- Required fields are missing or contain incorrect values. - Field values do not match expected data types. - Currency codes are invalid or the amount formatting is incorrect. - The request body is not properly formatted as JSON. - The transaction is blocked based on the account’s status or configuration. - An incorrect or outdated API version is used. Some validation rules may change between versions.	The payment process stops, and the payer cannot complete the purchase. This can result in lost sales if not fixed quickly.	- Check the error details in the API response to find the exact field and issue. - Ensure all required fields are there and contain valid data in the correct format and type. - Update the request with correct data and resend it to allow the payment to process.
