API integration

Challenges of Working with APIs from Developers’ Perspective

Online services are highly interconnected with other systems. They prompt vendors to consume and expose data that fit in the ecosystem of related software. That is why vendors expose their application programming interface (APIs) and build integrations to exchange information with partner companies, customers, and internal software developers. Today, API integration is obligatory and APIs come with technological advances to reduce costs and boost productivity. Surprisingly, API integration is not so easy and it makes organizations face lots of challenges. Here, we will discuss some challenges that make things quite tough for developers when it comes to working with APIs. Moreover, these API integration challenges have always been software pain points for enterprises.

Developers and API Integration challenges

API integration is a set of API methods that connect different apps by sharing data. As far as the functionality of API integration is concerned, it allows performing CRUD (create, read, update, and delete) operations that consist of fundamental methods for managing and accessing data via RESTful APIs. The most common API integration difficulties or challenges vendors frequently encounter are high expensiveness; high time consumption; maintenance and upgrading; security risks; system diversity, and technological complexity. Moreover, in-house API integration also involves many challenges. Let’s move ahead and find how developers find working with APIs challenging.

Biggest challenge – API documentation

Developers face lots of hurdles but API documentation emerges as a surprising challenge sometimes. When documentation shows no real request/response information, developers have to call the API manually to prove the data. They find it hard to have credentials or reach a test or live system. In such cases, developers can’t test and verify the API integration functions appropriately.

Consistency vs inconsistency – Easy API vs Difficult API

Easy APIs come with a consistent data structure and structure of endpoints. Clear and concise documentation with an interactive format induces a big difference. OpenAPI standard with standardized formatting makes it easy for many developers to construe the API. Some difficult APIs are inconsistent like:

• Form post to submit data
• Response is JSON
• Just a string dependent on the endpoint called
• Data structure and field names not following a convention
• Documentation is very limited, not showing real headers
• Documentation not showing data requests, and responses or entity structures

Custom functionality creation not supporting API easily

Custom functionality is the basic need to mystify the UI complexity when there is any bespoke authentication. Developers normalize and manipulate user-friendly data in an integrated workflow to let 3rd party apps play well with other apps. Things become quite tough when standard data submission is not defined. It leaves the API in a bit of a messy structure. Filtering out records based on time range can also be challenging at some stages.

Common mistakes developers make while working with APIs

Evolving a design for internal purposes without thinking about how outsiders will view possible outcomes is a big mistake that developers can make while working with APIs. It is likely that design is developed by someone who has no idea of how apps work from an external user’s point of view. If developers don’t stick to the practice of external communication, they may fail to include defensive coding and tools to interact with APIs and prevent abuse.

Not identifying an ideal API

When we talk about an ideal API, it means sticking to standards and consistency. It helps you communicate information with more audience to your product and API. You better use patterns and standards that existed across the web. The ideal API should have the ability to filter the information of your choice when you deal with different workflows and repeated processes.

Wrapping up

When it comes to picking up particular tools while working with APIs, getting access to APIs using Postman or SOAP UI can help you interact, understand, play with the API. If you are looking for more on working with APIs, API integration teams at app development companies can help you. They can let you know more on do’s and don’ts of API documentation and authentication types.

API Integration can be a challenge for developers and enterprises as a software pain point. Sticking to the right practices can help you make the most out of your API integration efforts.
