put https://api.elliemae.com/webhook/v1/functions/auth/
Updates the custom auth parameters for the custom auth function.
When using the PUT call to manage webhook custom auth config, any existing values will be fully replaced with the new payload - be sure to include all necessary fields to avoid unintental data loss. To update the Custom Auth Credentials only, use the PATCH /webhook/v1/functions/auth/{functionId} endpoint.
