Steps
The Greenhouse Ingestion API is a separate API from Harvest and uses a different base URL; obtain the Ingestion API key from your Greenhouse account under the partner or integration settings.
Authenticate with Basic Auth using the Ingestion API key; the base URL is https://ingestion.greenhouse.io/v1.
POST /v1/partners/candidates to create or update a candidate in Greenhouse from an external source; include the candidate's name, email, and source (your integration name) in the request body.
Map external profile fields to Greenhouse's supported fields; the Ingestion API accepts first_name, last_name, email_addresses, phone_numbers, website, social_media_addresses, and a custom remote_id for deduplication.
The response returns a Greenhouse candidate_id; store the mapping between your system's record ID and the Greenhouse candidate_id for future updates.
To update an existing candidate, include the remote_id field that you previously stored; Greenhouse uses it to match and update the existing record rather than creating a duplicate.
Known gotchas
The Ingestion API and Harvest API use different API keys and endpoints; do not attempt to use a Harvest key on the Ingestion API endpoint.
The remote_id field is the deduplication key — if you omit it on subsequent syncs, Greenhouse may create duplicate candidate records instead of updating the existing one.
The Ingestion API is intended for partner sourcing use; it does not support all the same fields as the Harvest candidates endpoint, and unsupported fields are silently ignored.
