Get an access token for OpenID authentication
NOTE: Many of the endpoints in the Pismo API require you to pass a JWT that you generated which includes a Pismo account ID (uid or account_id) or an account ID from an external system used in place of the Pismo account ID (external_account_id). Further calls to Pismo endpoints will require this token in the Authorization header.
For more information, refer to Endpoints that require an account-specific token and Endpoints that require an external ID-specific token.
