Announcing: SMS Inbound Webhooks

Pingram now supports SMS Inbound Webhooks, enabling true two-way SMS communication with your users.

The Problem

SMS is one of our most popular channel for our customers to notify their users. However, until now, developers had to build custom infrastructure to capture and process SMS replies.

Our Solution

Pingram now automatically captures and forwards SMS replies to your application:

1. Automatic conversation matching: When a user replies within 7 days of your last message, we automatically match the reply to the original conversation
2. User identification: Replies include message content, user ID, number, notification type, and even tracking ID from your original notification
3. Webhook delivery: The reply is forwarded to your configured webhook endpoint
4. Full visibility: All SMS replies are visible in your Logs dashboard

Use Cases

• Appointment confirmations: Let users reply YES or NO to confirm appointments
• Customer support: Route SMS replies to your support system
• Surveys and feedback: Collect quick responses via SMS

Getting Started

1. Navigate to Webhooks page in your dashboard
2. Enter your webhook URL and enable the SMS_INBOUND event
