Why developers choose 1MSG

The production backend for your WhatsApp API, built in, so you don't have to build it yourself.

Message history

Full history via GET /messages. For support and CRM sync.

Meta Cloud API has no message history. You get webhooks and store everything yourself. 1MSG keeps every sent and received message and returns it with one call, filtered by chat or time.

GET https://api.1msg.io/{channelId}/messages?limit=20&[email protected]

{ "messages": [ {
  "messageNumber": 1,
  "id": "0XzkmGNn4prUAQlzsHApGNRXQ0U",
  "body": "Test message",
  "fromMe": true,
  "chatId": "[email protected]",
  "type": "chat",
  "time": 1665396610
} ] }

Delivery log

Delivery status via GET /hookInfo: sent, delivered, read, failed.

In Cloud API, a delivery status exists only as a webhook. Miss it, and it's gone. 1MSG keeps the full status history for every message, so you can check sent, delivered, read or failed at any time, even if your server was down.

GET https://api.1msg.io/{channelId}/hookInfo?messageId=gBGGeSaGViBfAgnlzOSHEwK9O6F

{ "hooks": [
  { "type": "message", "status": "sent", "timestamp": "1654864094", "recipient_id": "556123122026" },
  { "type": "message", "status": "delivered", "timestamp": "1654864096", "recipient_id": "556123122026" },
  { "type": "message", "status": "read", "timestamp": "1654864310", "recipient_id": "556123122026" }
] }

Observability [SOON]

Request and response history to debug integrations in one place.

Meta gives you totals and dashboards. 1MSG shows the health of every webhook today, with full request and response history coming soon.

GET https://api.1msg.io/{channelId}/settings

{
  "webhookUrl": "https://example.com/webhook",
  "haveDisabledWebhooks": false,
  "webhookStatuses": [
    { "url": "https://example.com/webhook", "circuitState": "ok" }
  ]
}
