Authorizations

Payblr supports an External Host Interface (EHI) integration for real-time transaction authorization and transaction event delivery.

Through this integration, Payblr forwards EHI transaction messages to your configured endpoint. Your system validates the request, processes the EHI JSON payload, and returns the required response based on the message type.

Authorization messages may require your system to return an approve, decline, or partial approval decision. Other transaction lifecycle messages, such as advice, reversal, financial, chargeback, and cut-off messages, generally require an acknowledgement or cut-off result.
