Hi,

I got a warning from Paypal that IPNs sent to https://calendly-billing.chargebee.com/payment_gateways/paypal_ipn?id=xxxxxx (ID xxed out for security reasons) are not being processed. I should ask the service provider. What does this mean? Can you help?

Thanks,
Pisamai

Hi ​@Pisamai33450 - Thanks for reaching out!

I would start by reaching out to Paypal to see if they can add more context into whats going on. I’m not seeing anything widespread on my end, so Paypal is a good first step.

They may refer you back to our support team, in that case, you can either email support@calendly.com or use our chat help to get in contact with them!
