4. Verification and Processing: The request goes through NPCI to the customer’s bank for verification with the UIDAI database.
5. Confirmation: A confirmation is sent back to the merchant.

Earn Commission with Aadhaar Pay API Integration

You can earn a commission by integrating Aadhaar Pay API; however, it is important to note that the commission is not typically paid by the AEPS Aadhaar Enabled Payment System service provider like Noble wbe studio but is instead a service charge you can levy on your customers. This differs from standard AEPS transactions where the agent earns a commission directly from the bank/service provider. 

How You Earn Commission

• Transaction-Based Earnings: You earn a fixed amount or percentage for each successful transaction. The Aeps commission structure is tiered and depends on the transaction amount and the specific service provider you partner with.
• Service Types: Commissions are typically earned on services such as:

  • Cash Deposits: Noble web studio also offer a commission on cash deposits.
  • Mini Statements: These typically offer a small, fixed commission (around ₹1-₹2).

• Aadhaar Pay for Merchants: For Aadhaar Pay specifically (distinct from AEPS which has a ₹10,000 limit), which allows transactions up to ₹50,000, Noble web studio don’t offer a direct commission but allow you the option to charge your customer a service fee (e.g., 1% of the transaction amount).
