When we received an order through WhatsApp and called into our API, we wanted to send a receipt to let the users know.
0:08
Here's your official receipt for purchasing our cake. So what we're gonna do is you send grid another Twilio service to send it.

So what we do is we create a dictionary that's going to allow us to pass data over to a Jinja template.
0:21
Remember, we could do all sorts of things to come up with that HTML. But a really flexible thing is suggest leverage Jinja to actually generate those.
0:30
And in order for Jinja to work, give it a dictionary of values and it can dynamically generate the HTML just like it
0:36
does in the Web itself. We got our HTML text will create the Send Grid API client. We pass over the API Key,
0:44
which were storing secretly. Remember that our secrets.json, we create 'from' 'to' and subject
0:50
object, passing over our information. The to is order.users.email, following that
0:55
SQLAlchemy relationship. But our HTML content we're going to generate our text content by
1:01
just mark down file our HTML content and then we're gonna create our mail message with a sendgrid mail class. Just pass all the items over.
1:10
Go to the clients they send when you get a response. And as long as the response.status_code is 200, 201 or 202 we're all good. If it's something else,
1:18
we're gonna say there's an error and that's it. Incredibly simple to send a really nice email and in practice, remember, we also created an attachment,
1:27
pdf attachment, and we attached that as well. So really powerful email system here with Sendgrid.
