During our August 19th Courier Live, Tony Nguyen from our engineering team joined me to talk about my favorite Courier feature, the logs. We presented a high level overview of the logs and dove into the details of each timeline event in the Courier Application. We then covered how you could retrieve the same information using the Messages API.
Check out the video below to watch us:
While Courier provides a great graphical experience for viewing their logs, sometimes you need to be able to grab that information as part of a backend process. This can be done using the Messages API.
You can retrieve a pageable list of log messages using GET /messages.

curl --request GET \--url https://api.courier.com/messages \--header 'authorization: Bearer <AUTH_TOKEN>'
Once you have a messageId, either from the call above or the response of a send call, you can use it to get more details using GET /messages/{message_id}.

curl --request GET \--url https://api.courier.com/messages/1-5f3d7aa7-e4b8f9ba9a4672ba5d46754c \--header 'authorization: Bearer <AUTH_TOKEN>'
If you would like to retrieve the details provided in the log details timeline, you can use GET /messages/{message_id}/history.

curl --request GET \--url https://api.courier.com/messages/1-5f3d7aa7-e4b8f9ba9a4672ba5d46754c/history \--header 'authorization: Bearer <AUTH_TOKEN>'
You can learn more about the Courier API from the Courier API Reference Documentation.
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 noon Pacific. Follow us on Twitch to be notified when we go live.

Customer Engagement Platform vs CRM: Key Differences Explained
A CRM stores customer data: contacts, purchases, support tickets, and pipeline. It answers "who are our customers?" A customer engagement platform (CEP) orchestrates communication across email, push, SMS, in-app, and chat. It answers "what should we tell them next?" CRMs focus on historical records. CEPs process real-time behavior and trigger messages based on actions. Most teams need both, plus a third layer: notification infrastructure for reliable multi-channel delivery. Courier bridges CEP and infrastructure by combining routing, failover, and delivery tracking with engagement features like preference management, visual templates, and in-app notification centers.

How We Investigate Support Tickets at Courier
Courier's support team resolves complex issues 4X faster using parallel investigation. Here's how it works: when a ticket comes in, an AI agent starts exploring the codebase while the support engineer examines actual customer data. The agent traces code paths and searches past investigations. The human reads event logs and forms hypotheses based on real state. Running both simultaneously catches mismatches fast—the agent sees what could cause a problem, the human sees what actually happened. This post breaks down the workflow, tools, and documentation structure that makes it repeatable.
