Visa Issuer Measurement is a channel for accessing an issuer’s portfolio performance trends. The Visa Issuer Measurement API is essentially a portfolio diagnostics platform that delivers insightful and analytical data of card usage. The API supports retrieval of crucial metrics on the basis of a variety of parameters including account funding source, currency, country, month, and product. The API sends requests in JSON format. The API’s production environment is restricted to approved partners.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
