# Retrying schedule

Your endpoint must respond with an HTTP `2xx` status code to acknowledge receipt. Any other response is treated as a failure and the webhook is retried automatically.

Each webhook is retried on the following schedule, with each attempt starting after the previous one fails:

* Immediately
* After 5 seconds
* After 5 minutes
* After 30 minutes
* After 2 hours
* After 5 hours
* After 10 hours
* After a further 10 hours

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.txn.io/api-basics/webhooks/retrying-schedule.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
