Webhook about Changing WhatsApp Template Category

Last updated: 15 June 2026

This webhook enables you to access information regarding changes to the category of WhatsApp templates. When a change is made, edna Pulse sends an HTTP POST request to your system's specified URL. This article describes the webhook format and transmitted data.

Configuring the URL

To set the URL for the WhatsApp template category modification webhook, send a POST request to the URL https://app.edna.io/api/callback/set .

Setting URLs for Webhooks

tip

Your URL should be genuine and accessible to the public via the internet. Only use the secure HTTPS protocol — the default is TCP port 443. URLs can contain a maximum of 500 characters.

info

If a webhook delivery fails, edna Pulse will attempt to resend it up to three times using a backoff scheme: 4, 128, and 2048 seconds after the previous attempt.

You can also specify the webhook URL in your edna Pulse account: Integration → Settings → Main profile → Webhook URL for WhatsApp template category changes.
