By submitting your API Key in the X-Api-Key header of any of your created requests, you will need to authenticate your requests to the Postman API.

This API key is used to give access to authorized data.

You can also store your API key in an environment variable with the name postman-api-key. The Postman API collection can access the API key automatically.

60 requests per minute are required to access the API with the key.

Each response of an API contains the following set of headers to identify your consumption status.
