Accepting Callbacks in a Zoho Creator application

Hello -

I have a Zoho Creator application that needs to query data from views (asyncronously) in Zoho Analytics. Using the Zoho Analytics API, I can submit an Export Job that includes a CallbackURL, whereby Analytics will POST to the URL when the export job is complete so that I can proceed to collect the results via a second call to Analytics.

However, I'm not sure how to create Callback URL as I don't see a way for the CallbackURL field in Analytics to specify any headers for the required authtokens and other fields needed by the Creator API.

I created a Form in my Creator application with a single field called Payload. I then published that Form hoping that I could then use the Creator Add Records API to update that Form without an authtoken, but it gives me a 1030 Authorization Failure error message when I try a simple call.

So, is there a way to either:

1. Specify a simple webhook in Creator that can trigger a function, or

2. Somehow make a Creator form public so that a URL POST method can be performed without any headers, or

3. How can I specify the "CallbackUrl" field in the Analytics API to include the required header info?

I'm sure others must have applications that need to receive simple callbacks, so I'm hopeful there is an easy solution.

Many thanks,

Alex
