We can definitely look into this feature request! You want a way to run a query or API call to Retool's backend that would replace the wallet key on an existing Oracle DB resource for one specific app, correct?
I am curious, is this functionality outside the scope of a refresh flow for the resource? How are you getting the new wallet key when the old one expires?
Could you share a screenshot of how your Oracle resource is set up? I am not familiar with using Wallet Key files but I can definitely make a feature request for having an API endpoint to update the resource with a new file.
How are you imagining the event for updating the file to be triggered?
