How to start sending messages with SmsManager

Step 1 — Create your account

1. Sign up. Head to smsmanager.com and create an account. Onboarding is self-service, so you can start immediately. New accounts include free trial credit to test with.
2. Grab your keys. Open the dashboard and copy your credentials. SmsManager uses API key passed in the x-api-key request header on all endpoints (an apikey query parameter is accepted only on GET /simple/message).
3. (Optional) Use the sandbox. SmsManager 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://api.smsmngr.com/v2/message \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"body": "Hello from SmsManager!", "to": [{"phone_number": "420777123456"}]}'

The request hits https://api.smsmngr.com/v2/message. A 2xx response means SmsManagerhas 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.SmsManager ships SDKs for JavaScript/TypeScript, PHP.Full reference lives in the SmsManager documentation.
