Verify Sub-Merchants

In some cases, we may not be able to validate the merchant details submitted through the API and will thus request documentation from the merchant. When this happens, the issue_type will be one of additional_documents_required or identity_verification. In response, follow this guide to tokenize documents uploaded by the merchant. Once tokenized, you'll send the document ID in a POST /legal_entities/{id}/verifications request, as described in the Document Upload guide.
