Get accreditation detail

Account id — usable in all banking endpoints once status is ACTIVE.

unico = CorpX-managed facial biometrics (default); external = provider enabled by CorpX on request.

PJ only — corporate form from create.

PJ only — uploaded company PDFs.

PJ only — kinds required for this legalForm (operator approve gate).

PJ only — required kinds not yet uploaded.

Optional. Where to send the account holder back to when the step is finished (facial capture, terms acceptance or portability authorization). Without it the holder ends on a CorpX completion page, as before.

The URI must be registered for your tenant by CorpX support before the first use, and the match is exact — no wildcards, no prefix matching. An unregistered URI is rejected at creation time with 400 invalid_callback_uri.

Accepted: https:// and your application’s own scheme (deeplink). Rejected: http://, javascript:, data:, file:, credentials in the URI, fragments (#), localhost, private/link-local IP ranges and internal suffixes (.local, .internal).

On return, CorpX appends accreditationId, outcome, personId (for per-person steps) and remainingPeople (when the accreditation has more than one person). These parameters are not proof of anything: they travel in the address bar and the holder can edit them. Any decision with an effect must rely on the webhook or on GET /v1/accreditations/{accreditationId}.

Raw refusal from the banking provider, present only when a FAILED accreditation was refused by it. It is the same block delivered in the accreditation.failed webhook — the query never shows less than the webhook. All three keys are optional: the block mirrors what the provider sent, and some refusals carry message only. Informative — branch your code on errorReason, not on this.
