API Key Authentication

Authentication is required in order to interact with Batch's APIs.

Batch implements authentication using API Keys, that we call the "REST API Key". You can find it on your dashboard.

Please make sure that you keep this key secret. You should never use it in client apps to call APIs from there as it would easily be extractable.

How to authenticate

In order to authenticate your requests, add your REST API Key in the Authorization header and prefix it by Bearer. Example: Authorization: Bearer bcd38d9rfb38ra28.

Query parameters
