Im wanting to have a downloadable warranty

I have just about finished the app but the last part i was wanting a customer using it to be able to put in details that are needed then they press a button and those details are put into a warranty which they can then download. I have spent hours and hours trying to do it with google sheets but im at a total dead end. Its only some simple info, name, address date and an invoice number but i cant get it to work. I have tried as a data source but cant seem to have the correct block’s or suss which ones i need

Hope someone can help thanks

I’ve used Docsfold for that. It’s a small company but the developer is quite responsive to messages.

Have you tried using the “share message” function? It’s only plain text but you can include invoice number, name, as variables and join them into as single message using the JOIN function. The user can then save it to their Notes or whatever app they choose.
