Courier

Courier is notification infrastructure for product and engineering teams - a single API that orchestrates transactional and product messaging across email, SMS, push, chat (Slack, Teams), and an in-app inbox. One Send call routes a notification to the right channel(s) per recipient using templates designed in a visual studio, subscription topics, user preferences, brands, audiences, and automation workflows. The REST API (base https://api.courier.com) also manages users/profiles, lists, tenants for multi-tenant apps, translations, bulk sends, and audit events, and is wrapped by official server SDKs (Node, Python, Go, Ruby, PHP, Java) and a CLI.

Courier publishes 14 APIs on the APIs.io network, including Audiences API, Audit Events API, Automations API, and 11 more. Tagged areas include Notifications, Messaging, Email, SMS, and Push.

Courier’s developer surface includes authentication, documentation, engineering blog, and 9 more developer resources.

Where this information came from

This is an independent, third-party profile of Courier, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
