I am writing my application, and I need to integrate Query API for mVisa, however the sandbox available on the website doesn't allow to test it, and no test data is available for it, I want to make sure that I am using the correct URI, I am testing using my app and postman but doesn't get a response, I want to ask is there any way to test the QueryAPI through Visa test system or any specific test data, because I always receive error 404. Following is the URI I am using
when I remove the acquiringBin part, it does respond me with error that this is a mandatory field, however when I use it, all I get is empty body and this header
Before you continue to learn more about Visa Direct and work with its mVisa APIs, it's important to review the Visa Direct documentation via this link - https://developer.visa.com/capabilities/visa_direct/docs
Particularly, please read the top few paragraphs that are highlighted in yellow that discuss requirements to use Visa Direct APIs.
After reading this documentation, if you meet the requirements, click through the link in those paragraphs to the Visa Direct Program Implementation Questionnaire, fill it out, and submit the questionnaire to the email address listed on that form.
