Calling POST method on Zoho Desk API using ZOHODESK.request method results in "This HTTP Method is not allowed" error

Hi,

I'm trying to merge 2 tickets using the ZohoDesk API, triggered from my Zoho Desk Extension.

I'm using the Zoho Desk Merge Tickets API do to this. I've tested this API separately in PostMan, so can confirm that it is working.

When I try to replicate this call from my extension, using a configured connection and and the `ZOHODESK.Request` method, I get back an object with error code "Method Not Allowed" and message "This HTTP method is not allowed on this URL."

This is an endpoint that requires using HTTP POST. I've had no trouble with GET methods using ZOHODESK.Request. Do I need to somehow enable the connection for POST methods?

Here is the code that is calling the merge method:

const mergeTickets = async (sourceTicketId: string, targetTicketId: string) => {
const orgId = await getOrgId(); //shortcut method for returning the orgID
const request = {
url: `https://desk.zoho.com/api/v1/tickets/${sourceTicketId}/merge`,
type: 'POST',
headers: { 'Content-Type': 'application/json', orgId: orgId },
connectionLinkName: 'myzohodeskconnnection',
responseType: 'json',
postBody: { ids: [targetTicketId] },
data: {}
};

const response = await ZOHODESK.request(request);
console.log('Merge Response', response);
return response;
};

Here is the logged response:

{
"data": {
"statusMessage": {
"errorCode": "METHOD_NOT_ALLOWED",
"message": "This HTTP method is not allowed on this URL."
},
"status": "true"
},
"type": "application/json",
"name": "Untitled"
}
