How to start sending messages with Infobip

Infobip is a privately held communications platform based in Vodnjan, Croatia (EU). This guide takes you from zero to a delivered SMSin about five minutes — no sales call required.

Before you start
  • A Infobip account — sign up here (free trial credit included).
  • Your API credentials from the dashboard.
  • A phone number capable of receiving SMSs for testing.

Step 1 — Create your account

  1. Sign up. Head to www.infobip.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. Infobip uses API key auth via the 'Authorization: App {api_key}' header.
  3. (Optional) Use the sandbox. Infobip 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://xxxxxx.api.infobip.com/sms/2/text/advanced' \
  -H 'Authorization: App YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json' \
  -d '{"messages":[{"from":"InfoSMS","destinations":[{"to":"15551234567"}],"text":"Hello from Infobip"}]}'

The request hits https://{base_url}.api.infobip.com/sms/2/text/advanced. A 2xx response means Infobiphas 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.Infobip ships SDKs for Java, C#, Python, PHP, Go, Node.js, and Node.js is a great place to start.Full reference lives in the Infobip documentation.

What's next

  • Add more channels. Infobip also supports WhatsApp, RCS, Viber, Voice — reuse the same account and credentials.
  • Mind compliance. Infobip is GDPR, ISO 27001, SOC 2, HIPAA aligned, with EU and US data residency options.
  • Compare before you commit. See how Infobip stacks up on the provider table or in a head-to-head comparison.
