API Url to update subscription

I want to update custom field for subscription via API, for my case field is quantity. I have tried patch to https://api.infusionsoft.com/crm/rest/v1/subscriptions. It seems it not exist. Can anyone help

Hi @Jorge_Lazaro_Diaz,

You will have to use the XML-RPC API, as the REST API has limitations.

The “Data Service” allows you to update the Records.

The “RecurringOrder” Table is what you want to use.

To update the Custom Field, you need to prefix the Name with an Underscore, eg: _ABC

Hope that helps.
