What is a Third-party API?

According to the name, a third-party API means a special program that connects functionalities from different apps. It is provided by a third-party, usually (but not necessarily) large enterprises, to enable you to access their data or software functionalities on your website or application.

An example of this is when a ride-hailing app, such as Uber, integrates a Map functionality from an app like Google Maps to track rides. By implementing a third-party API, Uber saves time on building map functionality from scratch.

How Does a 3rd Party API Work?

To understand how a 3rd party API works, we must first differentiate it from a first-party API. The latter is designed for internal purposes, while the former is an interface that allows you to connect your app to services from other companies.

An API is a reusable communication interface/medium between two apps; it creates shared functionalities and enables seamless, regulated data sharing. In the third-party case, the owner develops an app functionality as an API so that other apps can plug into their app features. To achieve this, integration code is made public as well as documentation concerning its implementation.

Key Benefits of Using a Third-party API


Before now, every new app maker had to build all its functionalities from scratch. However, now, software developers can take advantage of third-party APIs to access functionalities that would have otherwise taken time and effort to build. Therefore, a 3rd party API integration helps to save cost, time, and effort.

Avoid Data-Duplication

Google Sign-in enables several apps to use OAuth authorization credentials to manage user profiles. Without such an authorization API for third-party integration, every user has to create a new profile for every sign-up. More so, every company has to manage multiple data from the same sources.

Less Maintenance

A third-party API is easier to maintain. After all, it is owned, managed, and maintained by the company that develops it. For the third party, it is an easy ‘plug and play’ method. If you use third-party APIs from a reliable company, then you shouldn’t have any problems since maintenance and updates would always take place seamlessly. What is a 3rd Party API Integration?

What is third party api integration?

It simply means connecting an API from a third-party provider to your own app. It is continually maintained by the provider and the connection is enabled by means of special developer keys for the purpose. The process requires the expertise of a skilled mobile developer (for third-party API integration in Android or iOS) or a specialist API integration developer.

Why You May Need a 3rd Party API Integration?

For many startups that don’t yet have the resources to build their own complex functionalities, it can come in handy. APIs from established and reliable companies can open up your business to a whole world of possibilities that would have otherwise been inaccessible for your business.

For instance, building a map functionality for an app requires a lot of complex background work, not to mention the highly complicated process of building the app itself. In that instance, a startup is better off using an established third-party API in order to access rich data.

Let’s Check which Developer Fits You!

How to Choose the Right 3rd Party API for Your Project?


Every software product is usually accompanied by some form of documentation for developers implementing the product in their respective codes. Before choosing a third-party API, ensure that it has detailed documentation with clear information.


Developers turn to APIs for the sake of efficiency. Surely, you don’t want to use two different APIs when one can perform all the functions you need. A good third-party API would have robust but specific features that help you to reach your goal masterfully.

A third-party API is maintained by the provider, not you, the client. Therefore, you have to use tools with excellent provider support. How responsive is the provider? How frequent are the updates? What’s the maintenance schedule like? These questions require answers.


This is information gotten from other users who have tried the API. One that is frequently buggy on other platforms would probably not work well on yours too. Keep in mind that unexpected errors have real impacts on service delivery to your customers.


When you use APIs from a third party, you are inevitably sharing data with that provider. Hence, if the provider does not have high-level security and data encryption enabled, your data is probably not safe using that product.

How to Integrate Third-party API?

Hire an API integration developer

Integrating 3rd party APIs can get very tricky quickly for non-developers. Therefore, the best option is to hire a mobile developer or a developer that specializes in such. Of course, if you have none of these on your team, the best option is to use staff augmentation like software development companies such as ProCoders provide.

Consult the documentation

This is the obligatory first step for integrating third-party APIs into your project. The general procedures for integrating an API might be similar to each other, but there are specific concerns pertaining to each one.

Get the Developer Key

APIs usually require a special developer key (basically, an authorization token) to process connections and secure communication. Again, the exact details of how to access the developer key are usually contained in the documentation.


This is the integration proper stage when you connect it to your app. This is what establishes secure and regular communications between it and your app. Ensure that you adhere to the standards for security as you do so. What’s most important is that it functions well and properly with your app. That’s how to integrate third-party API.

Does a 3rd Party API Affect the Final Cost of Your Project?

One of the main benefits is that they help you to optimize resources and time as you boost efficiency. This in turn translates to significant cost savings. Therefore, a functionality that could have taken months to build can otherwise take only a few hours when you choose to integrate an API into your app instead.

This means less money expended on resources (infrastructure) and developers (working fewer hours). Therefore, how does it affect the final cost of your project? It ultimately lowers the cost so that your app can be well optimized.
