List invoices

Returns a paginated list of all invoices of the company. The list contains invoice headers without positions — use the details endpoint to retrieve the full positions list.

Request

GET /api/oauth/v2/resource/invoices

Header

Header	Value
Authorization	Bearer {access_token}

Query parameters

Parameter	Type	Required	Description
offset	integer	No	Start position (default: 0, min: 0)
limit	integer	No	Number of results (default: 50, min: 1, max: 200)
createdSince	string (ISO 8601)	No	Only invoices created at or after this timestamp (createdAt >=)
createdUntil	string (ISO 8601)	No	Only invoices created at or before this timestamp (createdAt <=)
updatedSince	string (ISO 8601)	No	Only invoices modified at or after this timestamp (updatedAt >=). Newly created invoices are included, because the modification timestamp is set on creation.
updatedUntil	string (ISO 8601)	No	Only invoices modified at or before this timestamp (updatedAt <=)
status	string	No	Comma-separated list (default: all). Allowed values: active, deleted. Invalid value → 400 validation_error. See Conventions for details.
view	string	No	default (the default) or slim. slim returns only the most important fields per invoice — see Conventions for details. Invalid value → 400 validation_error.

Note: For a sync, updatedSince alone is enough — it covers new and modified invoices.

Note: Formats, time zones, sorting, cursor strategy, and the meta.total trap work the same across all filters. See Incremental Sync.

Note on deletions: Invoices carry no deletion timestamp of their own, but deleting one sets updatedAt. A deleted invoice stays visible via status=deleted (field data[].deleted = true), so it is detectable incrementally through updatedSince instead of disappearing from the list.

Response

Success (200 OK)
