All 4xx HTTP errors returned by the API use the format below:
{"field": "error message OR ERROR_CODE"}
In the case of errors where a field that's required by the endpoint is missing or has an invalid value, you will receive an error message.
In some cases, an error code is returned. Below are these codes and an explanation of what they mean:
| Error Code | Explanation |
|---|---|
| DUPLICATE_TRANSACTION_FOUND | The transactionId you provided is already associated with another payment intent. You can only create one intent per transaction. To create a new one, you need to cancel the existing intent. |
| BUYER_NOT_APPROVED | The buyerId is not approved by NetNow and therefore does not have a credit limit associated with their account. |
| BUYER_NOT_FOUND | The buyerId is not associated with any accounts at NetNow. |
| CREDIT_EXCEEDED | The request you made will result in the buyer exceeding their credit limit. |
| UNCHANGEABLE_INTENT | You attempted to change a payment intent that is final. Once an intent is in the status cancelled or confirmed it cannot be changed. |
| INCORRECT_TRANSACTION | Each payment intent is associated with only one transaction. The body of the request included an incorrect transaction ID for this intent. |
