Due hosted submission (Endorsements/EDDs/RFIs)

Let users complete KYC/KYB submission requirements for endorsements, enhanced due diligence (EDD), requests for information (RFI), and similar workflows through Due’s hosted web interface.

Use this hosted submission path when a workflow creates a submission that requires additional data from the user—for example, after an endorsement request, EDD review, or RFI. Do not use this path for the standard KYC/KYB onboarding flow.

When to use this

Use this flow when an endorsement, EDD, RFI, or similar workflow creates a submission that requires additional data from the user. Create a session token for that submission and redirect your user to the hosted flow.

For standard KYC/KYB onboarding, use the regular KYC/KYB submission API flow instead of this hosted submission link.

Partial completion
You don't need to delegate the entire submission to the user. For example, you can programmatically submit available information via the API, leaving only the remaining requirements for the user to complete. When the user opens the hosted link, they will only see the remaining unfilled steps.

Create a session token

Use the submission.id returned by the workflow response as <SUBMISSION_ID>.

import requests

API_BASE = "https://api.due.network"
API_KEY = "YOUR_API_KEY"

response = requests.post(
    f"{API_BASE}/v1/kyc/sessions",
    headers={
        "Authorization": f"Bearer {API_KEY}",
        "Due-Account-Id": "<ACCOUNT_ID>",
        "Content-Type": "application/json"
    },
    json={
        "submissionId": "<SUBMISSION_ID>"
    }
)
response.raise_for_status()
token = response.json()["token"]

Response:

{
  "token": "eyJhbGciOiJFZERTQSIsInR5cCI6IkpXVCJ9..."
}

Build the submission link

Construct the URL using the submission ID and the session token, then present it to your user:

https://app.due.network/kyc_submissions/<SUBMISSION_ID>?token=<TOKEN>
