Yes, the subscr_id matches with PayPal ID

Something like:
S-5G6081345G6XXXXXX

I have several payments come in daily from automatic subscription payments and probably about once or twice a week a cancellation (eot) and new subscription happening. I don't think that would work if the subscr_id didn't match.

Would it be possible for an old CBSubs file, left over from a previous version, to be interfering?

Thanks

Thank you for looking into this.

I've looked into PayPal as you suggested and it seems the issue is that the cancellations need the 'Enhanced Recurring Payments' (ERP) Option for which PayPal is charging $20 a month now.

So my options are:
1- Pay the extra $20 monthly fee
2- Extend the grace period to 10 days (which seems excessive for a monthly subscription as it leads to abuses)
3- Continue to check for and reimburse double subscriptions.

Alternatively there is an option to ask PayPal not to retry failed payments in the initial subscription button. (According to this developer.paypal.com/docs/classic/paypal-payments-standard/integration-guide/html_example_subscribe/#reattempted-payments )
I've looked and I don't see it as an option in the CB Plan's settings.

Is this implemented in CB Subs? Of course it would only work for new subscriptions and not existing ones.

Thank you,
Tomás

I've contacted PayPal and they couldn't help me over the phone, they did direct me to create a ticket.
I'll update once I hear back.

Thank you,
Tomás

I've received an answer from PayPal:

Hi,

Can you please make sure that you have followed all the below process regarding Unsubscription.

1) PayPal have an API available to Unsubscribe the profile, were you just link directly to PayPals unsubscribe URL from Community Builder unsubscribe button if no API credentials are supplied. Can you please check this with the Community Builder developer.

2) The below API is used to cancel recurring subscriptions.

developer.paypal.com/docs/classic/api/merchant/ManageRecurringPaymentsProfileStatus_API_Operation_NVP/

3) Can you please confirm whether you have Option called "Enhanced Recurring Payments(ERP) " enabled to your PayPal Account as cancellations need this option for which PayPal will charge $20 a month.

Sincerely,

Am I the only one that has to pay the $20 to enable cancellations??
