DELETE
https://api.us.nylas.com/v3/connectors/{provider}/creds/{id}Delete credential
Deletes the credential with the specified ID. You can't delete a connector's default (active) credential, only a non-default one. Any grants that use the deleted credential stop working right away.
To learn what gets removed and when, see Deleting resources and data.
Works with an API key or an IAM API key with the connector_credentials.delete permission.
