PayPal Checkout INVALID_TRANSACTION_AMOUNT error encountered during checkout.

The transaction amount is invalid or exceeds the allowed limits.

Understanding PayPal Checkout

PayPal Checkout is a payment gateway solution that allows businesses to accept payments online. It provides a seamless and secure way for customers to pay using their PayPal accounts or credit cards. The tool is widely used for its ease of integration and robust security features.

Identifying the Symptom

When integrating PayPal Checkout, you might encounter the INVALID_TRANSACTION_AMOUNT error. This error typically appears during the checkout process, preventing the transaction from being completed.

Exploring the Issue

What is INVALID_TRANSACTION_AMOUNT?

The INVALID_TRANSACTION_AMOUNT error indicates that the transaction amount specified is either invalid or exceeds the permissible limits set by PayPal. This can occur due to incorrect formatting, currency issues, or exceeding transaction thresholds.

Common Causes

  • Incorrect currency format or unsupported currency.
  • Transaction amount exceeding the maximum allowed limit.
  • Negative or zero transaction amount specified.

Steps to Resolve the Issue

1. Validate the Transaction Amount

Ensure that the transaction amount is a positive number and formatted correctly according to the currency standards. For example, use two decimal places for USD (e.g., 10.00).

2. Check Currency Support

Verify that the currency you are using is supported by PayPal. You can find the list of supported currencies in the PayPal Currency Codes documentation.

3. Review Transaction Limits

Ensure that the transaction amount does not exceed the limits set by PayPal. You can check the PayPal Fees and Limits page for more information on transaction thresholds.

4. Update API Request

Double-check your API request to ensure that the transaction amount is correctly specified. Here is an example of a valid API request:

{
"intent": "CAPTURE",
"purchase_units": [
{
"amount": {
"currency_code": "USD",
"value": "10.00"
}
}
]
}
