# Glossary

**What this is:** every term in these docs is defined inline the first time it's used (look for a "New term" callout). This page is a quick backstop when you land on a page mid-way and need a definition without hunting for where it was first introduced.

| Term                       | Plain definition                                                                                                                                                                                                                                                    |
| -------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Webhook**                | An HTTP `POST` that InsurGrid sends to a URL you control when something happens — you don't ask us for the data, we push it to you.                                                                                                                                 |
| **Endpoint**               | The URL on your server that receives a webhook `POST`.                                                                                                                                                                                                              |
| **2xx**                    | Any HTTP status code from 200 to 299 (e.g. `200 OK`). To InsurGrid it means "received, thanks" — anything else, or a timeout, means delivery failed and gets retried.                                                                                               |
| **HMAC signature**         | A fingerprint of a webhook's raw body, computed with a shared secret. Because only you and InsurGrid know the secret, a matching fingerprint proves the request is genuine and unaltered. Sent in the `x-signature` header, computed as HMAC-SHA256.                |
| **Signing secret**         | The secret used to compute and verify the HMAC signature on webhooks. Shown once when generated; stays on your server, never sent to InsurGrid.                                                                                                                     |
| **Bearer token**           | A secret string sent as `Authorization: Bearer <token>` that authenticates an API call — whoever holds it can call the API as you.                                                                                                                                  |
| **Management token**       | The specific bearer token used for Forms API calls (creating, reading, and publishing forms and reading submissions) — issued server-to-server by InsurGrid.                                                                                                        |
| **Idempotency key**        | A value you generate (`Idempotency-Key` header) and send on a write request, so retrying the exact same request with the same key never performs the operation twice.                                                                                               |
| **Cursor**                 | An opaque value returned by a list endpoint (`next_cursor`) that you pass back to fetch the next page. Don't construct or parse it yourself.                                                                                                                        |
| **At-least-once delivery** | InsurGrid's delivery guarantee for webhooks: an event will be delivered, but may occasionally be delivered more than once. Your handler must be safe to run twice on the same event.                                                                                |
| **Topic**                  | The kind of event a webhook carries — `client-submission` for extracted policy data, `form-submission` for a completed intake form. You register a URL per topic.                                                                                                   |
| **Agency vs. agent**       | A form (and its submissions) is owned either by an **agency** (shared across everyone in it) or by a specific **agent** within that agency. Every form's public fill link is per agent, regardless of ownership scope — that's who a submission gets attributed to. |
| **ACORD**                  | The standardized insurance industry forms (e.g. ACORD 125, 140) that InsurGrid can auto-fill from a completed intake form and return to you as PDFs.                                                                                                                |

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.insurgrid.com/glossary.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.
