Actually, the GraphQL API support in FreePBX is moving rapidly right now. I would actually recommend running edge for a few of the modules if you want support. Keep in mind the APIs are still subject to change as we work through issues. To install Full GraphQL support make sure you run the following daily until the API stabilizes: fwconsole ma upgrade --edge framework api certman firewall sysadmin
Like I said above, you need to upgrade framework, api, certman, firewall, and sysadmin to the latest version in EDGE for them to run properly. Simply upgrading the API module to the latest stable version won’t make it work.
Execute the following command in the CLI: fwconsole ma upgrade --edge framework api certman firewall sysadmin
