How to start sending messages with CM.com

Step 1 — Create your account

1. Sign up. Head to www.cm.com/ and create an account. Onboarding is self-service, so you can start immediately.
2. Grab your keys. Open the dashboard and copy your credentials. CM.com uses Product token passed in the X-CM-PRODUCTTOKEN HTTP header (obtained from the Channels app); requests must use TLS 1.2+..
3. (Optional) Use the sandbox. CM.com offers a test environment, so you can validate your integration before sending live traffic.

Step 2 — Send your first SMS

The fastest path is a single API call. Drop in your credentials and a destination number, then run this from your terminal:

curl -X POST https://gw.messaging.cm.com/v1.0/message \
  -H 'accept: application/json' \
  -H 'content-type: application/json' \
  -H 'X-CM-PRODUCTTOKEN: <YOUR_PRODUCT_TOKEN>' \
  --data-raw '{
    "messages": {
      "msg": [{
        "from": "Sender",
        "to": [{"number": "00447911123456"}],
        "body": {"type": "auto", "content": "My first CM.com message"},
        "reference": "my_reference_123"
      }]
    }
  }'

The request hits https://gw.messaging.cm.com/v1.0/message. A 2xx response means CM.comhas accepted your message for delivery — you should see it arrive within seconds.

Step 3 — Go native with an SDK

Once the raw call works, switch to an official SDK for retries, typing and error handling.CM.com ships SDKs for PHP, Java, Python, .NET, Node.js, and PHP is a great place to start.Full reference lives in the CM.com documentation.
