API Storefront vs Marketplace: Which is Right for You?

When planning to launch monetized API products, clients often consider opening up their developer portal to create a marketplace allowing the owner of the marketplace as well as third-party developers to publish APIs that can be consumed by the public (sometimes referred to as a multi-sided marketplace).

The most common B2C examples of multi-sided marketplaces are the Apple App Store or Google Play store. A B2B example was/is the Epic App Orchard (now Connection Hub) that allows third party developers to write applications and utilize APIs to interact with Epic’s Electronic Medical Record Software that is used by thousands of hospitals and contains data on ~80% of U.S. patients.

Creating a marketplace is initially attractive because it multiplies the potential for revenue generation and market participation. Apple’s model of capturing ~30% of all revenue that flows through its App Store certainly seems like an attractive business model to replicate, but the reality is that building this same experience is incredibly difficult and expensive, especially as a first step into the market of monetized APIs.

In fact, Epic’s experience with their app store serves as a cautionary tale for companies considering this path today. To summarize their experience, they first launched the store and were flooded with interested third parties who wanted to develop on the platform. Epic executives interviewed at the time likened the store to an Apple iTunes or Google Play experience for healthcare. ~2 years following the launch, they were forced to halt all enrollment to the platform over privacy and security concerns. After some delay and refactoring, they relaunched the marketplace with significantly revamped privacy policies, governance, and commercial terms.

If your company is considering launching an API marketplace, let’s explore some of the lessons learned from companies like Epic who have walked this path before.

Ensure that you can manage a traditional developer portal & API storefront before considering a multi-sided API marketplace

Successfully launching & managing a traditional API storefront & developer portal is challenging enough to get right, and ensuring you can maintain a healthy & active relationship with a group of interested third-party developers is a required first step. Launching your own developer portal will test your teams’ ability to write quality documentation, respond to developer questions, manage API version control and new releases smoothly, and maintain stability of the back-end systems supporting the APIs (among many others).

Secondly, adding an API storefront (commerce functionality for monetized API products) to your development portal will bring a new set of challenges.

Once you have built or procured mature systems & processes to manage the tasks above, the complexities will now multiply significantly as you move to a multi-sided marketplace. However, by first establishing the basic capabilities of an API commerce portal, you’ll be in a position to solve for them incrementally as opposed to all at once. The additional requirements for an API marketplace are discussed below.

Security & Privacy Concerns are Greatly Amplified When Reselling 3rd Party Applications & APIs

As the owner of an API marketplace, your responsibility is not only for your own code, but for the code & applications written by third-party developers. This will require you to extend your operational security practices & code reviews to teams who do not report to you. You also take on liability for the privacy practices of these developers, which creates a very heavy burden on your internal teams responsible for these areas. Based on Epic’s experience, you should not underestimate the costs of establishing the processes necessary to monitor third party security & privacy.

Payments Are Now Much More Complex

In a traditional API storefront, money moves between buyer and seller only. When you evolve into a multi-sided application marketplace, money moves between the app owner, the marketplace owner, and the app consumer, generally with a percentage of the transaction going to both marketplace and app owners. Establishing the amount you charge application developers to participate in the marketplace is a new challenge all its own, and something you should expect to have to defend over time (as Apple had to do during litigation with Epic Games) as your marketplace grows in popularity.

This new wrinkle in money flow may seem simple to accommodate at first, but the devil is in the details here as the application owners will rely on the marketplace owner to set up a payment management system as well. This will require you to allow third parties to configure varied & complex subscription models that run through your billing engine to collect money from the end user.

Finally, once that is accomplished, the marketplace owner will also be involved in the process of arbitrating refund requests from application consumers. This will require you to develop policies on refunds that extend across all marketplace participants and for you to staff the teams who will process these requests.

Legal Complexity & Liability Rises Significantly

Given the other sections covered above, this final point is likely no great surprise. Your company will be expected to promise a safe & positive experience for customers using the 3rd party applications in your marketplace based on the power of your brand. If and when something goes wrong with an application written by a 3rd party developer, the potential for legal exposure to the marketplace owner is significant, particularly if operating in regulated industries.

Because of this, the amount of legal support required from your team to initially launch the marketplace, approve individual applications, and re-certify them regularly over time will be considerable. While some smaller developers may be willing to accept click-through terms governing application resale on your marketplace, your larger customers likely will not, which will mean individual legal redlines for every new significant third-party service published in your marketplace.

So, Who Should Consider Launching an API Marketplace vs. an API Storefront?

There are a few key factors required to increase the chances of success for a new API marketplace / app store:

1. You operate an existing API storefront that is largely automated and supports developer self-service registration & payments. (for all the reasons described above)
2. You have significant brand presence - you should be a known leader in your space with strong brand preference from your pool of potential customers (i.e. Apple and Google for mobile app stores, Epic for EMR, Goldman Sachs for Investment Banking)
3. Your platform has broad developer appeal - the services you plan to make available via API have appeal across a diverse and often independent set of developers that you could not reach on your own with a traditional enterprise sales model (i.e. if your platform is only intended to be used by banks with more than $50 billion in market capitalization, it is unlikely that your platform can attract enough independent developers to justify the investment in a marketplace)
4. You can reach an extensive audience affordably - in addition to having a powerful brand, you need a platform with a large audience (i.e. Roblox, a popular online gaming platform is a leader in its space and creates profound developer interest due to their ability to create applications that will reach tens of millions of users every day)

Once you have number one above in place, and if your company profile matches the suggestions in points 2-4, the financial rewards from operating a multi-sided API/application marketplace can be significant, but as you can see, they do not come without a fairly significant investment in systems & processes to manage the associated complexities.  

As a result, for most companies, the multi-sided marketplace and app store is a great medium-term goal, but not the starting point.

If your current company profile doesn’t match the majority of the items above, we recommend a simpler first step into API commerce.
