Question

Hello everyone, 
 
 Please share your inputs/thoughts on below use case 
 On click button/link from Appian, external web page should open with some form fields. few of them suppose to filled by data from Appian and there on users continue to work on their page can save data to their external system. (i.e. Something similar in Angular post data to web form using form inputs) 
 Is there way we can achieve this from Appian?

There is a rudimentary way of achieving it by a llowing the external web page to prefill data using URL rewriting. 
 When you are on the Appian form/view, create a safeURI link that produces a dynamic URL with prefilled data. 
 For e.g. https://externalurl?label1=value1&label2=value2 
 On click of the above link from Appian, the external page shall open with prefilled data supplied using URL rewriting. 
 
 Hope it helps.
