Upload a document for a subaccount request.

Available to: Organization administrators

Environments: Production

Rate Limit: 10 requests per hour with 30-second back-off penalty

After creating a subaccount request, use this endpoint once per documentType to upload each of the three required documents.

<Warning>Warning: This endpoint returns HTTP 200 for successes and business errors. Always check the errorText field in the response body to determine whether the request succeeded or failed.</Warning>

subAccountRequestId

For subAccountRequestId, use the requestId returned from createpartnersubaccountrequest.

base64data Format

Documents are submitted inline as base64 data URIs. The base64data field must be a data URI with a supported MIME type prefix. The maximum field length is 8,388,608 characters (approximately 6 MB).

data:<mime-type>;base64,<base64-encoded-content>

Supported MIME types:

• application/pdf
• text/plain
• image/<file type> (for example, image/png or image/jpeg)

Size Limits

• Maximum request body: 5 MB
• Effective maximum file size: ~3.5 MB (base64 encoding adds ~33% overhead)
• Filename length: 5-64 characters

Re-upload Behavior

• Each document slot can only be filled once. The API rejects re-uploads to slots that already have a completed upload.
• If you uploaded the wrong document, contact Evaluation Support.

Common Failure Scenarios

• Invalid or non-existent subAccountRequestId
• Subaccount request is already Approved or Denied
• Invalid documentType value
• Missing or invalid data URI prefix in base64data
• Unsupported MIME type
• Document slot already has a completed upload
• Non-admin user attempting to call the endpoint
• Subaccount request belongs to a different organization
• POA contact not found on the subaccount request

Next Steps

After uploading all three documents, use the getpartnersubaccountrequeststatus endpoint to check the status of the subaccount request.
