API Authentication Process
How to get API Authorization key – Any Aggregator
Every seller will be provided with a base64 encoded secret key. Sellers can log into Seller Portal to (re-)generate their API Authorization Key and click on your name in the upper right hand corner and select the “Account Info” link.

Scroll to the bottom of the page to the section called API Authorization Key.
Click the “Generate New Key” button.
Copy and paste your key to somewhere safe as this does not show after you leave this page. Your aggregator will need this API Authorization Key in order to connect on your behalf.
