How to start sending messages with Messente

Step 1 — Create your account

1. Sign up. Head to messente.com and create an account. Onboarding is self-service, so you can start immediately. New accounts include Free test credits on signup to test with.
2. Grab your keys. Open the dashboard and copy your credentials. Messente uses HTTP Basic auth with an API username and password (API keys created in the Messente dashboard).

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.messente.com/v1/omnimessage' \
  -u YOUR_MESSENTE_API_USERNAME:YOUR_MESSENTE_API_PASSWORD \
  -H 'Content-Type: application/json' \
  -d '{"to": "+37251000000", "messages": [{"channel": "sms", "text": "hello sms"}]}'

The request hits https://api.messente.com/v1/omnimessage. A 2xx response means Messentehas 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.Messente ships SDKs for Python, Node.js, PHP, Java, Ruby, C#, and Python is a great place to start.Full reference lives in the Messente documentation.
