I already have a fully built mobile app for both Android and iOS that talks to Twilio’s APIs; SMS and voice are working perfectly. The last piece is enabling WhatsApp. All Facebook Business Manager steps, phone verification, and webhooks on my server are set, but the Twilio side still needs to be finalised so messages flow end-to-end inside the app. Here’s what I still need: • Finish the WhatsApp sender set-up in the Twilio Console and link it to my verified number • Upload/approve any required message templates so we can start with session and non-session messages immediately • Point the WhatsApp sandbox or live sender to my existing webhook URL and confirm inbound message parsing • Run a quick test from both Android and iOS builds to prove delivery and reception in real time Once this is done I expect to hit the green light in production straight away, so speed is important—I’d love to see this wrapped up ASAP. If you work regularly with Twilio WhatsApp, Facebook Business verification, and mobile push/webhook flows, you’ll find everything else is already in place and ready for you.
