I have more than one request to integrate MDCwith WhatsApp. I never developed an app with nodejs/graphql, so I’m still investigating the possibilities. So far I’ve seen a couple of external WA services (eg. picky assist and wati.io integrate with Zapier, getnick.io integrates with Integromat and Zapier) which could be used to set up a convenient workaround.
If you have some advice it would be welcome.
