To configure this credential, you'll need:

* An **API Key**: In MISP, these are called Automation keys. Get an automation key from **Event Actions > Automation**. Refer to [MISP's automation keys documentation](https://www.circl.lu/doc/misp/automation/#automation-key) for instructions on generating more keys.
* A **Base URL**: Your MISP URL.
* Select whether to **Allow Unauthorized Certificates**: If turned on, the credential will connect even if SSL certificate validation fails.
