Example account limit errors

When an API request causes an account limit to be exceeded, you'll receive a 402 response code. The response body indicates which account limit was exceeded.

50-company limit

Error response from POST /companies when you have exceeded the 50-company limit that applies to the Free trial.

For example:

"statusCode": 402,
"service": "PublicApi",
"error": "CompanyValidationException: Company limit exceeded",
"correlationId": "00000000-0000-0000-0000-000000000000",
"validation": {
"errors": [
"itemId": "Company",
"message": "Company limit exceeded. Learn more at",
"validatorName": "CreateCompany"
"warnings": []

365 day free account limit

Error response when your account has expired and you make a request to any endpoint. This error is returned if your Free account is older than 365 days and has expired.

"statusCode": 402,
"service": "PublicApi",
"error": "Payment Required",
"correlationId": "00000000-0000-0000-0000-000000000000",
"validation": {
"errors": [
"message": "Account expired. Learn more at",
"warnings": []

Correlation IDs in error responses

The content of an error response includes a more detailed error message and a correlationId, which can be used to identify a particular response. Please include the correlationId in text format if you are contacting Codat support regarding an error.

"statusCode": 404,
"service": "QuickbooksOnline",
"error": "InvoicePdfNotFoundException: Invoice not found for company 360cb9b3-d9cf-4f66-b8db-8a3523fe3dc5 and invoice ID 12345",
"correlationId": "131f0225-5467-421a-b179-4531d6b4a942"

Status codes in asynchronous push responses

Status codes for push operations created in the Codat API might be different from the status codes returned in the responses from the service providers.

When a push operation is created in the API, some service providers may use a 202 Accepted code, which implies that the request has been accepted for processing, but the processing has not completed. However, the push API may return a 200 Success code for the push operation successfully created in the Codat API.
