Using KoboToolbox for Real-Time Financial Data Validation

Hello everyone,

I’m designing a KoboToolbox form for a survey project, and part of the workflow involves users verifying their account balances for eligibility checks. We’re considering integrating FAB Bank balance inquiry via an API so participants can confirm their balances directly within the form.

I’d love advice on a few points:

  • Has anyone successfully linked external APIs to KoboToolbox forms for dynamic data validation?
  • What’s the best practice for storing or masking sensitive data when using such APIs?
  • Are there existing scripts or tools recommended for safely fetching financial information without impacting form performance?

Any tips, code snippets, or references would be really helpful. I want to make sure the form remains user-friendly while handling sensitive financial data responsibly.
