Before submitting additional client data, the Platform needs to upload all supporting documents. Use File upload endpoint to upload documents. This endpoint is for file transfer and storage. We store the file until it is used/added in the application endpoint or until the specified file removal date. Currently API accepts one document per request, batch upload is not yet supported.
Based on security requirements, we check not only the document type but also the content type inside a document. For example, if the file extension is .jpg, but the actual content type is .exe, then such a document is not accepted.
Once you upload all required files, depending on client type (private or corporate), call endpoint POST Initiate personal application or POST Initiate business application.
