The Most Common Problems with Amazon SP-API Integration

Are you an e-commerce entrepreneur looking to scale your Amazon business? If so, you may be considering integrating with Amazon's new Selling Partner API (SP-API) to take advantage of its advanced features and automation capabilities. You're not alone. According to a recent survey, 72% of businesses that use Amazon's Marketplace Web Service (MWS) are planning to migrate to SP-API in the next year.

However, integrating with SP-API can be a complex process, especially if you or your team members lack experience with this new platform. Let’s take a look at some of the most common problems that can arise when integrating with Amazon's SP-API, along with tips on how to avoid them.

4 Often Faced Problems:

1. Incorrect authentication: 

SP-API requires sellers to use a new authentication method that is different from Amazon Marketplace Web Service (MWS). If developers or team members are unfamiliar with this new authentication method, they may make mistakes when trying to authenticate with Amazon's servers, resulting in failed requests. To avoid this problem, make sure your team members are trained on the new authentication process and have access to updated documentation. SP-API uses OAuth 2.0 to authorize developer applications. The developer application is registered on Amazon Seller Central, and an authorization grant is provided to access the Selling Partner API. 

2. Improper data formatting: 

SP-API requires specific data formats for requests and responses. If developers or team members are unfamiliar with these formats, they may send requests with incorrect data or parse responses incorrectly, resulting in errors or failed requests. To avoid this problem, make sure your team members have a thorough understanding of the data formatting requirements and are using the correct tools and libraries to generate and process data. SP-API supports JSON payloads and uses a standard schema for most APIs. Amazon has provided several code examples and SDKs in various programming languages to help developers get started. 

3. Incomplete implementation: 

SP-API offers a wide range of functionality, and developers or team members may not be aware of all the available features. As a result, they may overlook important functionality or fail to implement certain features correctly, which can lead to issues with their integration. To avoid this problem, make sure your team members have access to comprehensive documentation and training on SP-API's capabilities. Amazon has provided detailed documentation for each API and code examples to get started with. 

4. Inadequate error handling: 

SP-API may return error messages with specific error codes and descriptions. If developers or team members do not handle these errors correctly, they may not be able to diagnose and fix issues with their integration, leading to further mistakes or issues with their Amazon business. To avoid this problem, make sure your team members are trained on how to handle error messages and have access to tools that can help diagnose and fix issues. SP-API provides detailed error responses with a unique error code and message. Amazon also provides an error response validator to help you identify and troubleshoot issues. 

Migrating MWS → SP-API

If you're migrating from MWS to SP-API, you may also encounter additional challenges related to the differences between the two platforms. For example, SP-API offers a new Orders API that replaces several MWS APIs, and some existing MWS functionality may not be available in SP-API. To ensure a smooth migration, make sure your team members are familiar with the differences between MWS and SP-API and have a clear plan for migrating your existing functionality to the new platform. Amazon provides a migration guide for sellers and developers to help with the transition. 

Why do you need it?

To learn more about the benefits of Amazon automation and why Amazon SP-API is better than MWS, check out our articles. But now, take a look at this statistic:

According to a study by Feedvisor, Amazon sellers who use API integrations experience 34% higher sales than those who don't. 

A survey by BigCommerce found that 48% of online shoppers said that they expect a website to load in two seconds or less, and 40% will abandon a website that takes more than three seconds to load. This highlights the importance of optimizing your e-commerce processes, including API integrations, to provide a seamless shopping experience for your customers.
