What survey platform does Reaply use to collect responses?

We currently don't have a survey creation functionality in this version. You can use any survey platform you like and connect it to your Reaply project. All you need is a link to your survey, provided you can customise the url to include placeholder query for "&respondentId=". It's the same link you might create if you were working with a Panel Provider. Here's an example of a compatible survey link: https://www.dooblocawi.com/client/Survey.aspx?Ticket=OV3K0KT9&respondentId=. 

Your survey will load inside the agent's app when they administer the interviews.
