Zoho Billing data extractor

Import a new customer’s Zoho Billing data — addons, coupons, customers, and expenses, and 8 more object types — into your product as normalised, relational tables. Vern handles Zoho Billing’s auth, pagination and rate limits, so onboarding a customer off Zoho Billing doesn’t mean building and maintaining that plumbing yourself.

What Vern pulls from Zoho Billing

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 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 Zoho Billing'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 Zoho Billing 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 Zoho Billing'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

OAuth Client ID
OAuth Client Secret
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 Zoho Billing 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 Zoho Billing
ID=$(curl -sX POST $API/migrations -H "$KEY" -H "$JSON" \
  -d '{"name":"Acme onboarding","source":"Zoho Billing"}' \
  | 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.
