Questions about using Export Data API for payment status and invoice

Hi Candis team,

I’ve been looking into the API for reconciling payments, and I noticed that the data from the /invoices endpoint doesn’t fully match what we see in the UI. The documentation mentions that the API is primarily read-only but includes “a limited update capability for maintaining payment status metadata.”

I also checked the Export Data endpoint (Create an Export https://developer.candis.io/reference/create-export), but I don’t see a way to specify a date or filter when creating an export via POST. In my tests, this resulted in only a single record being returned.

Our use case is basically to account for all invoices across all organizations. Currently, we have a daily process that reads from the /invoices endpoint, but the data doesn’t fully match the UI.

Could you clarify:

How should we use the Export Data endpoint to get a complete set of invoice/payment data?
Is the API intended to support full invoice reconciliation across multiple organizations, or are there limitations we should be aware of?

Thanks in advance for your guidance!

Best regards,
Javier
