Can I directly send message to recipient using Twilio WhatsApp api without using join [key-word].

Is it because of Twilio Sandbox?

If I send request to enable my Twilio number of WhatsApp, issue will get resolved and I can send messages directly?

The join [key-word] system is just for the Twilio Sandbox for WhatsApp. It allows Twilio to use one WhatsApp number for all accounts that are testing with the Sandbox.

Once you have connected your Twilio number to your WhatsApp business profile you will be able to send messages to your users without requiring them to message you first. Note that WhatsApp does still require an explicit opt-in from your users before you can send to them. Also, for initiating conversations you will need to get template messages approved and then use the template as the first message. But the technical barrier of the join message will not be in your way.

  • Also, when you initiate, you would use one of your pre-approved templates to do so. – Alan Mar 23 '22 at 23:19
  • Ah, very good point, thanks Alan! I'll add that to the answer. – philnash Mar 23 '22 at 23:31
  • Philnash and Alan Thanks for your help. I want some clarification on "WhatsApp does still require an explicit opt-in from your users" This I have to handle on my code level. I mean using web hook I have to store the service "Start" or "Stop" response of the recipient? or this is internally handled by WhatsApp? – Gaurav Narkar Mar 24 '22 at 06:19
  • The opt-in is not code, as such, but that you cannot just send messages to your users without getting their permission first. If you [click through the link to the information on the opt-in](https://developers.facebook.com/docs/whatsapp/overview/getting-opt-in) you will see WhatsApp's requirements. – philnash Mar 24 '22 at 06:21
