Infobip lets you communicate with customers on SMS, WhatsApp, Email, Voice, Viber, RCS, Apple Messages for Business, and other channels, from one account. You can work in the web interface without code, through the API, or through an AI agent.

To start, create a free account, send a test message from a shared test sender, and confirm that it was delivered. Then go live to send to real customers.

On a self-signup account:

Free trial with credits for each channel
No payment details to sign up
Shared test senders to start sending

From sign-up to production

Follow these steps, from the main concepts to sending to real customers:

Understand how the platform works
Accounts, channels, senders, and how message delivery works.

Create an account
Sign up, verify your email and phone number, and choose the channel to try first.

Understand the free trial
What the trial includes, its limits, and who you can send to.

Send your first message
Send a test message from the web interface or through the API, and confirm that it was delivered.

Go live
Get your own sender, move to a paying account, and send to real customers.

LEARN MORE

Does your company already have an account? A colleague with the Account admin role, or your account manager, adds you. Then log in.

Do you have a team, or several brands or customers? Set up your account structure, and then add users and assign roles.

Send an SMS through the API

Send your first SMS through the API, with the API key and base URL from your account. During the free trial, send from the shared test sender InfoSMS. On a self-signup account, send to a verified recipient. Replace {baseUrl} with your base URL, {authorization} with App followed by your API key, and {your-phone-number} with the number you send to.

A response with a messageId means the message was accepted for processing, not that it was delivered. See Accepted does not mean delivered.

Some channels and countries need a registered sender before you send to real customers. See Get your own sender in Go live. To send without code, use Broadcast in the web interface. See Send your first message.

To send through an AI agent instead, connect an AI tool, such as Claude or Cursor, through MCP. Then describe what you want in plain language. See Build with AI agents.
