Import contacts

Import canonical contacts from CSV with target roles, explicit field mapping, conflict strategy and optional dry_run.

Returns per-row classifications; large imports may return 202 when queued.

curl -X POST https://api.factuarea.com/v1/contacts/import \
  -F file=@contacts.csv \
  -F 'target_roles[]=customer' \
  -F 'target_roles[]=supplier' \
  -F conflict_strategy=reject \
  -F dry_run=true

Limits: the file accepts CSV, TXT, XLSX or XLS up to 10 MB; target_roles accepts at most three distinct roles.
Use the preview endpoint before importing.
A queued import returns 202.

Client-generated opaque key (up to 255 characters; UUID v7 recommended) that makes retries safe: the first response is cached and replayed for repeats without re-executing the mutation. Reusing a key with a different body returns 409 idempotency_key_reused. See the Idempotency guide. Required on this operation: repeating it delivers an effect that cannot be taken back (an email sent, a file generated, a third-party call, a charge), so a request without this header is rejected with 422 idempotency_key_required before any business logic runs.

Length1 <= length <= 255

Factuarea-Version?string

Pin the API version (YYYY-MM-DD, Stripe-style date versioning) for this request; omit to use the key's pinned version, or the latest if none. Unsupported version → 400 unsupported_api_version; malformed → 400 parameter_invalid_format. The effective version is echoed in the Factuarea-Version response header. See the Versioning guide.

Formatdate

X-Active-Profile?string

Operate on behalf of a child company (gestoría master key): pass its public id (UUID v7) and the request runs against that child's data without changing the key's scope, tier or environment (omit to use the key's own company). Invalid UUID → 400 parameter_invalid_uuid; unknown or non-owned id → 404 profile_not_found. See the Acting on behalf guide.
