# Send webhook test

Send webhook test is a command in the HeadHoncho API. Send a signed test event to one webhook now and say what the address answered. It is not retried and costs no delivery credit.

Page: https://headhoncho.app/docs/api/send_webhook_test | Part of the HeadHoncho API docs: https://headhoncho.app/docs/api | Machine-readable: https://headhoncho.app/docs/api/openapi.json | Everything in one file: https://headhoncho.app/docs/api/llms-full.txt

## The request

Reference for **Send webhook test**, HeadHoncho API v1. It is a command, sent to the base address `https://api.headhoncho.app`.

`POST /api/v1/commands/test-webhook`

The key needs the **Company settings** area at **do**. An answered call costs 1 credit; a refusal costs nothing. See [credits](https://headhoncho.app/docs/api/errors#credits).

It runs the app's own command `test-webhook`. Send an `Idempotency-Key` header with every call: the same key with the same body returns the first answer and runs nothing twice. See [the model](https://headhoncho.app/docs/api/model#idempotency).

## Parameters

| Name | Kind | Required | Description | Example |
| --- | --- | --- | --- | --- |
| `webhook_id` | id, in the JSON body | Yes | The webhook, from List webhooks. | `whk_6d21` |

## Try it with your key

Paste your key and change the values. The box builds the call as a cURL line and a fetch line, ready to copy. It never sends anything itself.

Paste your key on the web page and it fills a cURL line and a fetch line with your key and the example values. The page never sends the key anywhere. The same lines with a placeholder key are under Examples below.

## What comes back

accepted, position, webhook_id, delivery_id, event_id, delivered (true when the address answered 2xx), response_code (null when nothing answered), duration_ms and error.

It never deletes anything. It changes only what the command names, and it writes the change to the job's history with who asked for it.

## Every field in the answer

Types are read from the example answer. Money is a plain number in the company's currency. A time carries its offset from UTC (`Z` is UTC). Ids are opaque text. A field with no line of its own here has its name spelled out; the common fields mean the same on every page.

| Field | Type | Meaning |
| --- | --- | --- |
| `accepted` | true or false | True when the command ran. A command that cannot run is an error instead. |
| `position` | whole number | Where the change landed in the event log. Pass it as `after` on a read to see your own write. |
| `webhook_id` | id (text) | The id of the webhook. |
| `delivery_id` | id (text) | The id of the delivery. |
| `event_id` | id (text) | The id of the event. |
| `delivered` | true or false | The delivered. |
| `response_code` | whole number | The response code. |
| `duration_ms` | whole number | The duration ms. |
| `error` | text | The error. |

## What it sends

An event named webhook.test, signed like any other, so you can check your signature code before a real change arrives.
