Webhook Events

Xobito sends outbound webhooks across these groups: contacts / statuses / sources CRUD (9 events), message delivery status (4 events: sent / delivered / read / failed), and inbound messages (message.received). CRUD events use the contact-style payload envelope. Message delivery and inbound events use a simpler payload — see below.

CRUD events (contacts / statuses / sources)

Event	`model`	`event`	Fires when
Contact created	`App\Models\Tenant\Contact`	`created`	A contact is added
Contact updated	`App\Models\Tenant\Contact`	`updated`	A contact is modified
Contact deleted	`App\Models\Tenant\Contact`	`deleted`	A contact is removed
Status created	`App\Models\Tenant\Status`	`created`	A status is added
Status updated	`App\Models\Tenant\Status`	`updated`	A status is modified
Status deleted	`App\Models\Tenant\Status`	`deleted`	A status is removed
Source created	`App\Models\Tenant\Source`	`created`	A source is added
Source updated	`App\Models\Tenant\Source`	`updated`	A source is modified
Source deleted	`App\Models\Tenant\Source`	`deleted`	A source is removed

Message delivery status events

Live as of 2026-05-28. Fires every time Meta reports a status change for a message you sent via the Send Message endpoints.

Event	`model`	`event`	Fires when
Message sent	`WhatsAppMessage`	`message.sent`	WhatsApp accepted the message from us
Message delivered	`WhatsAppMessage`	`message.delivered`	Recipient’s device received the message
Message read	`WhatsAppMessage`	`message.read`	Recipient opened the message (only if read receipts enabled on their side)
Message failed	`WhatsAppMessage`	`message.failed`	Delivery failed — `error_message` populated

Mapping back to your record: the data.message_id is the exact same wamid.* returned in the data.whatsapp_response.messages[0].id field of every successful send response. Keep a (message_id → your_record_id) table and match on it. Headers for message delivery webhooks:

Header	Value
`Content-Type`	`application/json`
`X-Webhook-Signature`	HMAC-SHA256 of the body using your signing secret
`X-Webhook-Event`	e.g. `message.delivered`
`X-Webhook-Timestamp`	ISO 8601 timestamp
`User-Agent`	`whatsmark-Webhook/1.0`

Example payload — `message.sent`

The first (sent) event also includes the outbound message content (text + type) when available, so you can mirror messages sent from the dashboard — not just ones you sent via the API. (delivered / read / failed events omit content; you already have it from sent.)

{
  "event": "message.sent",
  "model": "WhatsAppMessage",
  "data": {
    "message_id": "wamid.HBgMOTE3OTg0OTM5ODcxFQIAERgSOTkxOTdCMjQ1N0JENjc2RjM5AA==",
    "status": "sent",
    "error_message": null,
    "text": "Hi Rahul, your order has shipped.",
    "type": "text",
    "tenant_id": 6
  },
  "timestamp": "2026-05-28T14:50:56+00:00"
}

Example payload — `message.delivered`

{
  "event": "message.delivered",
  "model": "WhatsAppMessage",
  "data": {
    "message_id": "wamid.HBgMOTE3OTg0OTM5ODcxFQIAERgSOTkxOTdCMjQ1N0JENjc2RjM5AA==",
    "status": "delivered",
    "error_message": null,
    "tenant_id": 6
  },
  "timestamp": "2026-05-28T14:50:57+00:00"
}

Example payload — `message.read`

{
  "event": "message.read",
  "model": "WhatsAppMessage",
  "data": {
    "message_id": "wamid.HBgMOTE3OTg0OTM5ODcxFQIAERgSOTkxOTdCMjQ1N0JENjc2RjM5AA==",
    "status": "read",
    "error_message": null,
    "tenant_id": 6
  },
  "timestamp": "2026-05-28T14:51:27+00:00"
}

Example payload — `message.failed`

{
  "event": "message.failed",
  "model": "WhatsAppMessage",
  "data": {
    "message_id": "wamid.HBgM...",
    "status": "failed",
    "error_message": "Recipient phone number not on WhatsApp",
    "tenant_id": 6
  },
  "timestamp": "2026-05-28T14:52:10+00:00"
}

Idempotency: Meta occasionally retries status webhooks to us, which can result in duplicate POSTs to your URL. Dedupe on your end by the (message_id, status) pair — ignore the second if you’ve already processed it.

Ordering is best-effort. Network latency means delivered may occasionally arrive before sent, or read before delivered. Compare timestamps if order matters to you.

Inbound message events

Fires every time a contact sends a message to your WhatsApp number. Lets you mirror the full two-way conversation on your side.

Event	`model`	`event`	Fires when
Message received	`WhatsAppMessage`	`message.received`	A contact sends you any message (text, media, button tap, reaction, location, …)

Headers — same as delivery events (X-Webhook-Signature, X-Webhook-Event: message.received, X-Webhook-Timestamp, User-Agent).

Example payload — text

{
  "event": "message.received",
  "model": "WhatsAppMessage",
  "data": {
    "message_id": "wamid.HBgMOTE3OTg0OTM5ODcxFQIAEhgg...",
    "from": "919909919284",
    "contact_name": "Rahul Patel",
    "type": "text",
    "text": "Yes, please send the details",
    "media": null,
    "media_filename": null,
    "reply_to_message_id": null,
    "tenant_id": 6
  },
  "timestamp": "2026-06-01T09:16:53+00:00"
}

Example payload — media (image/document/audio/video)

{
  "event": "message.received",
  "model": "WhatsAppMessage",
  "data": {
    "message_id": "wamid.HBgM...",
    "from": "919909919284",
    "contact_name": "Rahul Patel",
    "type": "image",
    "text": "optional caption, or null",
    "media": "https://dash.example.com/storage/whatsapp-attachments/media_6a1d793c09e0b.jpg",
    "media_filename": "media_6a1d793c09e0b.jpg",
    "reply_to_message_id": null,
    "tenant_id": 6
  },
  "timestamp": "2026-06-01T12:21:16+00:00"
}

Fields

Field	Type	Notes
`message_id`	string	WhatsApp `wamid` of the inbound message.
`from`	string	Sender’s phone (digits, no `+`). This is also your conversation key.
`contact_name`	string\|null	WhatsApp profile name (may be empty).
`type`	string	`text`, `image`, `video`, `audio`, `document`, `interactive` (button/list reply), `button`, `reaction`, `location`, `contacts`.
`text`	string\|null	Message text, media caption, button-tap title, or reaction emoji. `null` for media with no caption. For `location`/`contacts`, holds a JSON string.
`media`	string\|null	Direct, downloadable URL for media messages; `null` otherwise.
`media_filename`	string\|null	Stored filename (reference).
`reply_to_message_id`	string\|null	If the contact replied to a specific message, the `wamid` it replies to.
`tenant_id`	integer	Your workspace id.

Enable inbound + delivery webhooks the same way (see Webhooks Overview) — set Webhook URL and turn webhook access on. Inbound events fire automatically; no per-event toggle.

The following events still do not fire outbound webhooks:

Campaigns — campaign.started, campaign.completed, etc.
Templates — template.approved, template.rejected, etc.
Tickets and conversations — no outbound webhooks.

If you need any of these, poll the relevant API endpoint on an interval you control.

Distinguishing events

Use model + event together. For example, a contact deletion is model: "App\\Models\\Tenant\\Contact" plus event: "deleted".

function route(payload) {
  const isContact = payload.model.endsWith("\\Contact");
  const isStatus = payload.model.endsWith("\\Status");
  const isSource = payload.model.endsWith("\\Source");

  if (isContact && payload.event === "created") onContactCreated(payload.data);
  if (isContact && payload.event === "updated") onContactUpdated(payload.data);
  if (isContact && payload.event === "deleted") onContactDeleted(payload.data);
  // ... same pattern for status and source
}
