I just strated looking at the offers API and I have a customer who wants to reward people who shop anywhere in an area. Do you have to specify a specific merchant or can we get notified for every transaction a user makes?
Apologies for getting back to you with delay. Which API you are intrested to consume from offers? Please provide more details about the usecase such as user journey and how do you wish to provide this service to the merchant.
The Visa offers documentation is at : https://developer.visa.com/legacy/downloads/VOP_Offer_API_August_2016.pdf
For development and testing, after creating your project in the SandBox dashboard, add the Visa Offers API by clicking on Add APIs.
