What is API Access?
API allows developers to interact with the platform programmatically, enabling the integration of Seller Assistant's powerful features into your own applications and workflows.
Through the API, you can access a wealth of data and functionalities that are otherwise available through the Seller Assistant interface.
Jumpstart your integration with our ready-to-use API requests. We've created a collection of pre-configured requests that make it easy to access essential data and functionalities without extensive setup.

What API access is useful for?
User Info
Products
UPC-EAN-ASIN converters
The EAN-to-ASIN conversion feature performs a lookup to find an associated ASIN for a given EAN. This process relies on the existence of ASINs linked in Amazon's database and ensures accurate mapping of product identifiers, minimizing manual effort and potential errors.
Restrictions
Check ASIN restrictions by ASIN and domain – returns one of ALLOWED_TO_SELL, NOT_ELIGIBLE, or APPROVAL_REQUIRED
Sales Estimation
When a sales estimate is unavailable, estimated sales are null. A real estimate of 0 stays 0.
When Amazon does not return an FBA fee or a referral fee, that fee is null. fees.amazonFeesAvailable is false when either fee is missing.
Keepa
Get Keepa product, search Keepa products, and run the Keepa Product Finder. These endpoints have their own, stricter rate limit – see the Note below.

List and get your inbound plans, with their shipments, boxes, items, and fees.

Public API v1 inventory resources (products, suppliers, warehouses, purchase orders and their items, SKUs, listings, tags, notes, documents, and the repricer) share one response shape: data, meta.pagination, and errors for a batch. Lists use filter[field][op] and sort=-field. The cabinet API keeps its own responses.
Note
The limit is 60 requests per minute. Keepa endpoints are limited to 10 requests per minute. Amazon Seller Account must be connected to your Seller Assistant account.
Important
During the free trial you can use the API with up to 500 requests in total, or your plan's API allowance if it is lower. List endpoints return the first 25 rows on trial. Your full plan allowance starts when your subscription starts.
