Nutshell data extractor

Import a new customer’s Nutshell data — account types, accounts, accounts list items, and activities, and 22 more object types — into your product as normalised, relational tables. Vern handles Nutshell’s auth, pagination and rate limits, so onboarding a customer off Nutshell doesn’t mean building and maintaining that plumbing yourself.

What Vern pulls from Nutshell

Know exactly what comes across before you migrate. Every object below is normalised into typed tables with referential keys preserved, so the relationships between a customer's records survive the import.

Managed by Vern

The parts you'd otherwise build yourself

Authentication

Your customer provides their sign-in details once. Vern stores them encrypted in a vault, never in the agent transcript, and uses them only for this migration.

Pagination

Vern detects and handles Nutshell'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 Nutshell 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 Nutshell'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

Username

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

API quickstart

Run a Nutshell 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 Nutshell
ID=$(curl -sX POST $API/migrations -H "$KEY" -H "$JSON" \
  -d '{"name":"Acme onboarding","source":"Nutshell"}' \
  | 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.
