Dynamically get Project Template ID (for Zoho Projects) in Zoho Flow

Dynamically get Project Template ID (for Zoho Projects) in Zoho Flow

Good afternoon,

I'm trying to create a new project with the Zoho Projects API, when adding a new Contact in Zoho CRM.
For this I am using Zoho Flow and I need to insert the "template_id".

This id is visible inside the url in Zoho Projects, in this case "108320000001592001":



It is also visible inside Flow.
When I insert the basic "insert project" module and look at the dropdown field:



But I cannot figure out how to get this ID inside a custom function. There doesn't seem to be any API option to find this ID and hard coding it into my code (as suggested by Zoho support) is not a real solution for me. There are 59 templates, and they may change over time.

Could you please help me out with this?

Best regards,
Nando
