Hi Drivewitherik, no code for auto approve subscriptions on Sandbox (unless somebody created something that works and can help this scenario) but what you could do is a manual approval of few sandbox subscriptions using sandbox buyer accounts. Once the subscription is created just call the approve link returned in the API response:
"href": "https://www.paypal.com/webapps/billing/subscriptions?ba_token=BA-2M539689T3856352J", "rel": "approve",
Then you can activate it.
