Updating customer properties - remember to regard updates as a consequence of changes in your customer dataset
We cannot emphasise enough on the fact, that the customer dataset is not the primary source in FarPay. When data are synchronized over your CRM link to FarPay, direct updates to this customers endpoint will be overrided from that source.
How ever - the attached payment option, will be reagred at the truth.
Update
The update is send as an PUT
https://api.farpay.io/v2/customers/123, where 123 is the referred customer number.
