# Webhooks

> Webhooks are triggered when a significant event occurs within the system that a partner might be interested in. The payload contains details about the event type and the associated data.

## Webhook Console

Webhooks can be managed in the Webhook Console. Here, you can:

* Register new webhooks
* Manage your current webhooks
* See the webhook documentation

<Frame caption="The Webhook Console">

</Frame>

### Fields

* **Label**: The name of your webhook. If your webhook caused an error or did not respond, you will see a *danger* icon next to the name. If you hover over it, you will see more information
* **Status**: Whether your webhook is enabled
* **Topics**: Webhooks can register for different topics
* **Ping**: After creating a webhook, you can press this button to force sending an event to the webhook in order to trigger it

## Register Webhook

Webhooks can be registered in the Partner Area. Click the Webhook navigation entry, and then the "Register Webhook" button.

</Frame>

The webhook URL has to be a `https://` URL that points to where you want the webhook to go. You can select which topics you're interested in for the webhook

Once you created the webhook, you will be provided the `webhook secret` in the next screen. This is needed to validate the webhook signature.

## Implement Webhooks

The Partner Area webhook console provides sample code for webhook signature validation. However, additional information can be found below.

Overview

* Webhook ID: newEvent
* Method: POST
* Content Type: application/json
* Authentication: HMAC-SHA256 signature (via headers)
* Trigger: Emitted when a relevant customer or platform event occurs

### Receiving Webhook Requests

Iron will send webhook notifications to the endpoint URL you’ve registered during integration setup. Each request includes headers for verification, and a JSON body describing the event.

#### HTTP Headers

Iron follows the Standard Webhooks specification:

**Headers**

**content-type**: Always set to application/json.

**webhook-id**: Unique UUID (v4) of the delivery attempt. Use this for logging and idempotency.

**webhook-timestamp**: Unix timestamp (in seconds) indicating when the webhook was sent.

**webhook-signature** : Signature used to verify request authenticity. Format: `v1=\<HMAC\_SHA256>`

### Signature Verification

To ensure webhook authenticity, verify the signature using your secret key:

<Steps>
  <Step>
    Extract the `webhook-timestamp` and `webhook-signature` from the headers.
  </Step>

  <Step>
    Remove the `v1=` prefix from the signature.
  </Step>

  <Step>
    Concatenate `webhook-timestamp` + `raw_body` (no whitespace or formatting).
  </Step>

  <Step>
    Compute the HMAC-SHA256 digest using your webhook secret key.
  </Step>

  <Step>
    Use constant-time comparison to check if the computed digest matches the signature.
  </Step>
</Steps>

<Warning>
  Always verify the signature using constant-time comparison to prevent timing attacks.
</Warning>

### Webhook Payload

Webhook requests include a top-level `WebhookContainer` object. The message field varies depending on the event type.

#### Example Payloads

Below, you can find example payloads for all possible events that the webhooks payload can deliver.

### Payload Schema

**WebhookContainer** (object)

| Field     | Type   | Required | Description                                         |
| --------- | ------ | -------- | --------------------------------------------------- |
| type      | string | Yes      | Type of event. See `WebhookEventType`.              |
| timestamp | string | Yes      | ISO 8601 timestamp of when the event was triggered. |
| data      | object | Yes      | Event-specific data payload.                        |

**WebhookNotification** (inside data)

| Field        | Type   | Required | Description                                   |
| ------------ | ------ | -------- | --------------------------------------------- |

| message      | object | Yes      | The core event message. Varies by event type. |

### Supported Event Types

Each message object follows a typed schema depending on the type of event.

1. **WebhookEventMessage**

General-purpose events (e.g., onboarding, registration).

```json theme={null}
{  
  "id": "uuid",  
  "kind": "Transaction" | "NewBankAccount" | "NewAutoramp" | "DepositAddressCreated" | "CustomerCreated"  
}
```

2. **WebhookFiatAddressStatusMessage**

Status of a fiat vIBAN account.

```json theme={null}
{  
  "id": "uuid",  
  "status": "AuthorizationRequired" | "AuthorizationFailed" | "RegistrationPending" | "RegistrationFailed" | "Registered"  
}
```

3. **WebhookAutorampStatusMessage**

Status changes in an Autoramp.

```json theme={null}
{
  "id": "uuid",
  "status": "Created" | "EditPending" | "Authorized" | "DepositAccountAdded" | "Approved" | "Rejected" | "Cancelled"
}
```

4. **WebhookTransactionStatusMessage**

Real-time updates on transactions.

```json theme={null}
{  
  "id": "uuid",  
  "status": "Pending" | "PayoutPending" | "Payout" | "PayoutCompleted" | "Completed" | "Failed" | "InAmlReview" | "AmlRejected" | "AmountRejected" | "FraudRejected",
  "transaction_status": "FundsReviewInProgress" | "ConversionInProgress" | "PayoutInProgress" | "Completed" | "Failed" | "RejectedAml" | "RejectedFraud" | "RejectedMinAmount",
  "transaction_hash": "string (optional)"
}
```

<Note>
  The `status` field is **deprecated**. Use `transaction_status` instead for the current transaction state.

  The `transaction_hash` field is only present when the payout destination is a blockchain address (crypto payouts).
</Note>

5. **WebhookCustomerStatusMessage**

Customer onboarding and compliance status.

```json theme={null}
{  
  "id": "uuid",  
  "status": "UserRequired" | "SigningsRequired" | "IdentificationRequired" | "Active" | "Suspended"  
}
```

6. **WebhookPingMessage**

Sent during webhook setup or testing.

```json theme={null}
{  
  "id": "uuid"  
}
```

7. **WebhookIdentificationStatusMessage**

Identification status during KYC/KYB process.

```json theme={null}
{  
  "id": "uuid",  
  "status": "Pending" | "Processed" | "PendingReview" | "Approved" | "Declined" | "Expired"  
}
```

`Pending` → Customer has not started the process

`Processed` → Customer has completed the input process

`PendingReview` → Identification is ready for review by Compliance Team

`Approved` → Identification has been approved by Compliance Team

`Declined` → Identification has been declined by Compliance Team

`Expired` → The identification process was not completed and has been expired

### Response

Your webhook endpoint must return:

`HTTP/1.1 200 OK`

Return 200 to acknowledge successful receipt. Any other status code may cause the webhook to be retried.

<Note>
  We recommend logging all webhook-id and response statuses for audit and troubleshooting purposes.
</Note>

## Error Handling & Retries

* If your service remains unavailable, Iron may pause webhook delivery.
* Retry attempts include the same webhook-id for deduplication.
* Webhooks that fail (non-2xx status or timeout) will be retried with exponential backoff.
* You can see failing webhooks in the Partner Area

## Sample Signature

```bash theme={null}
Secret: whsec_1s/keE/2+3eQUBc+7kedMAFRoM0twsrBYPpGWbt2/csF6pbMws9RMDRU1wtRas0PwDYgDd3t7mamKhO4LBjBiQ
