Clover 3DS Method Flow - Manual Testing

Step 1: Load Charge Response

Paste your charge response JSON from the POST /v1/charges call:

Loaded 3DS Data

Charge ID: Validation Result: Method URL: Server Transaction ID:

Step 2: Execute Fingerprinting

Click to start the 3DS fingerprinting process:

Fingerprinting Frame:

Debug Information

Waiting for 3DS process...

Step 3: Finalize Payment

The fingerprinting completed with status:

Now you need to call the finalize endpoint from Postman:

Endpoint:
POST https://scl.clover.com/v1/charges/finalize_payment

Headers:

Authorization: Bearer YOUR_API_KEY

            Content-Type: application/json

Request Body:

Step 4: Check Charge Status

After calling finalize_payment, check the charge status:

GET https://scl.clover.com/v1/charges/YOUR_CHARGE_ID

Status Check Result:

Look for updated threeds.validation_result:

CHALLENGE_FLOW_REQUIRED - Challenge needed
AUTHENTICATION_SUCCESSFUL - Frictionless flow
AUTHENTICATION_FAILED - Failed

Note about the CSP error:
The "frame-ancestors" error in the console is expected and doesn't prevent the 3DS flow from working. It just means the notification response can't be displayed in the iframe. The fingerprinting still completes successfully!
