Use this page before launch and whenever browser payment behavior looks inconsistent.

​
Test checklist

  • confirm the browser uses the sandbox public key
  • confirm the backend uses the sandbox secret token
  • verify the backend returns the transaction payload intact
  • verify webhook delivery before trusting browser state
  • reconcile any interrupted 3DS attempt

​
Example backend request

{
  "external_ref": "order_2001",
  "amount": 2490,
  "currency": "BRL",
  "method": "credit_card",
  "token": "pgct_token_from_browser"
}

​
Example backend response

{
  "success": true,
  "requestId": "req_4005",
  "data": {
    "id": "tr_2001",
    "status": "pending"
  }
}

​
Common error

{
  "type": "https://api.pagou.ai/problems/validation-error",
  "title": "Validation Error",
  "status": 422,
  "detail": "The request contains invalid data.",
  "errors": [
    {
      "field": "token",
      "message": "Token is required for credit card payments",
      "code": "invalid_type"
    }
  ]
}
Fix: if the backend cannot see a valid Payment Element token, stop and verify the browser integration before changing order logic or webhook handling.
