Asana Webhooks API

Asana Webhooks API allows developers to receive real-time updates about changes and events happening within Asana. By setting up webhooks, users can subscribe to specific events such as task creation, task completion, or project updates, and receive notifications in the form of HTTP POST requests. This allows for seamless integration and automation of workflows, as users can react to changes in Asana data immediately and trigger actions in external systems.

Asana Webhooks API is one of 55 APIs that Asana publishes on the APIs.io network, described by a machine-readable OpenAPI specification and an AsyncAPI event-driven specification.

The published artifact set on APIs.io includes an OpenAPI specification, an AsyncAPI specification, and API documentation.

This API exposes 5 operations across 2 paths, and defines 10 schemas. It is described by OpenAPI 3.2.0, at version 1.0.

Requests are made against a single base URL, https://app.asana.com/api/1.0.

Where this information came from

This is an independent, third-party profile of Asana Webhooks API, 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.
