How do I use the SMS Campaigns API?

Last updated: November 5, 2026

Use the SMS Campaigns API when you want to integrate SMS campaign creation or sending into an external system.

Before you start

  • Confirm your team has developer access and API credentials.

  • Review Whippy’s developer documentation for the SMS campaign endpoints.

  • Make sure your SMS channel, sender, and compliance setup are ready before sending through the API.

Steps

  1. Open Whippy’s developer documentation.

  2. Find the SMS Campaigns API documentation.

  3. Review the available endpoints and required request fields.

  4. Generate or locate the API credentials your integration will use.

  5. Build the integration request using the documented endpoint, authentication, and payload format.

  6. Test the request in a safe environment or with a limited audience.

  7. Review API responses and campaign results in Whippy.

Tips

  • Start with a small test before automating large sends.

  • Log API responses so errors are easier to troubleshoot.

  • Keep API credentials secure and rotate them when needed.

  • Confirm opt-in and compliance requirements before sending SMS campaigns programmatically.

Troubleshooting

  • If authentication fails, confirm the API key and authorization format.

  • If a request fails validation, compare the payload to the developer documentation.

  • If messages do not send, confirm the sender, audience, and 10DLC/compliance setup.
