Send an Outbound SMS

In this SMS API Quickstart, you'll learn how to send an SMS from your web application using the SMS API.

Step 1: Sign up for free

Before we get started, log in to the MessageBird Connectivity Platform and collect your live API key from the Developer Dashboard.

Step 2: Send your first SMS

Next, enter your credentials and mobile number - as both the originator and recipient - to the snippet below and copy it to your terminal.

curl -X POST \
-H 'Authorization: AccessKey YOUR-API-KEY' \
-d "recipients=+31XXXXXXXXX" \
-d "originator=+31XXXXXXXXX" \
-d "body=Hi! This is your first message."

Next, simply hit enter in your terminal.

Good job! You’ve sent your first SMS with the MessageBird SMS API using cURL!

Step 3: View the response

Now, let’s view MessageBird’s HTTP response to your API call. If the set up was correct, you'll receive a response similar to this:

"id": "9a9c83bc90d34a49b57fbc79e33bc5cd",
"href": "",
"direction": "mt",
"type": "sms",
"originator": "31XXXXXXXXX",
"body": "Hi! This is your first message.",
"reference": null,
"validity": null,
"gateway": 10,
"typeDetails": {},
"datacoding": "plain",
"mclass": 1,
"scheduledDatetime": null,

"items": [
"recipient": 31XXXXXXXXX,
"status": "sent",
"statusDatetime": "2019-02-19T11:56:17+00:00"

If something went wrong, you’ll receive an error response from the MessageBird API. Don't worry, simply head over to the SMS API Troubleshooting to understand the error.
