1. Open the installed payment module and copy its callback URL. Use the exact HTTPS address for the intended installation and environment.
2. In the provider's webhook or notification settings, configure that endpoint with the events and API version required by the HostBill integration. For Stripe modules, follow HostBill's shared webhook guide and any additional module-specific events.
3. Copy the endpoint's signing secret into the matching HostBill field where required. A provider API key and a webhook signing secret serve different purposes.
4. Check that the endpoint can receive provider requests without an interactive login, maintenance screen or browser challenge. Apply narrowly scoped network rules that preserve the gateway's authentication checks.
5. Run a controlled payment and inspect the provider's event-delivery result. Then open Payments > Gateway Log, the HostBill transaction and the target invoice.
6. Verify that a single receipt was recorded for the correct amount, currency and invoice, and that the expected service action completed only once.

Search by the provider transaction reference before recording a manual payment. Establish whether the event was absent, rejected or processed without the expected invoice association. Correct the endpoint or secret, then use a supported event-redelivery process when appropriate. Reconcile a manually recorded receipt with any later callback to prevent duplicate credit.

In this example the payment provider shows a completed receipt, but HostBill still displays the related invoice as unpaid. Record the provider transaction reference, event ID, amount, currency, destination URL and delivery response. Search the HostBill gateway log and transactions for that reference before attempting a correction.

If the event went to the old installation address, update the endpoint according to the installed gateway module and use the provider's supported redelivery procedure. Then confirm that the receipt appears once, the intended invoice balance changes correctly and provisioning runs once. If a staff member already recorded the verified payment manually, reconcile that entry with the returning callback rather than allowing a second credit.
