# Response

Once the transaction is complete, the user will be redirected to the given request URL.

* If the transaction is successful, user will be redirected automatically to given success\_url
* If transaction gets failed, user will be redirected to the provided failure\_url

In both cases, payment\_id will be provided as a query parameter; hence you can use this payment\_id as transaction\_id to retrieve transaction details and status information from the given API.

More details about API is explained in [API reference section](/technical-guide/api-encryption-key-guide.md).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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, and the optional `goal` query parameter:

```
GET https://docs.paykun.com/technical-guide/web-integration/checkout-integration/web-integration-response.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
