Transactional Text Messaging API

A straightforward HTTP interface for standard or personalized text messages, built for transactional notifications where speed and reliability matter. POST a JSON request with three parameters:

• from: your short code, toll-free number, or 10-digit long code
• to: the recipient’s mobile number, with country code
• message-text: the text of your message

Optional parameters check that the recipient is subscribed to a campaign, replace links with tracked short links, and report delivery through postbacks.

Common uses: two-factor authentication and verification codes, appointment and billing reminders, delivery updates and order confirmations, receipts, account alerts, promotional offers, and customer service follow-ups.

Send SMS request example

curl -X POST \
     -H "x-api-key: YOUR_API_KEY" \
     -H "content-type: application/json" -d '
      ' \
  "YOUR_API_URL"

Send images, video, audio, GIFs, contact cards, and calendar invites directly to your customers’ phones.
