Output schema

Normalized JSON per object with referential keys preserved, so the relationships between your user's records survive the import. Timestamps are returned in ISO 8601. Delivered as JSON or CSV, or loaded straight into your own application database or pushed to your API — whatever your product expects.

Where it can land

Your own application database (Postgres, MySQL), a direct push to your API or webhook, or JSON/CSV files, plus another e-commerce system (Adobe Commerce (Magento), Akeneo, Easypost) when a user is switching tools.

Source details

Built for the source type shown above, with extractor content refreshed from the collection record.

Managed by Vern

The details you normally have to build yourself.

Authentication

OAuth 2.0 (Authorization Code flow). Your new user authorizes Amazon Seller Partner once during onboarding — their credentials never touch your code. Amazon Seller Partner access tokens are short-lived and refresh tokens roll on the provider's own schedule, so Vern manages the full token lifecycle and refresh and the import never drops midway.

Pagination

Vern detects and handles Amazon Seller Partner's paging model (cursor, page-number, or offset) internally and returns one consistent, de-duplicated result set — so you import a user's complete data without ever managing page tokens.

Rate limits and gotchas

Amazon Seller Partner enforces its own API rate limits. Vern queues and throttles requests internally so importing a new user's data never trips a 429 — even on a large account.

OAuth-based sources expire access tokens frequently and require a working refresh flow — a dropped refresh is the most common cause of a half-finished import. Vern owns the refresh loop so a new user's onboarding completes even on a long extraction.

3. Run the approved extraction
curl -X POST https://app.vern.so/api/v1/migrations/$MIGRATION_ID/runs \
  -H "x-api-key: $VERN_API_KEY" \
  -H "Content-Type: application/json" \

A cleaner way to extract without rebuilding source-specific plumbing.

Common questions

Can I keep a user's Amazon Seller Partner data in sync after the first import? Yes — 45 Amazon Seller Partner objects support incremental change tracking, so after the first full import Vern pulls only what changed on re-run.

Can I move a user from Amazon Seller Partner to Adobe Commerce (Magento)? Yes — Vern normalizes the Amazon Seller Partner data model into typed tables that map cleanly onto Adobe Commerce (Magento) and into your own product.

What does it cost to read the Amazon Seller Partner API? Amazon Seller Partner's own API access follows Amazon Seller Partner's pricing/plan; Vern is billed separately per import. Check Amazon Seller Partner's developer docs for their current limits.
