Accept PayPal send-money. Add invoice # as note; payment is verified automatically from your receipt email. Annual license $100/year.
Product Description
PayPal IMAP Payment Gateway lets you accept PayPal send-money payments in WHMCS. Customers send the amount to your PayPal and put the invoice # in the note. The gateway connects to your email via IMAP, reads PayPal receipt emails, matches amount and note to the invoice, and marks the invoice as paid automatically. Licensed annually at $100/year per domain.
How It Works
You set the email that receives PayPal receipts and your IMAP settings. You configure a signing secret for secure, time-limited payment links. On the invoice, the client sees "Pay with PayPal" and is sent to a payment page with amount and reminder to add invoice # as note. After payment, the gateway checks your inbox, matches note and amount to the invoice, and marks it paid in WHMCS.

Frequently Asked Questions
What is PayPal IMAP?
It's a WHMCS gateway that accepts PayPal send-money payments. The customer sends the amount to your PayPal and puts the invoice number in the note. The module reads your PayPal receipt emails via IMAP and automatically marks the matching invoice as paid.
How does IMAP verification work?
You enter the email that receives PayPal receipt emails and its IMAP password (e.g. Gmail App Password). The gateway logs in, searches for PayPal receipt emails, and matches amount and note (invoice #) to the invoice, then adds the payment in WHMCS.
What if I use Gmail with 2FA?
Use a Gmail App Password for the gateway, not your normal password. IMAP host: imap.gmail.com, port 993.
Is the payment link secure?
Yes. The link to the payment page is signed with a secret and has an expiry time (e.g. 60 minutes). You set the "Signing Secret" in the gateway configuration.
Is this a one-time or yearly license?
Yearly. The license is $100 per year per domain. You need an active license for the gateway to work.
Which WHMCS versions are supported?
WHMCS 8.x and 9.x. The module uses standard WHMCS gateway and invoice APIs. PHP IMAP extension is required.
