We’ve also made a video tutorial to guide you through the process.

Setup

  1. Create a Sinch developer account
  2. In the dashboard, click “Apps” in the left-hand menu
  3. Click “Create new app”
  4. Give your app a name and click “Create”
  5. Keep your app key and secret safe as you will need this in a minute
  6. Open your terminal

Sending the SMS via the API

Then, in the cURL command, add the phone number and message you want to send, and add your app key and secret. Once you are finished, you should have something that looks like this:

curl --user "application\\your_app_key:your_app_secret" --data '{"message":"your_message"}' -H 'Content-Type: application/json' https://messagingapi.sinch.com/v1/sms/the_phone_number

Copy and paste this into your terminal, wait a few seconds, and you should receive the SMS message to the phone number you added in the command.
