To clarify, our Rx Refill API is "inbound" in nature only. If the patient initiates a refill, one can be completed. This is not an API around "outbound" information from Walgreens systems. Hope that helps to clarify.
We have over 100 integrated apps with our photo printing API and offer a revenue share of up to 20% on the order once it's sold. Over 8200 locations in the US and many different photo products (https://developer.walgreens.com/page/quickprints-product-inf...).
We have a very simple API. We are not sending back any Rx info. You send us the Walgreens Rx and we present back a select store and time checkout. No customer name. No medication info.
If anyone wants to learn more about the various APIs that Walgreens offers, I run the program and can help out. Just drop a note to [email protected] or tweet us at @WalgreensAPI. We have photo printing, the aforementioned Rx refill and a tie-in with our rewards program and fitness apps/wearables.
