Amazon Seller Partner data extractor

Import a new customer’s Amazon Seller Partner data — get afn inventory data, get afn inventory data by country, get amazon fulfilled shipments data general, and get brand analytics alternate purchase report, and 49 more object types — into your product as normalised, relational tables. Vern handles Amazon Seller Partner’s auth, pagination and rate limits, so onboarding a customer off Amazon Seller Partner doesn’t mean building and maintaining that plumbing yourself.

What Vern pulls from Amazon Seller Partner

Managed by Vern

The parts you'd otherwise build yourself

Authentication

Your customer authorises Vern once through the vendor’s consent screen. Vern stores the resulting tokens encrypted, refreshes them, and attaches them to every request — you never handle the raw credential.

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. You import a customer's complete data without ever managing a page token.

Rate limits

API sources rarely publish their real rate ceiling until you hit a 429 mid-import, and many silently cap page size. Vern queues and throttles requests to stay under the limit, so a partial pull never lands a customer in your product with missing data.

Output shape

Normalised JSON per object with referential keys preserved and timestamps in ISO 8601. Delivered as JSON or CSV, pushed to your API or webhook, or loaded straight into your application database.

Schema drift

If Amazon Seller Partner changes what it returns between migrations, the agent notices the difference against what it recorded last time and raises it, rather than importing a customer with a column quietly missing.

What it learns

Everything Vern works out about Amazon Seller Partner's quirks — field formats, enum values, ID and date patterns — is written down against the source and applied automatically to every customer you migrate off it afterwards.

What your customer provides

  • AWS Seller Partner Account Type
  • AWS Environment
  • LWA Client Id
  • LWA Client Secret
  • AWS Region

Collected once, stored encrypted in a vault, and attached to every request. Credentials are never written into the agent transcript.

API quickstart

Run a Amazon Seller Partner migration from your own product

Create the migration, let the agent extract and map, then pull the result out — without your customer ever seeing a Vern dashboard.

app.vern.so/api/v1
API=https://app.vern.so/api/v1
KEY="x-api-key: $VERN_API_KEY"
JSON="Content-Type: application/json"

# 1 — create a migration against Amazon Seller Partner
ID=$(curl -sX POST $API/migrations -H "$KEY" -H "$JSON" \
  -d '{"name":"Acme onboarding","source":"Amazon Seller Partner"}' \
  | jq -r .migration.id)

# 2 — hand over the customer's credentials for this run
curl -X POST $API/migrations/$ID/source-connection -H "$KEY" -H "$JSON" \
  -d '{"credentials": { ... }}'

# 3 — the agent extracts, maps and previews, stopping before it writes
curl -X POST $API/migrations/$ID/runs -H "$KEY" -H "$JSON" \
  -d '{"kind":"generate"}'

curl $API/migrations/$ID/preview -H "$KEY"

# 4 — approve, then pull the normalised rows back out
curl -X POST $API/migrations/$ID/runs -H "$KEY" -H "$JSON" \
  -d '{"kind":"execute"}'

curl -X POST $API/migrations/$ID/exports -H "$KEY" -H "$JSON" \
  -d '{"slugs":["customers","invoices"]}'

The Migration API runs the whole lifecycle over HTTP with an organisation-scoped key. The agent conversation can be streamed into your own UI, and the preview lets you check exactly what an import will produce before a single row is written.
