Partial authorisations (or "partial approvals") allow an issuing bank to approve a transaction for less than the total transaction amount if the shopper does not have sufficient funds. You can decide to accept partial authorisations; there are no restrictions based on your MCC.
When the issuing bank authorises a partial amount instead of declining for insufficient funds, they also provide the authorised amount. You have four options:
- Prompt the cardholder for a second payment method to collect the outstanding balance.
- Cancel the transaction.
This removes the hold for the partially authorised amount on the shopper's statement. - Capture the partially authorised amount and take no further action.
- For tokenized payments, you can retry the original payment method at a later time to collect the outstanding balance.
You can combine these options. For example, you can set a minimum amount for a partial authorization and cancel the transaction if the shopper does not have sufficient funds.
If you accept a partial authorisation, the amount will be captured and the transaction is complete. Any authorisation for the outstanding balance is a separate transaction.

Test partial authorisations for Ecommerce transactions
To verify that you can process partial authorisations correctly, submit a /payments request with the parameter additionalData.allowPartialAuth = true and details from one of the following cards:
| Test card | Expiry date | CVC | Amount |
|---|---|---|---|
| 4166 6766 6766 6746 (Visa) | 03/2030 | 737 | Any amount ending in 139 |
| 2222 4000 1000 0008 (Mastercard) | 03/2030 | 737 | Any amount ending in 139 |
The partially authorised amount is calculated by deducting 100 (in minor units) from the original amount. For example, if the request amount is 1139, the authorisedAmountValue in the response is 1039.
