Are you Amazon SP-API ready ?

Amazon Introduces Selling Partners Vendors API

Automating the exchange of data has been difficult with Amazon VendorCentral and is a considerable challenge for vendors. Intensive workaround methods had been followed for creating precise orders. It includes file import and export manually and other data scraping methods. EDI (Electronic Data Interchange) based software solutions are also standard, but outdated and controlled technology with lesser improvisations. Hence, they lack the efficiency that most vendors look for.

The simplest way so far to process orders is by using an API (Automated Protocol Interface). APIs permit almost instantaneous automatic communication among various software pieces. It lets the users to rapidly and effortlessly connect their existing order processing software to Amazon’s structure. However, many vendors never could use API available, regardless of sellers and affiliates, having access to Amazon APIs for years together.

All about Amazon Selling Partner API

Open Architecture to Encourage Integration
Amazon has currently deployed the next-generation version of the Amazon Marketplace Web Service (MWS) for its VendorCentral hub. It is known as the Selling Partner API (SP-API). The REST-based API version of the current MWS API is being used worldwide by the sellers. This new API will also include Vendor APIs along with the entire current MWS APIs. However, it does not affect or alter the existing MWS APIs. It has OAuth 2.0 for access delegation with Amazon.

The API connects with the system and programmatically access their data on listings, orders, reports, payments, etc. No additional actions are required for sellers who use Third-party applications for MWS APIs. It supports all the marketplaces.
Like MWS, the new API permits sellers to automate data access to increase selling efficiency and manual process automation. It also lets sellers explore insights on likely customers’ chances to make a purchase, let know inventory management decisions, optimize ad spending, target special offers, discounts, and promotions.

The present MWS APIs may be deprecated in the future; however, the date hasn’t been set yet. Prior intimation will be floated by Amazon to let all sellers know about deprecation and provide sufficient time and tools for migrating to the new version of API. Existing developers need to create SP-API applications to utilize the SP-API.

The Selling Partners API is organized into various sections that cover the following,

  • Inventory Management
  • Order Fulfillment
  • Payment Management
  • Transaction Management

The self-serve section of EDI is undergoing constant upgradations, and for now, it includes connecting options to with the below,

  • Global Settings
  • Purchase Orders
  • Advance Shipment Notifications
  • Invoices
  • Cost and Inventory feeds
  • Sales reports
  • Purchase order changes
  • Purchase order change acknowledgments

Significance of SP-API

Simplified data fetching
The SP-API is REST API with JSON response, whereas the old/current version is based on SDK and SOAP-based. To fetch information from protected XML, the developer has to call the specific function on response data. Since the new API is JSON based, it becomes easier for developers.

Enhanced security
The API is more secure as it is based on OAuth 2.0 with token expiry. The current API lacks such functionality, and by having the MWS details, one can access and perform almost anything. With OAuth 2.0 in the picture, the developer will need to refresh the token every time it expires, even though MWS details are in hand. So this new API is more secured compared to the existing one.

Major Benefits of Using an API for Retail Procurement

Transparent Purchase Management
With an API in place will drastically improve the efficiency and profitability of numerous Amazon vendors. The APIs offer several benefits for Sellers in retail procurement businesses, and they are as follows:
Low costs incurred – Utilizing an API reduces the need for manual data entry while handling purchase orders, leading to fewer labor costs overall.

Lesser process errors
Manual input processes may be extremely fallible, whereas an API processes orders depending on the exact information offered by Amazon. It helps to maintain order accuracy in terms of both product type and quantity.
Enhanced vendor performance – API offers quick feedback to improve the seller’s lead time, confirmation, and fill rates. It enables them to process more orders and potentially draw in more business.

On-time automated billing
APIs help submit accurate auto-generated invoices and make payments on time for every order processed.
Fewer chargebacks – Amazon’s chargeback fees are applied whenever a vendor fails to comply with the company’s guidelines regarding shipping and fulfillment. Automated systems like an API work on set rules and in real-time around the clock. So using API will remove the timing and accuracy issues that invite chargeback fees.

Great scalability
with the growth of the company, there arises the need for expansion. But in the case of API, it stays constant irrespective of business size, providing the needed scalable solution for sellers to expand their reach in Amazon Retail quickly.

Final Thoughts
While EDI did serve its purpose over the years, the addition of a new API for Amazon vendors reveals a new realm of potentials in the aspects of functionality, customization, and responsiveness. Since business on Amazon is dynamic, vendors’ chances are more to experience lower cost and flexibility that API can provide.
