The WhatsApp Business API Client has certain network requirements to communicate with the WhatsApp servers.

This list might change often. It is therefore recommended you allow all outgoing traffic from port 5222 or 443, to avoid having to update this whitelist in your network each time it changes.
You will also need to allow access to our repository in JFrog where we host the container images in order to download them. You have to use hostnames for whitelisting these as IP addresses cannot be provided for them (see the Hostnames section for details).

In the event that your firewall exhibits one of these behaviors please proceed to use IP whitelisting.
The WADebug tool can help quickly check whether the coreapp container has access to all the required WhatsApp servers. With WADebug installed, simply run:
