Errors
We have standardized how we handle errors across all of our APIs.
When an error occurs, we will return information about why the error occurred as well as the corresponding HTTP error code.

Validation errors (400 - Bad Request)

A Validation error will occur if you send a request that is missing a parameter or has a parameter with an invalid/unacceptable value. In this situation, we will return the HTTP status code 400 (Bad Request) along with error details.
So, for example, if you tried to call our IBAN validation endpoint without specifying an IBAN value, you would get the following response:
GET /iban/validate
RESPONSE:
{
"message": "'query.iban' is required",
"field": "query.iban"
}

Response structure

Whenever a validation error occurs your response will have the structure explained in the table below:
Key

Type
message

Not Found Errors (404 - Not Found)

If you send a request to a non-existent endpoint, you will receive HTTP status code 404 (Not Found), and the following JSON response:
GET /non-existent-endpoint
RESPONSE:
{
"message": "No endpoint matching requested URL was found."
}
