Onboardings

Upload a shareholder document

Use this endpoint to upload the identity document for one onboarding shareholder. Send the file as multipart/form-data. The file must be a PDF, JPEG, or PNG and cannot exceed 20 MB. The expected document type depends on the shareholder type: an identification for a natural person, or the articles of incorporation for a legal entity. You can upload documents only while the onboarding is in progress.
