Calendly Data Extractor

Vern's Calendly extractor imports a new user's productivity data — api user, event invitees, event types, and groups — into your product through a single managed migration, handling Calendly's auth, pagination, and rate limits for you. It's built for teams onboarding customers off Calendly who want their data in your app from day one.

Objects Vern extracts

Vern extracts the full set of queryable Calendly objects (6 total), including: API User, Event Invitees, Event Types, Groups, Organization Memberships, and Scheduled Events. 3 of these support incremental change tracking, so syncs pull only what changed.

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 productivity system (Acuity Scheduling, Airtable, BoldSign) 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

API key / access token. Your user pastes their Calendly API key once when they sign up; Vern stores it encrypted and attaches it to every request, handling header signing and retries so you never touch the raw credential. See Calendly's authentication guide.

Pagination

Vern detects and handles Calendly'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

Calendly enforces its own API rate limits (see Calendly's rate-limit docs). Vern queues and throttles requests internally so importing a new user's data never trips a 429 — even on a large account.

API-key sources rarely surface their true rate ceilings until you hit a 429 mid-import, and many silently cap page size. Vern throttles to stay under the limit and normalizes paging so a partial pull never lands a user in your product with missing data.

API quickstart

1. Create a migration for Calendly
curl -X POST https://app.vern.so/api/v1/migrations \
  -H "x-api-key: $VERN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "name": "Calendly → Postgres", "source": "Calendly" }'
→ { "migration_id": "mig_..." }
2. Generate the extraction recipe (pulls live via the Calendly API)
curl -X POST https://app.vern.so/api/v1/migrations/$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 calendly_export.csv

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

Common questions

Can I keep a user's Calendly data in sync after the first import? Yes — 3 Calendly 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 Calendly to Acuity Scheduling? Yes — Vern normalizes the Calendly data model into typed tables that map cleanly onto Acuity Scheduling and into your own product.

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