With this feature, you have the flexibility to collect as much data as you want with a workflow that best suits your needs. For example, you could specify the flow of custom questions based on context or answer trees within your script.
You can format questions in specific ways (date, zip code, phone number, etc.). Also, you can check if an answer fits an expected profile. You can ask one question or many questions with each Custom Question. The core value is that the app user’s answer (or answers) for each Custom Question is saved as part of the official scan record.
To add custom questions, you can use the API or the web UI located on the Questions page and Questions tab when creating a Service. There are two options: URL and HTML. Clearly, the most flexible is the URL option. However, the HTML option is valuable if collecting data offline or if you don’t want to use your own servers.
Here are a few Custom Question (CQ) example scripts:
Here is an API doc that shows basic instructions for setting up custom questions for barcode scanning. Also, here is a PDF file that has code examples for the __SCAN_VALUE__ and __SCAN_RESPONSE__ variables.
