Hi,

I have start implementing business central API, I have successfully implemented '/salesInvoices' and '/salesInvoiceLines' data upload.

However, I have faced issue with attaching document to SalesInvoice in the endpoint '/attachments'.

Whatever document I upload, I am getting the error "The record in table Unlinked Attachment already exists.

I used following request

https://api.businesscentral.dynamics.com/v2.0/<tenantID>/uat/api/v1.0/companies(companyID)/attachments

Body:

{ “parentId”: “5a086bc7-195f-eb11-89f9-0022481ab2d5”, “fileName”: “Example.pdf”}

It was advised to retrieve the parent Id from the first successful attachment creation and use that parent Id in the PATCH request instead of creating a new one.

How to do that ? Which request I can use to retrieve the parent Id from the first successful attachment creation ?

Thanks in advance
