Request Callout: Request a token and insert it in a request - Plugin

Request a token and insert it in a requestv3.10+

Configure the Request Callout plugin to:

Send a request to an API to get a token
Use the token in the request to the upstream server

In this example, we expect the API request to return a response body containing a token field. We can then use the value of this field with $(callouts.auth1.response.body.token).

Environment variables

API_URL: The API endpoint to use to request a token.

Set up the plugin
