The SimplyMeet.me API uses API keys to authenticate requests. You can view your API key in the SimplyMeet.me Integrations. API requests without authentication will fail. Do not share your secret API keys in publicly accessible areas such as GitHub, client-side code, and so forth. Add your API key to the X-API-KEY header to get the access to the API endpoints.
