KYC

Submit a verification questionnaire

Submit the customer’s answers to one questionnaire, named by type.

`type`	Answers	Applies to
`occupation`	`jobTitle`, `industry`	Every customer
`agreement`	`acceptTerms`, `signatureName`, `signatureDate`	Customers who accepted under your terms

Documents are uploaded through POST /organization/{organizationId}/verification/documents, including a region’s tax document.

agreement is a legal declaration, affirmed by acceptTerms: true. By default the customer accepts the agreement themselves in /idv. Send agreement only if your own terms incorporate ours and you already collected their acceptance. The customer agreement sets out what you are declaring.

Submit the customer’s personal data first, or this answers 409. As with document upload, the stage that asks these questions doesn’t exist on the customer until then.

Send agreement only once customerAgreement is in the requirements list. It belongs to the last stage, after the identity stage and any proof of address, so do not send it together with occupation. An early agreement answers 202, then is refused in the background, and a kycUpdated webhook arrives with needsWork: true. See Requirements unlock in stages.

Answers 202, not 200. industry is resolved against the live category list in the background, so an unrecognized value doesn’t fail the request: it leaves the occupation requirement outstanding.
