# WhatsApp Group Lifecycle Update Webhook Examples

> Handle WhatsApp group creation and deletion results.

<Note>For the exhaustive schema-derived catalog, see [all examples](/en/api-reference/guides/examples/webhook-examples/webhook-payload-examples).</Note>

## What it is

Handle WhatsApp group creation and deletion results.

## Before you begin

* Create a public HTTPS endpoint in your application.
* Configure a YCloud webhook endpoint for the event types you need.
* Store the endpoint signing secret securely.
* Make event processing idempotent.

## How it works

YCloud sends an HTTP `POST` request when the event occurs. Verify the signature, durably record the event, return a `2xx` response, and process slow work asynchronously.

## Request

The scenarios below show requests delivered to your webhook URL. Treat the event `id` as the delivery identifier and use `type` to route the payload.

## Response

Return a `2xx` status after accepting the event.

```http theme={"theme":{"light":"github-light","dark":"github-dark"}}
HTTP/1.1 200 OK
```

<Note>For endpoint setup, signature validation, and retry behavior, see [Configure webhooks](/en/api-reference/guides/api-fundamentals/configure-webhooks).</Note>

## Group Created

When a WhatsApp group is successfully created, you will receive a webhook with the following payload structure:

### Request

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "id": "evt_group_lifecycle_123",
  "type": "whatsapp.group.lifecycle_update",
  "apiVersion": "v2",
  "createTime": "2026-05-13T00:00:00.000Z",
  "whatsappGroup": {
    "wabaId": "123456789012345",
    "displayPhoneNumber": "16315551111",
    "phoneNumberId": "1234567890123456",
    "field": "group_lifecycle_update",
    "type": "group_create",
    "requestId": "REQ_1",
    "status": "created",
    "groupId": "Y2FwaV9ncm91cDpFWEFNUExFX0dST1VQX0lE",
    "inviteLink": "https://chat.whatsapp.com/AbCdEfGhIjK",
    "subject": "New Purchase Inquiry",
    "description": "Group for purchase inquiries.",
    "joinApprovalMode": "auto_approve",
    "webhookTime": "2026-05-13T00:00:00.000Z",
    "dedupeKey": "123456789012345|REQ_1|group_lifecycle_update|group_create|created"
  }
}
```

### Response

Acknowledge the delivery after durably accepting the event.

```http theme={"theme":{"light":"github-light","dark":"github-dark"}}
HTTP/1.1 200 OK
```

### Explanation

Route the event by `type`, deduplicate it by `id`, and move slow or failure-prone work to an asynchronous processor.

## Group Deleted

When a WhatsApp group is deleted, you will receive a webhook with the following payload structure:

### Request

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "id": "evt_group_lifecycle_124",
  "type": "whatsapp.group.lifecycle_update",
  "apiVersion": "v2",
  "createTime": "2026-05-13T00:00:00.000Z",
  "whatsappGroup": {
    "wabaId": "123456789012345",
    "field": "group_lifecycle_update",
    "type": "group_delete",
    "requestId": "REQ_DELETE",
    "status": "deleted",
    "groupId": "Y2FwaV9ncm91cDpFWEFNUExFX0dST1VQX0lE",
    "webhookTime": "2026-05-13T00:00:00.000Z"
  }
}
```

### Response

Acknowledge the delivery after durably accepting the event.

```http theme={"theme":{"light":"github-light","dark":"github-dark"}}
HTTP/1.1 200 OK
```

### Explanation

* **type**: Always `whatsapp.group.lifecycle_update` for group lifecycle events
* **whatsappGroup**: Contains the group lifecycle result details
  * **field**: Always `group_lifecycle_update`
  * **type**: The lifecycle action, such as `group_create` or `group_delete`
  * **requestId**: The request ID returned by the asynchronous group API operation
  * **status**: The normalized result status, such as `created`, `deleted`, or `failed`
  * **groupId**: The WhatsApp group ID
  * **inviteLink**: The group invite link, included when group creation succeeds
  * **dedupeKey**: Idempotency key for deduplicating group lifecycle webhook events
