Canny API
Provides a REST API for managing user feedback posts, votes, comments, and changelogs on the Canny platform, enabling agents to automate feedback collection, triage, and product roadmap workflows.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Passing API keys in the POST body is a security antipattern — keys are likely to appear in server access logs and HTTP debugging tools. No scope granularity. SOC2 Type II certified.
⚡ Reliability
Best When
An agent needs to bridge product feedback from multiple customer touchpoints (support, sales, surveys) into a centralized voting board and keep post statuses synchronized with engineering progress.
Avoid When
You need real-time or in-session feedback capture; Canny is designed for asynchronous, structured feature request management.
Use Cases
- • Automatically create feedback posts from support tickets, survey responses, or sales call notes to centralize product feedback
- • Retrieve top-voted feature requests filtered by customer segment to prioritize roadmap decisions with usage data
- • Update post status (under review, planned, complete) when corresponding engineering tickets are merged or released
- • Sync user and vote data to a data warehouse for cross-referencing feedback with revenue and usage metrics
- • Post changelog entries automatically when new features ship to notify subscribed users of updates
Not For
- • Real-time user feedback collection during active sessions — Canny is asynchronous and forum-style, not a live feedback widget
- • Qualitative UX research or session recording; Canny captures structured feature requests, not open-ended research
- • Teams needing private internal feedback tools; Canny's default model is public-facing customer voting boards
Interface
Authentication
API key passed as apiKey field in POST body (not a header). This unconventional pattern means API keys can appear in request logs. No scope granularity — all keys provide full account access.
Pricing
Free tier is genuinely useful for small teams. API access is not paywalled. Credit card not required to start.
Agent Metadata
Known Gotchas
- ⚠ API keys are passed in the POST body rather than as a header, which is atypical and means keys will appear in HTTP access logs unless the server explicitly filters body content
- ⚠ Creating a vote for a user requires the user to already exist in Canny; agents must create or retrieve the user record before creating their vote
- ⚠ The API does not support bulk operations — creating posts or votes for large numbers of users requires individual API calls with appropriate rate management
- ⚠ Webhook event types are limited; not all post state changes trigger webhooks, so agents may need to poll for status changes on longer workflows
- ⚠ Offset-based pagination can return duplicate or missed records if posts are created or deleted during pagination — use with caution in high-activity boards
