Supercharging Webhooks

December 03, 2020
For the week of November 9th, we did something a little different. I teamed up with Shyamal Ruparel, Developer Evangelist at Contentful to build an application that used Courier and Contentful during our respective live streams. We started on the ContentfulDevs stream on November 10th and finished the next day on the Courier Live stream.
During these two hour-long sessions, we updated Shy's existing Henshin blog that he created using Python, Flask, and Contentful to allow readers to subscribe to post updates. We used the Courier Lists API to add readers to lists based on blog tags. We then set up Contentful Webhooks to send to the list, specified by tag, using Courier when new posts were published.
Check out the videos below to watch us:
- Add the Subscribe UI to the existing blog
- Use a Flask route and the Courier Python SDK to add the user to a list
- Add the ability to unsubscribe
- Set up a Contentful Webhook and connect it to a Flask Route
- Send to a Courier List using the payload from the Contentful Webhook
- Create a Courier Notification that uses data from Contentful
Check out the full project code available on GitHub.
Be sure to Like the video and Subscribe to our YouTube channel.
Is there something you’d like to see us do using Courier? Let us know and it might be the subject of our next Courier Live. We stream a new Courier Live every Wednesday at 12 pm PT (3 pm ET). Follow us on Twitch to be notified when we go live.

Customer Engagement Platforms Are Splintered. Message Orchestration Is the Fix
Customer engagement platforms are splintered. Some are built for campaigns, others for support automation, and others treat messaging as a transactional delivery problem. The result is collisions, blind spots, and message fatigue. The highest-leverage fix is solving the lifecycle-to-product and transactional vector with a message orchestration layer: one system that routes, suppresses, prioritizes, and observes messages across channels. Think air traffic control for user communications.

What are transactional notifications? Transactional email examples, transactional push, and more.
Transactional notifications are automated messages triggered by user actions or system events, like password resets, order confirmations, and payment alerts. Unlike marketing messages, they require no opt-in and have legal protections under CAN-SPAM. This guide covers what transactional notifications are, how they work across email, SMS, and push channels, real-world examples for each, and how to stay compliant. Whether you're building your first notification system or auditing an existing one, this breakdown will help you understand what belongs in each category and how to route messages correctly.
