Didn't getting Products/ Plans / Subscription that created by API with same account

[Kishan_Choudhar]

I created some products with plans and subscribe to them by using API but I didn't get them on UI in my account. 

Please help where I can find that plans, products, and subscriptions.

I am using the below URL with basic / bearer token authentication.

My Account activities look like this.

I didn't get that subscription on UI after activation.

Also, I am unable to refund payment for the subscription.

Can anyone please, How I refund the subscription last payment using API?

Thanks in Advanced.
