Hello,    "Released" parameter from GET Supplier Invoice Endpoint is not a "DateTime" filter, but a conditional one. Parameter documentation should be modified to provide clearer information. We've informed the relevant team for that. (/controller/api/v1/supplierInvoice - Get a range of Invoices ) https://integration.visma.net/API-index/) "Release" parameter could filter the dataset to only return the "Supplier Invoices" which are released. (Invoice Status: Open/Closed. Please see the following information for details.) GET:     https://integration.visma.net/API/controller/api/v1/supplierInvoice?released=1     ------------------------------------------------------------------------------------------------------------------------------------- ℹ️ Supplier Invoice Document Statuses ℹ️ The invoice can have one of the following statuses, which tells you its stage in processing: On hold: Generally, this status is used for an invoice that is a draft. This is the default status for new documents if the Hold documents on the entry check box are selected in the Supplier ledger preferences (AP101000) window. An invoice with the On hold status can be edited. Balanced: After editing is completed, you take the invoice off hold, thus changing its status to Balanced. If the Validate document totals on entry option is selected in the Supplier ledger preferences (AP101000) window, you can take the invoice off hold only if you type the document control total. Pre-released: The status indicates that the invoice has been pre-released and requires expense reclassification. (This status is used only if the Support for expense reclassification functionality is activated.) Open: This status means that the document has been released (and approved, if required). Closed: This status reflects that the document has released and been paid. ------------------------------------------------------------------------------------------------------------------------------------- ...
