Troubles setting up Webhooks

Troubles setting up Webhooks

Hi Zoho Creator team!

I'm facing some difficulties setting up a request from an external application (Docparser)

I setup a 'on succes' action to send a PDF file to Docparser. When the document is parsed, I want docparser to send me the parsed data. This data should be updated in the record the file was uploaded to.

While sending the document I also provided a remote_id to identify the record for updating the record values.

At first it looked like a straightforward thing to do with the creator update API link:  https://creator.zoho.com/api/<ownername>/<format>/<applicationName>/form/<formName>/record/update

But I got confused when I saw the Sample request is html.

At Docparser I get 4 Content Types available:
Form Data
JSON
XML (CDATA Escaped)
XML (Encoded)

I can add additional headers for which I chose:
auththoken: *************(my Auththoken provided by Zoho)
scope: creatorapi

After the headers I can write the HTTP Body Payload Template in the chosen Content Type:

I keep getting several errors in different setups:
{"code":2945,"message":"INVALID_TICKET"}

Or:
<html><head><style>
body {
font-size: 14px;
font-family: "Verfana";
}
div {
margin-top:150px;
vertical-align: middle;
text-align: center;
}
</style></head><body><div>An error has occurred. It has been reported to Zoho Creator support. We will look into this issue .<br> Sorry for the inconvenience caused.<p><p>Go to <a href='%2F'>Home</a></div></body></html>

The documentation on  https://www.zoho.com/creator/help/api/rest-api/rest-api-edit-records.html really don't helps me any further.

Can someone help me with this problem?

Tnx!
Sam
