Plans - User approval upon payment verification

Hi, is it possible to set CB so that users paying plans with Paypal or similar are approved automatically, while those paying with bank transfer are approved manually upon payment verification?

There's no official feature for that. Approval can only be overridden per-plan. Best I can think of is to auto-approve them once their payment has completed using CB Auto Actions. Example as follows.

Global
Triggers: onCPayAfterPaymentStatusUpdateEvent
User: Automatic
Type: Code
Access: Everybody
Conditions
Condition 1
Field: Custom > Value
Custom Value: [approved]
Operator: Not Equal To
Value: 1
Condition 2
Field: Custom > Value
Custom Value: [var4]
Operator: Equal To
Value: Completed
Condition 3
Field: Custom > Value
Custom Value: [var2_gateway_account]
Operator: Equal To
Value: PAYMENT_GATEWAY_ID_HERE
Action
Method: PHP
Code:
This acts on the payment status change event for a basket. First it makes sure the user is already unapproved as there's not much point approving an already approved user. Then when a basket payment is marked completed (paid) it'll also check what payment gateway was used to make the payment. That is where we check against PAYMENT_GATEWAY_ID_HERE which should be set to the id of your PayPal payment gateway. Next it runs the necessary PHP to force the user approved.
