Hi @Eric_Sackowitz, thank you for the suggestion! We do have the ability to create a resource from OPEN API/swagger schema. When you create a resource, choose Open API resource type and give it the URL of a schema, e.g. https://petstore.swagger.io/v2/swagger.json, and Retool will be pick up the operations & parameters defined when you use the resource in any app.
We could further improve this by generating/scaffolding an app from the resource schema, but that may be down the road!
