Basically I’d like to make an app for an alcohol delivery service. Does Open Id Connect allow for age verification?
I have no knowledge of how Open ID Connect works, but I assume it is API-based. Appsheet cannot receive responses from the webhooks it sends out. What you want is probably impossible to accomplish with just the Appsheet platform, however it may be possible by utilizing a Google App Script (or equivalent) in conjunction with an Appsheet app.
