0:00 Once we fulfilled the cake order and everything was ready to pick it up.
0:03 The way we wanted to let our users know was we sent them a message back
0:07 to the same place they started this conversation,
0:09 which was through WhatsApp. This was a little bit different,
0:12 though, Instead of responding to some kind of inbound message,
0:15 which is what happens at Twilio studio with our flow,
0:18 we're going to initiate a message,
0:20 so we're going to just simply specify our from number.
0:24 This would be your business number or something like that.
0:27 But here, this is the sandbox number.
0:29 The to number is whatever they initiated their call from so ordered.user.phone
0:34 and we give them some message like your cakes order status code is ready for pickup
0:38 create a rest_client set the id set the password again coming from our secrets
0:44 and we just say client messages create body, to, from.
0:49 Of It goes long as there's no erro message,
0:51 things are good. One thing to keep in mind is if this is outside the
0:54 24 hour interaction window, which in this case it probably is you're going to need
0:59 to make sure that you're using one of these rebuilt couple of templates that you can
1:03 use. See the URL, the bottom.
1:04 You can learn more about that.
1:05 And then when you get this set up for real,
1:08 you're going to need to get the message template approved at WhatsApp,
1:11 so that then you can send that we'll be sure to use the right message template
1:15 to make sure that this will go through for them and doesn't get blocked.
1:18 That's it. Now our user has gone round tripped.
1:21 They've started the cake conversation with us.
1:23 We told him what we had.
1:25 They filled out all the information,
1:26 requested the cake, we got it over and flask.
1:29 The admin API showed it to the Bakers.
1:31 They baked it. And now we send them the message and they come and pick
1:35 up the cake. Fantastic app we built here, isn't it?.
