You can find the API endpoint for your Ragic form or entry by passing api as a query string parameter to specify this is an API request.
https://www.ragic.com/<account>/<tab folder>/<sheet Index>/<record id>?v=3&api
Please Note:
It's a good practice to specify the API version every time you send your request to ensure a correct version. If the version is not specified, the latest version will be used, but unexpected changes to the API may cause problems in your application.
For example if you usually access your Ragic form using the following URL:
https://www.ragic.com/demo/sales/1
Its HTTP API endpoint URL would be:
https://www.ragic.com/demo/sales/1?v=3&api
Or for a single entry in your form, you would include an id (for example record id of 1) to specify an entry:
https://www.ragic.com/demo/sales/1/1
Its corresponding HTTP API endpoint URL is simply:
https://www.ragic.com/demo/sales/1/1?v=3&api
