Calendly V1 API and webhooks will be phasing out beginning May 2025 and will soon be permanently deprecated. Please refer to theMigration Guidefor next steps to avoid disruptions to your connections and integrations.
How to authenticate with personal access tokens
Follow the procedures below to generate a personal access token and authenticate an internal or private application with the Calendly API v2. Do not share your personal access token with public sources or reuse it across applications.
To further secure your personal access tokens, we do not display or store them in your Calendly account. After generation, they’re unretrievable.
