Exceptions Handling for Push Payments

Instant push to card transactions follow a good funds model. Funds must be available before a disbursement is initiated. This means:

The merchant's account must be pre-funded before disbursements are processed
TabaPay does not advance or float funds on behalf of the merchant
Once funds leave the sender's account, they cannot be recalled. The receiving institution is not obligated to return them.

To eliminate sender errors, merchants must implement confirmation screens, double-entry validation, and thorough testing. End users must be informed that the transaction is final before initiating.

❗️
Unsupported Reversals of Disbursements
Mastercard does not support reversals of disbursements under any circumstances.
In cases where the recipient reports that they did not receive the funds and the issuer confirms non-receipt through Visa's Proof of Posting process, Visa supports a good faith adjustment process, which requires issuer approval. Visa rules do not permit adjustments of disbursements under any other circumstances.
