response |> 
  resp_body_json() |> 
  pluck('properties', 'periods') |> 
  map_dfr( # iterates over each list and binds rows to a tibble
    \(x) {
      tibble(
        time = x |> pluck('startTime'),
        temp_F = x |> pluck('temperature'),
        rain_prob = x |> pluck('probabilityOfPrecipitation', 'value'),
        forecast = x |> pluck('shortForecast')
      )
    }
  )
extracted_data
## # A tibble: 156 × 4

And once we have that data, we can transform the time column into a nice date-time object:

  mutate(

Nice! We have successfully hit the API of the National Weather Service. Level 1, check!

Level 2: Authenticating with API Keys

To get the weather forecast, we had to know the coordinates of the location we want to check the weather for. So this begs the question: How do we get coordinates in the first place?

This requires hitting the API of a geocoding service like the one from Google Maps. Unfortunately for us, Google requires us to make an authenticated call. Thus, calling the API becomes a bit more tricky.

Creating a Geocode API

Essentially what we want to do now is to send addresses like “1900 E Kenwood Blvd, Milwaukee, WI 53211, USA” to Google and get coordinates back. (Fun fact: this address refers to the Physics building of UW-Milwaukee where many of the math TAs have their office. At least it was like that when I was a math TA there.)

If you look at the Get Started Page of Google’s geocoding API, you will find a URL that looks like this:

https://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&key=

If you inspect this closely, you will find

a question mark ? followed by
address=,
some stuff that looks like the address “1600 Amphitheatre Parkway, Mountain View, CA” encoded into a URL, and
key=

And if you follow the link you will get an error message like this:

Authenticate!

Aha! The video game player in me has found enough evidence that tells me that we must find a key that we can fit into key=. And just like in a video game, this might entail a whole different quest first.

In this case, we will have to take a good look at the getting started guide again (get used to reading API docs to find out how to operate them 😭). This will reveal a crucial hint:

So I guess we follow the link into the Cloud Console which leads us into yet another doc page:

So we follow the big blue button and do all the steps to create a new project. Unfortunately, this will require us to also put in some billing information and we cannot get around that. Don’t worry: The geocoding service has a generous free tier and you will not actually get billed until you manually upgrade to a paid tier.

A project is nothing without an API

Nice, we’ve set up a new Google project. Inside of these projects we can use different APIs such as the geocoding API. The easiest way to enable that for our project is to follow the big blue button from the docs:

This is where we can acquire an API key for our project and for security we can enable that the geocoding API shall be the only API the key can unlock.

Once that is done, you’re on your project dashboard and you can head to the Credentials page. There, the “Show Key” link will lead you to your API key.

API Key Security

I’m not a security expert but here’s a word of caution for you: ⚠️ DO NOT SHARE YOUR API KEY WITH ANYONE. ⚠️

This includes not putting your API code into your R script or any other type of script. Why? Because you might want to put your code into a public repo on GitHub long after you have forgotten that you put your API key in a script file.

Same thing goes for the R console. You might share your console history as part of a repo by accident. Then, someone could just look up your API key in your R console history.

So what to do instead? It’s simple really. It’s called using “environment variables”. Usually, what you do is store an .env file (the dot is important) inside your project repository. (Put that file into .gitignore immediately!)

With dotenv::load_dot_env() you can then enable access to your .env file such that Sys.getenv('<Variable_name>') can access your API key. For example, if your API-key is 123, you could store API KEYS in the .env file as

GEOCODE_API_KEY=123
SOME_OTHER_KEY=34653462542

Then, Sys.getenv('GEOCODE_API_KEY') would return the API key 123. But you don’t want to execute this code directly! What you want to do instead is use that inside of functions that need the API key like this one here:

library(tidyverse)
library(httr2)
dotenv::load_dot_env()

geocode_base_url <- 'https://maps.googleapis.com/maps/api/geocode/json'
response <- request(geocode_base_url) |> 
  req_url_query(
    address = '1900 E Kenwood Blvd, Milwaukee, WI 53211, USA',
    key = Sys.getenv('GEOCODE_API_KEY')
  ) |>
  req_perform()

Using query parameters

This code uses the URL that we have seen earlier. You know, the one that was followed by a ?, address=... and key.... In this scenario, everything that comes before the ? is the base URL for our API call. And everything after the question mark is the query to the API.

As we know, this query need to have an address and a key. Luckily for us, {httr2} makes it easy to append that stuff to the URL via req_url_query(). Once the new URL is assembled, we just have to perform the request.

Getting the coordinates

Now, we can evaluate our API response just like we learned on Level 1. Here’s how it looks.

response |> 
  resp_body_json() |> 
  glimpse()
## List of 2
##  $ results:List of 1
##   ..$ :List of 5
##   .. ..$ address_components:List of 10
##   .. ..$ formatted_address : chr "Physics Bldg, 1900 E Kenwood Blvd, Milwaukee, WI 53211, USA"
##   .. ..$ geometry          :List of 4
##   .. ..$ place_id          : chr "ChIJyWzLWNIYBYgRfK6Wf4sFUjg"
##   .. ..$ types             :List of 1
##  $ status : chr "OK"

And by drilling down into the right parts with pluck() we find our desired coordinates:

response |> 
  resp_body_json() |> 
  pluck('results', 1, 'geometry', 'location')  |> 
  unlist()
##       lat       lng 
##  43.07515 -87.88608

Hooray! We can now find the coordinates for any address in the US.

Level 3: Authentication with Bearer Token in Headers

On to Level 3, my friends. On this level, we are going to call OpenAI’s API. In the API reference, you can find an example API request that uses curl. Here’s how it looks:

curl https://api.openai.com/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $OPENAI_API_KEY" \
  -d '{
     "model": "gpt-3.5-turbo",
     "messages": [{"role": "user", "content": "Say this is a test!"}],
     "temperature": 0.7
   }'

curl is a very popular command-line tool that can make requests to APIs. That’s why it’s common to find common curl request examples in the docs of APIs. And that’s also why the {httr2} package has a nice translate function for that. For example, here are some demos from the docs.

curl_translate("curl http://example.com -X DELETE")
## request("http://example.com") |> 
##   req_method("DELETE") |> 
##   req_perform()
curl_translate("curl http://example.com --header A:1 --header B:2")
## request("http://example.com") |> 
##   req_headers(
##     A = "1",
##     B = "2",
##   ) |> 
##   req_perform()
curl_translate("curl http://example.com --verbose")
## request("http://example.com") |> 
##   req_perform(verbosity = 1)

Build headers

Unfortunately, curl_translate() doesn’t seem to work for our example from openAI. So I guess we will have to thing about this after all. But the good hing is that the examples already give us most of what we need. You see, in the example that includes --header we can see that the function req_headers() was necessary. And since -H and --header are the same thing, we can translate the header part already.

oai_completions_url <- 'https://api.openai.com/v1/chat/completions'
request(oai_completions_url) |> 
  req_headers(
    'Content-Type' = 'application/json',
    Authorization  =  'Bearer $OPENAI_API_KEY'
  )

Build body

Next, we can see that the curl example includes data (-d) that is passed to it via JSON. The tell-tale sign was the { }. And if you go through the req_*() function you will notice that there is a function that has json in its name. That’s the one we’ll need.

request(oai_completions_url) |> 
  req_headers(
    'Content-Type' = 'application/json',
    Authorization  =  'Bearer $OPENAI_API_KEY'
  ) |> 
  req_body_json(
    data = list(
      model = "gpt-3.5-turbo",
      messages = list(
        role = 'user',
        content = "Say this is a test!"
      ),
      temperature = 0.7
    )
  )

All we have to do now is to replace $OPENAI_API_KEY with an API key. You can generate one for yourself via OpenAI’s platform. Once that is done, we can modify our code and make a request. Beware though that this will incur costs as you pay for using OpenAI’s API. And to make this more interesting, I’ve replaced “Say this is a test!” with something more on topic.

# Reload .env-file after including new key
dotenv::load_dot_env()
oai_response <- request(oai_completions_url) |> 
  req_headers(
    'Content-Type' = 'application/json',
    Authorization  =  glue::glue(
      'Bearer {Sys.getenv("OAI_HTTR_TUTORIAL")}'
    )
  ) |> 
  req_body_json(
    data = list(
      model = "gpt-3.5-turbo",
      messages = list(
        list(
          role = 'user',
          content = "What's {httr2} in the programming language R?"
        )
      ),
      temperature = 0.7
    )
  ) |> 
  req_perform()

In the response, you can see how many tokens this chat completion cost. You can find the costs per 1000 tokens on OpenAi’s Pricing page.

Nice, that’s a decent answer. Three levels down, one more level to go.

Level 4: OAuth2.0 Authenticaton

Finally, let’s figure out how to handle OAuth2.0 authentication. This style of authenticating is everywhere on the web and it used to be a mystery to me. So on this levle we untangle the necessary steps for OAuth and get viewing stats via the YouTube API.

What the heck is OAuth2.0?

Authentication is a bit of mystery if you don’t take a deep dive into that topic. It always starts out innocent with an API key. And all of a sudden you need some sort of secret handshake here, two ounces of a virgin’s blood there, wait 1.25 full moon cycles and you’re authenticated. It’s a bit of a mess.

So with that said, let’s not make it more complicated than it needs to be. At the end of the day, OAuth is a way to authenticate a user without giving away their password.

This involves a lot of back and forth between the user, the app and the server. And the main ingredients in this procedure are:

An OAuth client
A URL with information about the scopes (permissions) needed
A URL to make the authentication requests to.

The latter two things are usually provided by the API docs and the first one is something you have to set up yourself.

Set up the OAuth client

In our case, we want to get viewing stats of a particular video from the YouTube API. So we need to set up an OAuth client for the YouTube API. This requires first enabling the YouTube API in the Google Cloud Console. We can use the same project from Level 2 and just enable the YouTube API.

There, we enable the additional YouTube Data API v3. Just hit the “Enable APIs and services” button and look for that API. Once you’ve enabled that API, you are required to set up the “OAuth consent screen”. You can leave most of the settings blank and just hit “Save and continue”. The only thing you need to do is to

set the client to “External” and
add your Googlemail as a test user.

Back on the YouTube Data API v3 page, you can create credentials. Make sure to create an OAuth client.

There, you will have to

set the application type to “Web application”,
add a name and
add the redirect URI. This one is important and we’ll come back to that later. Just put this to http://localhost:7094 for now. (You could change the number in the URL to any number you like.)

Once you’ve created the OAuth client, you will get a notification that everything was set up successfully. There, you should download the credentials as JSON. This one will contain all the information we need to set up the client with {httr2}.

Set up the OAuth client with {httr2}

Now we need to make sure that {httr2} can operate that client for us. This is done by using the oauth_client() function. We will need to provide the client ID, the token URL and the client secret. All of these information can be extracted from the JSON file you just downloaded (Open the JSON file with any text editor for that).

# Reload environment after adding ID and secret to .env
dotenv::load_dot_env('.env')
YT_oauth_client <- oauth_client(
  id = Sys.getenv('YT_OAuth_id_tutorial'),
  token_url = 'https://oauth2.googleapis.com/token',
  secret = Sys.getenv('YT_OAuth_secret_tutorial')
)

Set up the YT request

Nice, we have an OAuth client set up. Time to make a request to the YouTube API to get the stats of a YouTube video. I would use my own video for that but I want to make sure that I indeed access the public information of a YT video. That way, you can use the same code and get the same results.

So let’s use one of Ali Abdaal’s videos. We can get the video ID from the URL of the video.

video_id <- 'hXP5fUfBGQQ'

Then, to find out what parameters we can use to get the stats of a video, we need to consult the API docs. First thing they tell us is the URL we need to make the request to.

YT_data_URL <- 'https://www.googleapis.com/youtube/v3/videos'

And the other thing we need to know is the parameters we can use. Here, we will use

the part parameter to specify the information we want to get and
the id parameter to specify the video we want to get the information for.

request(YT_data_URL) |> 
  req_url_query(
    part = 'statistics',
    id = video_id
  )

Authenticate the request

Now that we have the request set up, we need to stick in the OAuth part in there. All we have to do is to pipe our current {httr2} chain into the function that handles the OAuth part.

YT_req <- request(YT_data_URL) |> 
  req_url_query(
    part = 'statistics',
    id = video_id
  ) |> 
  req_oauth_auth_code(
    client    = YT_oauth_client,
    scope     = 'https://www.googleapis.com/auth/youtube.readonly',
    auth_url  = 'https://accounts.google.com/o/oauth2/auth',
    port      = 7094
  ) |> 
  req_perform()

As you can see, we used the req_oauth_auth_code() function to authenticate the request. This function takes

the OAuth client we set up earlier,
the scope of the request (the permissions we need),
the URL to make the authentication requests to, and
the port we want to use for the authentication.

And you’re probably wondering where I got the correct values from. Here’s how I knew what to put in there:

Scope: Search for the word *“scopes”** inside of the API docs and you’ll get a list of all the scopes you can use.
Authentication URL: It’s in the docs as well but conveniently it’s also in the JSON file we downloaded.
Port: This is the number we used in the URI redirect when we set up the OAuth client inside of the Google Cloud Console.

In any case, this code now works. When we execute it, our browser will open and ask us to authenticate the request. Once we do that with our Google account, the code will continue to run and we will get the data from the YouTube API. Hooray!

Get the data

Now that we got the data from YT, we can access the returned data just like we learned in the previous levels.

YT_req |> 
  resp_body_json() |> 
  purrr::pluck('items', 1, 'statistics')
# $viewCount
# [1] "1439580"
# 
# $likeCount
# [1] "39190"
# 
# $favoriteCount
# [1] "0"
# 
# $commentCount
# [1] "667"

Looks like Ali got 1.4 million views and 40k likes on that video. Good for him. Make sure to like and view all of my videos so that my videos can keep up 🤣

Cache the keys

Now before I’ll let you scoot off to watch tons of my videos (I’m sure you’re motivated to do that now), I want to show you how to cache the keys. You see, {httr2} is so kind to cache the keys for you. This means you don’t have to authenticate every time you make a request.

But what if you clicked on the wrong account when your web browser opened up? That’s actually what happened to me. I thought my code was wrong as I got an “Access denied” error. But it was just that I authenticated with the wrong account. And due to the caching, I couldn’t authenticate again.

The way to solve that problem, is to specify a name under which your authentication should be cached. If you authenticated with the wrong account, just use a different name and you can authenticate again.

YT_req <- request(YT_data_URL) |> 
  req_url_query(
    part = 'statistics',
    id = video_id
  ) |> 
  req_oauth_auth_code(
    client    = YT_oauth_client,
    scope     = 'https://www.googleapis.com/auth/youtube.readonly',
    auth_url  = 'https://accounts.google.com/o/oauth2/auth',
    port      = 7094,
    cache_key = 'YT_tutorial'
  ) |> 
  req_perform()
