Making first call
Once you acquire your project_id token, let's give the API a try! You need to pass this it as an HTTP header with the name project_id. Don't forget that you can call just the network you created the token for.
info
Each network has separate project_id tokens, distinguishable by the prefix.
In this example, we set project_id as an environment variable and then use it to call the API. Don't forget to replace the PROJECT_ID in the example with your newly generated one!
