How to start sending messages with SendPulse

Step 1 — Create your account

1. Sign up. Head to sendpulse.com and create an account. Onboarding is self-service, so you can start immediately. New accounts include Free plan (15,000 emails/mo) + 10 test SMS to test with.
2. Grab your keys. Open the dashboard and copy your credentials. SendPulse uses OAuth2 client_credentials: POST client_id/client_secret to https://api.sendpulse.com/oauth/access_token to receive a 1-hour Bearer token (or use a static API key from account settings), then send it as 'Authorization: Bearer <token>'..

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.sendpulse.com/sms/send \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "sender": "SenderName",
    "phones": ["380931258293"],
    "body": "Hello from SendPulse"
  }'

The request hits https://api.sendpulse.com/sms/send. A 2xx response means SendPulsehas 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.SendPulse ships SDKs for PHP, Python, Ruby, Java, Node.js, C#, and PHP is a great place to start.Full reference lives in the SendPulse documentation.
