Is it possible in Apps to do a written signature on a mobile phone and store the signature in a variable that is passed to a process - and from there replacing a placeholder image in a word document?
I think it’s possible. If not in Apps then using DataService. However I will not recommend such thing from security reason. It’s the same case where you could keep password in string type variable which is one of the worst thing you may do.
The signature should be passed as an image variable and used to replace a picture in a word document and afterward send to the person that did the signature. As a confirmation that the customer has been informed of something. Does it make sense?
