Each incremental authorisation generates its own receiptId.
If an authorisation has been incremented, any subsequent void request must reference the receiptId of the original pre-authorisation transaction.
Using the receiptId returned following an incremental authorisation will result in an error.
The void amount must be the sum of the original authorisation amount and all successful increments. Any attempt to process a partial void, the sum of any but not all authorisations and increments, will result in an error.
For example:
- Initial preAuth: £100
- incrementalAuth request amount: £20
- incrementalAuth request amount: £30
- Total authorised amount after increments: £150
To void this transaction:
- Use the receiptId of the Initial preAuth.
- Submit a void request for £150.
