eboekhouden

eboekhouden_create_invoice

The tool first reads the relation, then sends its current values with your changes on top (the API requires name on every update), so fields you do not pass keep their values. This overwrites the current values of the fields you pass. GET + PATCH /v1/relation/{id}.
