Came across the following service on 1 of the indie hackers email updates. It offers a variety of services for your data, including exposing a mysql db as rest API.
This is Steve at Phiona. Glad to hear you’re considering us for exposing your MySQL database through REST API! Happy to walk you through the tool by video chat if you’d like to see if it meets your specific use case.
Because I really have not thought of it in this way. Cannot believe it is so obvious. Have a param or 2 for your authentication and then others for the values you pass to the db. Makes total sense. Thanks @AdrianoLuiz and @Teodor. Although AppGyver looks incredible just to try out as well. Thanks @max_gb.
