Authentication
From SimplyMeet.me
The SimplyMeet.me API uses API keys to authenticate requests. You can generate (and block previously generated) your API keys in the SimplyMeet.me Integrations if you have a paid plan. 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.
To test requests using your account, replace the <your_api_key>
API key with your actual API key
curl -H "X-API-KEY: <your_api_key>" https://secure.simplymeet.me/api/users/me/meeting-types
