This page summarizes some of the errors and common issues that you may be encountered in runtime using the GeneXus SDK for Mercado Pago.

Create Payment

Invalid transaction_amount

Problem: When creating a Payment using PaymentCustomCheckout.CreatePayment, this message error is returned:

  "message": "Invalid transaction_amount",
  "error": "bad_request",
  "status": 400,
  "cause": [
      "code": 4037,
      "description": "Invalid transaction_amount",
      "data": null


  • The value for &PaymentSDT.transaction_amount is too small. For instance, paying with credit card returns that error for an amount less than $15.


Invalid User involved

   "message":"invalid parameters ",
         "description":"invalid users involved"

Cause/Solution: The buyer's e-mail address corresponds to a Test User and the seller credentials not.
