Python-powered chat apps with Twilio and SendGrid Course
Source code and course GitHub repositorygithub.com/talkpython/twilio-and-sendgrid-python-course
What's this course about and how is it different?
Many courses will show you a quick how-to with Twilio. In this free course, we will build a complete, end-to-end Flask web application with modern Python tools. You will learn exactly what is needed to truly integrate text/chat with Python. We'll sketch out the workflow in Twilio Studio and then create a series of HTTP/ JSON APIs in Flask that perform key integration.
We will add text-intiated ordering for a hypothetical bakery called "Cloud City Cake Company". Over at the Cloud City website, we'll have a quick way to kick off a chat conversation in WhatsApp, hook important stages of that conversation with our Flask APIs, send rich emails and generate PDFs in Python.
Our customers will receive an email invoice as well an unprompted text message when their cake is ready for pickup. At the same time, this integration will communicate with our bakers about what cakes have been ordered and they can indicate when the cakes are finished.
What we'll build
Here is a visual summary of just some of what you'll build during this course:
- A Twilio chat interaction over WhatsApp with validation and API integration
- Rich email response over SendGrid with formatted HTML, images, and attached generated PDF
- A Flask admin backend to recieve the orders and notify users over chat their order is ready

Who is this course for?
This course is for anyone who wants to build Twilio chat applications with Python as the backend language. The student requirements are quite light for this course. You'll need Basic Python language knowledge:
- Basic Python language experience
- Understanding of web applications (we'll talk through the Flask details)
Note: All Twilio and SendGrid services used in this course are based on free trial accounts. You won't have to subscribe to anything.
Concepts backed by concise visuals
While exploring a topic interactively with demos and live code is very engaging, it can mean losing the forest for the trees. That's why when we hit a new topic, we stop and discuss it with concise and clear visuals.
Here's an example of calling out the API for sending an outbound WhatsApp message with the Python Twilio library.
