# Webhooks

## Webhook Callbacks — Overview

This section documents outgoing webhook payloads we send to client endpoints when declaration page is uploaded. Current supported payloads:

* **Auto**
* **Homeowners**

### Delivery contract

* **Method:** `POST`
* **Content-Type:** `application/json`
* **Retry policy:** Exponential backoff, 3 retries by default. See Retry Behavior.
* **Idempotency:** Each webhook contains `policy.policy_type` and `policy.policy_number` entries to correlate events.

### Best practices for integrators

1. Always respond `200 OK` quickly. If temporary failure occurs, respond with `5xx` or timeout; we will retry.
2. Store `policy.policy_type`  and `policy.policy_number` as your primary key for mapping.
3. Be tolerant of extra fields — payloads may add fields in future versions.
4. Use the downloadable JSON Schema for strict validation.

## 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.insurgrid.com/data-webhook-page/webhooks.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.
