API Bugs that Can Hamstring Your Value Chain

Running an API chain is no easy task, and there are plenty of obstacles to overcome. Check out the most common API bugs that can affect your performance.

Application Programming Interface (API) management is the key to better interoperability in the B2B network. It ensures supply chain integrity and scales businesses in ways that you have never seen before. The path to successful API management is riddled with challenges and they fail because of multiple reasons. Teams encounter many bugs and errors which hamstring the value chain. This is inherently an integration problem and it can be fixed with a little technical know-how.

APIs are important for businesses today. They assist organizations in implementing repositories that integrate production lines, manufacturers, third-party logistics providers in a standardized manner. We can explore APIs to authenticate contracts and gather data for the requests. APIs are important, but companies spend only a fraction of time in testing them. While testing APIs, It should be remembered that API bugs are inevitable and there are a number of factors that fail them. Many of the errors occur when companies deploy new technologies. Here are some prominent API bugs that IT teams should look out for.

200 is Not Ok

Developers check for 200 status code by pinging and validating an endpoint. The developers get a message that "The request has succeeded." But this doesn't mean that the API is perfectly ok. Many times, the API returns the request successfully, but issues still persist in them. Similarly, Facebook's Graph API returns a 200 status with errors tagged in the response data. Therefore, while validating an API, you should check the entire response in the header and payload. It is unwise to test API codes with manual testing methods.

Data Inconsistency Errors

Developers get fake results when they use a handful of calls against CSV data. Fake tests and fake data always deliver faulty results. Therefore, the codes should be tested with live data and databases. You should test the code with series of data and use it in subsequent calls. Tests deliver accurate results when real-time data is used for data prevent errors that disrupt partners from exchanging data.

Memory Leaks

In a literal sense, this is not an error but the inability of a code to release memory. It leads to increased memory consumption in applications and substandard system performance. Memory leaks are undesirable and should be eliminated with a robust memory leak detection strategy.

This API bug surfaces when an API program gets a lot of hits after becoming live. This error can be avoided with load testing. In the CI/CD process, the developers should hit those APIs to monitor machine memory. This practice ensures a good testing and deployment.

APIs that implement OAuth 2, require an Authorization  header for validating each request. Many developers often confuse the term authorization with authentication. The developers should confirm that they are using the right word for testing the APIs. More importantly, the OAuth 2 should be prepended with Bearer in this form: Authorization: Bearer your_api_token.  

You should monitor the value of syntax and it should have a right form:  Authorization: Basic base64_encode(username:password). Avoid mistakes like missing the Basic (note the space). prefix/ colon, or encoding the username and password or forgetting the colon.


Invalid Content Type

It is debilitating to see this API error which appears as <!DOCTYPE HTML>. It occurs when you forget to include an Accept header with your request. As a result the APIs fail to deliver data in the desired format. Some frameworks use HTML as the default format. Make sure to check for default errors if the APIs don't have to return HTML response.


The aforementioned were some common API errors that can restrain you from transacting smoothly with business partners. An automated B2B solution can help you climb these barriers and make the electronic data interchange (EDI) fast and smooth. A comprehensive solution uses a no-code approach to connect partner systems to help you create an engaged business community and drive business forward.
