Description

Feature Description

Integrity check is a scenario where there is a discrepancy between the amount sent in the request and the amount received from the connector, which is checked during response handling.

Possible Implementation

Refer to relevant PRs for Stripe/Xendit and add the integrity checks in the ACI connector and hardcode the amount values going to the connector to test the integrity check

Research direction
Examine the implementation of integrity checks in the Stripe and Xendit connectors by reviewing linked PRs such as #8049. Then apply the same pattern to the ACI connector's response handling for Capture, Refund, and RSync flows. Hardcode test amounts to validate the integrity check logic. Key files to modify would be in the ACI connector module under crates/router/src/connector/aci/.
