I run 2 separate Zoho CRM systems.

They communicate with each other via webhooks.

For example Zoho CRM A has a workflow rule that triggers a webhook which inserts a new Account record in Zoho CRM B.

I created/configured these webhooks in the Setup > Automation > Actions > Webhooks

They are based on the API V1 format.

I have spent a long time reading the migration guide but cannot figure out how to re-implement these webhooks in the API V2 format.

For example the authentication in V1 is just a field in the custom parameter section (authtoken).

In V2 it seems to be a separate step using a GET follwed by a POST of the actual data to be inserted as a new record.  So I cannot figure out how to do this in the GUI Webhook editor as you can only choose GET or POST - not GET followed by POST.

I am starting to think that the built in webhook creator/editor in the Zoho CRM Setup section is possibly not capable of sending data to another Zoho CRM using the V2 API.

In which case in am pretty screwed.
