Request an integration. ------------------------ Tell us the app and what you want it to do. Requests land with the team as a conversation, not a form in a void, and they decide what we build next. We email you if it ships. Which app? What should it do? Email Leave this field empty Send request FAQ Integration questions, answered ------------------------------- ### Does AddCal integrate with my app? Almost always, through one of three routes. A few apps have a native AddCal integration. Any of the 8,000 apps on Zapier can create AddCal events and receive RSVPs through the AddCal Zapier app. And because an add-to-calendar link is just a URL, you can paste one into any email tool, website builder or CMS with no integration at all. ### Do I need Zapier to connect AddCal to other tools? No. Zapier is the no-code route, but Smart Links turn a URL you build in any tool into an event, the REST API works from any language, and webhooks push RSVPs to your own endpoint. n8n and Make work through the API with no custom node. ### Which plan do I need for integrations? Add-to-calendar links, embeds and the REST API are on every plan, including Free. The Zapier app and Smart Links start on Premium. Webhooks and Dynamic Links are on Business. Each integration page lists what it needs. ### Is there an API? Yes. The REST API creates and updates events, calendars and RSVPs with a personal access token, and there is an MCP server so AI assistants such as Claude and ChatGPT can work with your calendars directly. Both are documented under Documentation. ### How do I request an integration? Use the request form at the bottom of this page. Tell us the app and what you want it to do. Requests go straight to the team and shape what we build next, and we email you if it ships. Still have questions? A real person on our team replies, usually the same business day.
