How to get Owner IDs of GSTINs?

1. Log in to your ClearTax E-Invoicing sandbox account - or your ClearTax E-Invoicing production account - based on which environment auth token you want to generate.
2. On the bottom left corner click on “Settings”.
3. On the sidebar menu, click on “Integrations”.
4. You will see the list of GSTINs you have added along with the 36 character long owner_id (Owner ID column) in a table. Click on the “Download CSV” button above the table. You can use this list to map the GSTINs in your ERP to the corresponding owner_id of ClearTax.
