# API Reference

## Getting Started

### Session Information

* The Auto Insurance API requires basic `sessionInformation` (the end user's IP address and user agent) with every offer search.
* Carriers use this information as part of underwriting, compliance, and fraud-prevention checks, so it must be collected from the live user session and passed through accurately.

### Authentication & Environments

A representative from Engine by Gen will set up an account and provide an authorization token to access the Engine API.

* An **authorization token** is required to authenticate every request. Include it in the request headers; otherwise the API returns an error.
* Every request must also include an **Api-Version** header. The current supported version for the Auto Insurance API is `2026-02-25`.
* **Test and production tokens are separate.** Requests made with a test token are not reflected in performance reporting or payable events. Switch to the production token once testing is complete.
* A test token only works against the test environment, and a production token only works against production. Using a token against the wrong environment returns `401 Unauthorized`.
* For more information, see our [API Reference](https://engine.tech/docs/api-reference/#authentication) page

<table><thead><tr><th width="145.21484375">Environment</th><th>Base URL</th><th>Token Type</th></tr></thead><tbody><tr><td>Test / Dev</td><td><code>https://dev-api.engine.tech</code></td><td>Test authorization token</td></tr><tr><td>Production</td><td><code>https://api.engine.tech</code></td><td>Production authorization token</td></tr></tbody></table>

{% hint style="warning" %}
**Rate tables are environment-specific**

A `uuid` created in the test environment cannot be polled against production (and vice versa). Doing so returns `404 Not Found`.
{% endhint %}

## Step 1: Retrieve Supported Issuers

**Before submitting an offer search**, retrieve the list of supported insurance carriers:

```bash
curl --location 'https://api.engine.tech/leads/autoInsurance/issuers' \
--header 'Authorization: Bearer <AUTH_TOKEN>' \
--header 'Content-Type: application/json'
```

Example response:

```json
[
  {
    "id": "statefarm",
    "name": "State Farm",
    "logoImageUrl": "https://cdn.trellisconnect.com/sdk/v1.1/assets/images/logos/statefarm.ico"
  }
]
```

Pass the issuer's `id` as the value of `autoInsuranceInformation.currentIssuer` in your offer search:

```json
{
  "autoInsuranceInformation": {
    "currentIssuer": "statefarm"
  }
}
```

{% hint style="warning" %}
The `name` and `logoImageUrl` fields are provided for display purposes only. Use the `id` value when making requests.
{% endhint %}

***

## Step 2: Submit the Offer Search

* Set `productTypes` to `["AutomobileInsurance"]`
* Submit a POST request to `/offerSearches/`

### Request Fields

{% hint style="info" %}
Fields marked **Recommended** for `POST /offerSearches/` are technically optional, but providing them meaningfully improves quote accuracy and offer matching.

Omitting an optional field implies "no information" for that attribute.

{% hint style="success" icon="chart-line-up" %}

#### Client Tags for Attribution

Partners can optionally pass `clientTags.subId`, an array of client-defined string tags, with each offer search request.

Engine includes these tags in reporting, letting a partner attribute leads and revenue back to a specific sub-affiliate, campaign, or placement. This field has no effect on which offers are returned; it is purely for tracking.

See the [Attribution Tracking](/developer-center/channel-partner-reporting/attribution-tracking.md) page for more information
{% endhint %}

***

## Step 3: Poll for the Rate Table

Capture the `uuid` returned in the Step 1 response and issue a `GET` request to the Offer Searches endpoint:

```applescript
GET https://api.engine.tech/offerSearches/{uuid}
```

### Polling Process

1. After the POST in Step 1, poll `GET /offerSearches/{uuid}` once per second for up to 15 seconds.
2. Check `pendingResponses` on each response:
   * Not empty: Engine is still waiting on one or more partners. Keep polling.
   * Empty: Every partner has finished. Stop polling; `offers` is the final set.
3. As each partner responds, its offers are added to `offers` and that partner is removed from `pendingResponses`.

### Sample Responses

{% tabs %}
{% tab title="Search Still Pending (200 OK)" %}
Immediately after submitting the offer search, the response may show no offers yet, with one or more partners listed under `pendingResponses`:

{% hint style="success" %}

#### `200 OK`

**Endpoint:** `GET /offerSearches/{uuid}`

**Meaning:** The rate table was found and returned. `offers` may still be empty.

**Next action:** Check `offers` and `pendingResponses`. Keep polling until `pendingResponses` is empty.
{% endhint %}

**Completed searches with no offers**

An empty `offers` array and empty `pendingResponses` array means no matches were found. This is a silent failure. The request succeeded, but there are no offers to display.

Common causes include:

* Missing FCRA consent.
* State exclusions.
* Missing required fields.
* Automated risk screening.
* Carrier unavailability.

### Unsuccesful Request (4xx)

{% hint style="danger" %}

#### `400 Bad Request`

**Endpoint:** Any

**Meaning:** The request was malformed and was not processed.

**Next action:** Fix the malformed input.

Common causes:

* **Missing or invalid Api-Version header** — required on every request; it must match a supported version, such as `2026-02-25`.
* **Invalid JSON** — the request body could not be parsed.
* **Malformed UUID** — a path parameter, such as `/offerSearches/{uuid}`, used an invalid UUID format.

The response body contains error objects describing the failed field and reason.
{% endhint %}

{% hint style="warning" %}

#### `401 Unauthorized`

**Endpoint:** Any

**Meaning:** The authorization header is missing, expired, or invalid.

**Next action:** Verify the bearer token and environment. Test tokens only work with `dev-api.engine.tech`. Production tokens only work with `api.engine.tech`.
{% endhint %}

{% hint style="warning" %}

#### `404 Not Found`

**Endpoint:** `GET /offerSearches/{uuid}`

**Meaning:** The rate table UUID does not exist.

**Next action:** Verify the UUID and environment.

This can happen when:

* The UUID was copied incorrectly.
* A dev UUID is requested from production, or the reverse.
  {% endhint %}

{% hint style="danger" %}

#### `422 Unprocessable Entity`

**Endpoint:** Any

**Meaning:** The `Api-Version` header is present, but its version string is not recognized.

**Next action:** Use a supported version. See Authentication & Environments.
{% endhint %}

### Retry Request (429 & 5xx)

{% hint style="warning" %}

#### `429 Too Many Requests`

**Endpoint:** Any

**Meaning:** Too many requests were sent in a short window. This usually results from polling faster than the recommended cadence.

**Next action:** Slow polling, honor `Retry-After` when present, and retry with exponential backoff.

* Poll no more than about once per second per rate table.
* If `Retry-After` is present, wait that many seconds before retrying.
* On repeated `429` responses, back off exponentially, such as 1s, 2s, then 4s.
  {% endhint %}

{% hint style="info" %}

#### `500` / `503` Server Error

**Endpoint:** Any

**Meaning:** Engine encountered a temporary internal error or is briefly unavailable. These responses are transient and are not caused by malformed input.

**Next action:** Retry with exponential backoff within the polling window. Contact your Engine representative if the error persists.

* Retry with exponential backoff, such as 1s, 2s, then 4s.
* Do not treat a single 5xx response as a failed search. Keep polling within your timeout window.
* If 5xx responses continue past the timeout, stop polling and show a graceful error.
  {% endhint %}

## 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://even-financial.gitbook.io/developer-center/marketplace-integrations/native-api/auto-insurance/api-reference.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.
