Zoho Expense Data Extractor

When a new customer signs up with their Zoho Expense account, Vern's Zoho Expense extractor pulls their full accounting history — customers, users, projects, and currencies — straight into your product through a single managed migration. You don't ask them to export spreadsheets or wire up Zoho Expense's auth flow yourself. It's built for teams onboarding users off Zoho Expense and getting their books into your app on day one.

Objects Vern extracts

Vern extracts the full set of queryable Zoho Expense objects (9 total), including: Currencies, Customers, Expense Categories, Expense Reports, Organizations, Projects, Taxes, Trips, and Users.

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 accounting system (e-conomic, Fastbill, FreeAgent) 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 Zoho Expense once during onboarding — their credentials never touch your code. Zoho Expense 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 Zoho Expense'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

Zoho Expense 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.

API quickstart

1. Create a migration for Zoho Expense
curl -X POST https://app.vern.so/api/v1/migrations \
  -H "x-api-key: $VERN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "name": "Zoho Expense → Postgres", "source": "Zoho Expense" }'
→ { "migration_id": "mig_..." }
2. Generate the extraction recipe (pulls live via the Zoho Expense API)
curl -X POST https://app.vern.so/api/v1/migrations/$MIGRATION_ID/runs \
  -H "x-api-key: $VERN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "kind": "generate", "extract_via_api": true }'
3. Run the approved extraction
curl -X POST https://app.vern.so/api/v1/migrations/$MIGRATION_ID/runs \
  -H "x-api-key: $VERN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "kind": "execute" }'
4. Download the normalized CSV export
curl https://app.vern.so/api/v1/migrations/$MIGRATION_ID/exports/{template} \
  -H "x-api-key: $VERN_API_KEY" -o zoho-expense_export.csv

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

Common questions

Can I keep a user's Zoho Expense data in sync after the first import? Vern supports re-running an import on demand; incremental change tracking depends on what Zoho Expense's API exposes for each object.

Can I move a user from Zoho Expense to e-conomic? Yes — Vern normalizes the Zoho Expense data model into typed tables that map cleanly onto e-conomic and into your own product.

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