}

Another issue is that after creating products, plans and subscriptions through the API, these created products, plans and subscriptions are not visible in the dashboard (sandbox Paypal account). But when retrieving via api I get all the details. Please tell me why this is happening or where I can see this.

ps: I'm using the https://srmklive.github.io/laravel-paypal/docs.html api to create products/plans/subscriptions.

Answer 1

PayPal subscriptions are automatically billed based on the plan_id and/or billing_cycles of the overriding plan object when the subscription is created. That's what subscriptions are for.

When automatic payments are not missed, there are no outstanding balances to settle. Payments cannot be captured manually when there is no outstanding balance to be billed.
