Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Confirm the account has a Premium subscription (Silver, Gold, or Platinum), since the free tier has no API access
Generate an API key from the Tools section of the SignUpGenius account
Authenticate REST requests with the key per the developer.signupgenius.com reference
Call endpoints to pull sign-up sheets, slots, and participant/volunteer data as JSON
Track your daily call volume against the plan's ceiling to avoid being throttled
Known gotchas
Daily call limits differ sharply by plan tier - a few calls/day on Silver versus up to 5,000/day on Gold/Platinum
The API is oriented around pulling your own account's data, not general third-party automation of other users' sheets
Free-tier accounts have no API access at all, which is a common surprise during integration scoping
