A huge business opportunity awaits online retailers who take advantage of Amazon’s seller central and Amazon SP API (Amazon Selling Partner API) by connecting with the largest e-commerce platform in the world and its millions of users. The learning curve for this new platform can be steep, so we’ve put up a comprehensive post to help you get started.

Setup and security of your Seller Central Account, applicable seller fees, Amazon metrics, business analytics, advertising and promotional efforts, and typical mistakes will all be briefly covered in this article.

Amazon Seller Central 

Amazon Seller Central is a web-based, all-inclusive tool designed to help Amazon merchants organize, control, and improve their sales efforts. Sellers may manage their entire business from this centralized location, from listing creation and editing to inventory tracking and customer service. The highly touted Amazon SP API helps sellers to pull their products and other selling details from a centralized database.

Sponsored Products campaigns, a form of sponsored advertising popular on Amazon, allow vendors to reach customers who are actively researching products like theirs. Brands can increase sales by exposing their items to consumers through this function.

What Exactly is the Amazon Selling Partner API?

The SP-API, or Selling Partner API, is a set of REST APIs updated to conform to the needs of modern software architects. With the SP-API upgrade and Amazon’s offered tools, supporting the migration of current MWS integrations will be as easy as feasible, even though the MWS APIs will be deprecated in the future.

For Amazon’s selling partners, the Amazon Selling Partner API is the next generation of API-based automation features. The Selling Partner API has been released for use by both new and existing developers with the intention of further automating data flow and streamlining essential operations, analytics, and seller insights. 

Amazon Selling Partner API Tools

With the release of the Amazon Selling Partner API, both suppliers and sellers have access to a powerful set of data collection, analysis, and reporting tools. Retail Analytics and Amazon brand analytics are two cutting-edge tools that will help you streamline your business processes. Amazon’s revolutionary SP API will replace the deprecated MWS API in the future, streamlining sales processes for businesses of all sizes.

What are the New Features of the Amazon SP API?

The older Amazon MWS API (Amazon Marketplace Web Service API) has been retired in favor of the newer Amazon Selling Partner API. All new API features will be developed in the SP API beginning in September 2021, with Amazon MWS API updates made exclusively to support business-critical modifications. 

Steps to Take If You Want to Sell on Amazon

Since the switch to SP-API began in September, you should confirm with any third-party applications and suppliers that they plan to make the switch to Selling Partner API by September 2021. Similarly, if your Amazon business uses custom-built apps, your team should prepare for the transition from Amazon MWS to SP-API.

While most Amazon sellers won’t be directly affected by these API changes, business users and developers are encouraged to investigate SP-API capabilities, study Amazon’s SP-API documentation and your existing integrations, and/or prepare for a migration.

What Benefits Will I Get From the Amazon Selling Partner API

The new Selling Partner API provides the same direct, programmatic access to your data as MWS does. The information that drives your e-commerce operations is now in your hands.  The new Amazon Selling Partner API will help Amazon merchants in several ways, including gaining safe access to Amazon’s data silos, automating data, reducing manual processes, and gaining insights on when customers may be more inclined to buy, all of which can be used to better manage inventories.

Managing Orders, product pricing, sales, and more 

The SP-API (Selling Partner API) performs all of the same functions for orders, product pricing, sales, and more as the MWS-API (Marketing Web Service API). However, there are significant technical variations, both positive and negative, that you should be aware of. While working with the Selling Partner API for the first time, many people run into a few roadblocks.

Instructions for Basic Assembly 

The SP-API installation process is difficult and may be frustrating despite being well documented. The number of keys, tokens, accounts, and secrets you’ll need to refer to during authentication can be daunting, so it’s a good idea to keep a notepad or text editor open as you go. 

If you make a mistake when using the Amazon Selling Partner API, you won’t get very helpful feedback, making it difficult to figure out where you went wrong. On our first attempt, we substituted a “User ARN” for a “Role ARN” at a spot where we should have used the latter. We ran into some difficulties because the errors we received when making API calls were never specific enough to pinpoint the cause of the problem.

Final Thoughts

Businesses that still rely on time-consuming manual tasks like report downloads, file manipulation, and file processing might grow more quickly by using API automation.  After the year 2020, the MWS API would no longer accept new users and Amazon will instead direct them to the newer Amazon Selling Partner API. Amazon currently recommends that all users switch over to the SP-API, but has not announced a sunset date for the MWS-API. Developers working on Amazon integrations should be familiar with the new API and its advantages and disadvantages.
