Charges without a charge code - (ExistingChargeKey)

Hi,

The documentation states that a charge before 06/04/2013 won’t have a charge code so the ExistingChargeKey is needed to perform updates on the XML filing API.

Is there any field on the public API that displays the ExistingChargeKey and if so what field is it below?
https://developer-specs.company-information.service.gov.uk/companies-house-public-data-api/resources/chargelist?v=latest

Any help is appreciated.

I think you are referring to the charge number. In the spec it’s

“charge_number”: “integer”,

In the example
https://api.company-information.service.gov.uk/company/00002065/charges/12NQBAazndrpEQeeVJFjZ7m4rT0
it’s charge number 31, so that would be what you send in as the ExistingChargeKey
Hope that helps
