# Callback Service
TripLink supports callback to customer interfaces in multiple business scenarios. Customers can implement their own business logic in the callback interface.
The callback is based on the HTTP/HTTPS protocol with the POST method, and all request bodies are in JSON format with all characters encoded in UTF-8.
The callback process is considered Failed if any of the following situations occur: request failure, request timeout, or response status code other than 2XX.
The callback is divided into Synchronous and Asynchronous types. Synchronous requests must respond in a timely manner and have no retry mechanism, while asynchronous requests do not need to respond in a timely manner and have a retry mechanism.
# Callback List
| Name | Type | Response Time | Retry Count | Retry Interval |
|---|---|---|---|---|
| Authorization Decision Callback | Synchronous | 3s | N/A | N/A |
| Authorization Result Notification | Asynchronous | 9s | 20 | N × 2min |
| Settlement Result Notification | Asynchronous | 9s | 20 | N × 2min |
| CreateCard Result Notification | Asynchronous | 9s | 20 | N × 2min |
| CloseCard Result Notification | Asynchronous | 9s | 20 | N × 2min |
The client can check the items they want to be notified of, and will only be notified if they are checked.
# Authorization Decision Callback
Before approving an authorization request, TripLink will call back to this customer interface, allowing the customer to implement their own risk control and authorization decisions.
If the callback fails, TripLink will degrade to using default decision results for the customer, as outlined in the Callback Parameters.
If the callback fails continuously for 10 times, the system will no longer request the customer interface and will directly degrade, requiring the customer to manually re-enable it.
