Set multiple webhooks for Phone Number

It is only useful in certain non-standard situations. To set up a webhook in a standard way please refer to this article.

You can attach multiple Webhook URLs to a single phone number. This can be used to manage additional webhooks, enhancing automation and integration capabilities within your systems. This feature compromises on performance. The more webhooks are attached to a number, the longer messages will take to arrive and be acknowledged, so the overall performance will be impacted. Using only one webhook is recommended for high volume accounts.

All destinations will get cloned incoming notifications from the Messaging API. But, extra webhooks will only get these notifications if the main destination (connected to the phone number) successfully receives them with 200 success code. See our documentation for Best Practices for designing Integrations.

Each phone number is limited to a maximum of 3 unique webhooks. This limit cannot be increased. You cannot attach multiple webhooks to a full WABA, only to specific phone numbers.

Webhook URLs or headers for Cloud API does not support "_"(underscore) or ":xxxx"(port)in (sub)domain names.

Invalid webhook URL: https://your_webhook.example.com Valid webhook URL: https://yourwebhook.example.com

Invalid webhook URL:https://subdomain.your_webhook.example.com:3000 Valid webhook URL: https://subdomain.yourwebhook.example.com
