I'm trying to retrieve an invoice via the API with the endpoint /accounts/{accountId}/invoices/{invoiceId} but in the documentation it is impossible to make the call work:
https://app.swaggerhub.com/apis-docs/WildApricot/wild-apricot_public_api/8.03.0#/Finances.Invoices/GetInvoiceDetails

The first parameter which should correspond to accountId is replaced by () and in the return example there is only "string".
If I test the endpoint, the accountId parameter is not sent with my value.

For information, I tested other API endpoints and they work:
- /
- /accounts
- /accounts/{accountId}
- /accounts/{accountId}/contacts
- /accounts/{accountId}/contacts/{contactId}

So I tested a PHP example provided by Wildapricot:
https://github.com/WildApricot/ApiSamples/blob/master/PHP/sampleApplication.php
I replaced the connection values and everything works fine.

I tested the endpoint /accounts/{accountId}/invoices/{invoiceId}
and I have a 404 return code which means not found.

I made a call to the endpoint /accounts/{accountId}/invoices
and I have a return code 400 which means bad request.
I added the invoiceId parameter but still the same error.

Do you need to do anything special to use endpoint invoices?

Note that in the authorized app, I checked full access.
