Currently when creating an inovice there is no way to get the _id paramater of the tax that was created through the UI. The only way to get this id is to manually creating an invoice with that tax tied to it then doing a Get reqeust to get that invoice which then shows the _Id of the tax.
Hoping to get that endoint along with associated name, description etc so can be use as an RPC.
Also maybe the ability just to include the _id of the tax which then the system would know all the rest of the information it needs as it has all decription, taxId , rate etc.. already stored.
