Walgreens opened parts of its retail and pharmacy systems to outside developers through an API program launched in 2012 and expanded in 2013. The first integrations sent photos from apps such as Instagram to Walgreens for same-day store pickup; a later prescription API let compatible apps scan a bottle barcode and request a refill. The program connected digital intent to a physical Walgreens transaction rather than moving every step into the partner app.
What Walgreens actually opened
The initiative exposed selected Walgreens capabilities through interfaces that third-party developers could place in their own websites or mobile apps. It was not unrestricted access to Walgreens systems. Each integration had to use the documented API, satisfy Walgreens’ operational requirements and ultimately depend on a Walgreens store or pharmacy to fulfill the order.
| Capability | What an outside app could do | How the transaction finished | Interface described |
|---|---|---|---|
| QuickPrint photo orders | Send digital images to Walgreens for printing | Customer picked up the printed order at a Walgreens store, generally the same day | First open API, launched July 2012 |
| Prescription refills | Scan a Walgreens prescription-bottle barcode and request a refill; eligible non-Walgreens prescriptions could be transferred to a nearby Walgreens | Walgreens pharmacy processed the refill or transfer and notified the customer for pickup | RESTful API announced February 4, 2013; usable from web servers or mobile platforms |
| Store information | Retrieve location data for app experiences | Usually a handoff to a selected Walgreens location | Later API expansion; Walgreens replaced a spreadsheet/CSV process with APIs |
| Offers and checkout-related functions | Varied by API and partner; the catalog has included digital-offer and photo-order functions | Depends on the individual API and whether Walgreens or the partner handled checkout | Availability changes; the developer portal displays a Digital Offers API deprecation alert |
The timeline
July 2012: QuickPrint
Walgreens’ first open API allowed photo applications to transmit digital images for printing at Walgreens stores. Instagram was cited as an example integration. The customer could start in the photo app and collect the physical prints from a Walgreens location.
February 4, 2013: Prescription API
Walgreens announced an API that used a compatible app’s scanning function to read a prescription-bottle barcode and order a refill. Walgreens described the service as RESTful, making it available to both mobile platforms and web servers.

2016: Broader API and checkout work
TechCrunch reported that Walgreens had added two APIs, converted store-location data from a spreadsheet/CSV workflow to APIs and moved Photo Prints checkout from an SDK to a RESTful API. That change matters because an SDK packages functionality for a particular development environment, while a REST API lets a wider range of clients communicate with a web service using standard HTTP requests and JSON-style data exchanges.
How a prescription refill through an outside app worked
- Start with a supported app. The app needed scanning capability and an approved connection to Walgreens’ prescription service.
- Scan the bottle barcode. The barcode identified a prescription originally filled at Walgreens.
- Submit the refill request. The app sent the request through Walgreens’ RESTful API rather than treating the scan as an independent refill system.
- Use Walgreens’ fulfillment process. For a non-Walgreens prescription, the documented workflow allowed a transfer to a nearby Walgreens. The pharmacy still had to process the request.
- Wait for pickup notification. The physical transaction ended when Walgreens notified the customer that the prescription was ready at the selected store.
Scanning a barcode did not guarantee immediate dispensing. Pharmacy review, prescription eligibility, transfer rules, inventory and store operations remained outside the partner app’s control.

Why Walgreens wanted outside developers
Walgreens reported 12 million visitors to Walgreens.com each week in 2013, and Walgreens figures reported by CIO said 36 percent of those visitors went directly to a local store. The company’s e-commerce CTO, Abhi Dhar, described mobile as a “perfect multichannel device”: a customer could begin an interaction digitally and finish it in a store.
That strategy gave Walgreens access to ideas and audiences it could not create entirely in-house. The company said it was already seeing incremental revenue from the open APIs, but Dhar identified a broader benefit: building “innovation capital” around a long-established brick-and-mortar brand and making Walgreens more attractive to technical talent.
The model also explains why the APIs emphasized practical handoffs. A photo order could be initiated in a social app, while printing, payment or pickup remained tied to Walgreens’ stores. A prescription request could begin with a scan, while pharmacist review and dispensing stayed with Walgreens.
How Walgreens built and governed the program
Shared interfaces and an API-management partner
Walgreens worked with Apigee to manage interactions with third-party developers and launch its developer portal. The company reused interfaces built for its own mobile products and adapted them for external use.
Rank #4
Developer-relations work
The technical interface was only one part of the program. Walgreens appointed developer evangelists, cultivated relationships, attended events and hosted hackathons to encourage useful integrations.
Operational and brand controls
External apps created risks that an internal app could manage more directly. Walgreens warned that store checkout had to remain stable, and every physical output—particularly printed photos—needed testing. Partner release cycles could move faster than Walgreens’ store and pharmacy operations.

Walgreens’ integration-marketing guide also required public partner materials that mentioned Walgreens to receive review and approval from Walgreens communications before publication. Developers therefore had to manage both technical approval and brand-communications approval.

Walgreens’ developer home page presents API documentation, API-key requests and an app gallery with integrations such as GoToPills and Culture Greetings. That shows the developer program and portal remain visible, but it does not establish that every historical endpoint is still available. The same portal carries a Digital Offers API deprecation alert, so availability must be checked for the specific API, account and use case.
- Review the current documentation for the exact endpoint you need.
- Check whether Walgreens is accepting API-key requests for that capability.
- Confirm authentication, geographic coverage, fulfillment limits and any approval requirements.
- Test store pickup, pharmacy responses and error handling before releasing an app.
- Recheck deprecation notices because Walgreens has changed interfaces over time.
A historical description of the 2012 or 2013 APIs should not be treated as a promise that an old integration will work unchanged.
What developers and consumers should expect
| Question | Practical answer |
|---|---|
| Does an outside app replace the Walgreens app? | No. It can provide a focused front end, but Walgreens still controls the connected retail or pharmacy service. |
| Is every step completed inside the partner app? | No. The defining pattern was digital initiation followed by Walgreens fulfillment, store pickup or pharmacy notification. |
| Can any app scan any prescription and refill it? | No. The documented workflow covered supported Walgreens prescriptions and permitted transfers, subject to pharmacy processing and eligibility. |
| Did Walgreens use only REST APIs? | No. Photo Prints was reported as moving from an SDK to a RESTful API in the later expansion; the program included more than one interface approach over time. |
| Can a developer earn money from photo orders? | The API catalog says developers can earn a revenue share for photo orders successfully placed and picked up at a Walgreens store. It does not publish a current commission rate, cookie duration or guaranteed enrollment path. |
What the initiative shows about multichannel retail
Walgreens’ approach treated an API as a bridge between a customer’s preferred digital tool and a physical operating network. The value was not simply exposing data. It was making a mobile action—printing a photo, requesting a refill or finding a store—lead to a reliable Walgreens outcome.

A partner could improve discovery or convenience, but it could not remove pharmacy rules, store capacity, pickup timing, API governance or Walgreens’ control over the final service. The program’s continuing relevance depends on those operational connections, not on the existence of a historical API announcement.
