Auto Assign Reporting Tag Zoho Books

Automatically creates and assigns a Reporting Tag to an Invoice Line Item, if there is an associated Project. Can be adapted to work on other modules.

Configuration

This function relies heavily on the Zoho Books API. To access this API, we need to create a Custom Connection to Zoho Books. Here are the steps you need to take to create this Custom Connection:

Create API Credentials: Gives you a Client ID and Client Secret to use in the next step.

  1. Go to the Zoho API Console
  2. Click Add Client and select Server-based Applications
  3. Fill in the following fields:
    • Client Name -> Zoho Books API
    • Homepage URL -> https://books.zoho.com
    • Authorized Redirect URIs -> https://deluge.zoho.com/delugeauth/callback
  4. Click Update
  5. Notice the Client ID and Client Secret here. You will need these in the next step, so keep this tab open.
