Developing an API is part of the software development process. To develop an API, the dynamics, architecture, and resources of the project should be considered. As the first step of API development, it is very important to determine the development definition and scope. Thus, developers clearly state what they expect from the API development process. As the last step, developers deploy and monitor the API they developed to a server. There are many paths to follow in API development processes.

An example of a path frequently followed in API development processes is as follows:

  • Understanding Need and Purpose
  • Choosing the API Architecture
  • Designing API Endpoints
  • Choosing the Right Technologies
  • Creating API Documentation
  • Testing the API
  • Adding Security Methods
  • Deploying and Monitoring

What Are the Steps to Sell Your API in API Marketplaces?

You can use many API marketplaces today to sell your own API. API marketplaces are platforms where developers list and sell their APIs. In this section, we will list the steps that developers can follow to sell their APIs.

API Marketplace Research and Evaluation

Firstly, developers search and compare API marketplaces online to list the APIs they want to sell. It is important to evaluate the target audience, user base, popularity, and marketing strategies of this marketplace when choosing an API marketplace.

Account Creation

Developers register and create an account with their chosen API marketplace.

API Listing Preparation

Upon completing the registration process on the API marketplace, developers then move on to the subsequent step, which involves preparing to list their APIs. During this stage, developers prepare detailed explanations and potential use cases to introduce the API to users.

Adding API Documentation

Developers prepare robust and detailed documentation before releasing the API to the API marketplace of their choice. This documentation covers many technical topics such as code snippets, integration code examples of different programming languages, API error codes, and API uptime information about using the API.

Pricing and Publishing

In the last step, the developers determine the subscription plans of their APIs. After setting broad subscription plans that will appeal to multiple budgets, they publish their APIs.

Although developing and selling APIs for developers seems very profitable and advantageous, there are some difficulties. This section covers some common challenges and how the APILayer API marketplace can help overcome them.

Discoverability: There are many APIs in the API marketplaces where developers list their APIs, and it is pretty challenging to highlight their APIs among them. APILayer has a structure highlighting the APIs it lists in this topic, and that many developers can easily examine the APIs. Additionally, there are many SEO-based blog posts about APIs listed under APILayer. Thus, APIs listed in APILayer can meet large audiences.

Integration Complexity: Integrating a new API added to an API marketplace into different systems can be difficult initially. As a result, this prevents developers from using new APIs. However, APILayer provides a service with highly innovative and advanced standards to API providers and API buyers in this regard. Especially each API listed on APILayer has integration codes for Java, PHP, Python, Go, and more programming languages. Furthermore, it also offers a ‘Live Demo’ service to developers. Thus, developers can quickly run tests on the platform before purchasing the API.

Issue of Trust: The trust relationship between API marketplaces and API buyers is very important. Otherwise, the value of the APIs added to the API marketplace will never be understood and discovered. APILayer verifies all APIs listed under it and ensures they meet specific quality standards. So, API buyers don’t have any doubts when they want to get an API from APILayer.


At the end of the day, in order to sell an API, developers consider many issues such as developing an API, monitoring the steps to sell an API, and tackling its challenges. But choosing the right API marketplace directly helps developers quickly sell their APIs and overcome almost any challenge in the API sell-through process.
