CommentGate

CommentGate helps site owners turn comment access into a paid engagement flow. Visitors enter one email address, complete payment through Stripe or PayPal, and unlock the comment form for protected content.

Use CommentGate for paid communities, expert Q&A posts, premium discussion areas, gated announcements, niche publications, and any site where comment access should have value.

Main Features

• Pay Before Commenting – Hide the comment textarea and submit button until payment access is verified.

• Stripe and PayPal – Enable Stripe, PayPal, or both payment gateways.

• Per-Content Control – Enable paid comments globally, then override settings per post, page, or supported custom post type.

• Flexible Pricing – Set a global price, custom per-content prices, and currency from a dropdown.

• Default USD Currency – Start with USD, then switch to another supported currency when needed.

• Email-Based Access – Guests enter one email address for receipt and access tracking.

• Logged-In User Support – Logged-in users can unlock comments with account-based access.

• Auto Approve Paid Comments – Paid comments can be approved automatically after CommentGate access is verified.

• Admin Payment Email Alerts – Send the site administrator an email when a payment completes with site From and Reply-To headers.

• Customer Email Templates – Send payment-complete and refund emails through WordPress mail using HTML invoice format by default or simple text-style email, with an optional Media Library logo for HTML emails, editable templates, payment/refund previews, and footer.

• Secure Email Access Links – Let customers reopen the paid comment area from their receipt until comment credits are used or access expires.

• Role Exemptions – Let selected roles comment without payment.

• Optional Access Expiry – Limit how long a duration-based payment unlock remains active in minutes.

• Appearance Controls – Customize payment button text and optional custom button colors.

• WP-CLI Support – Inspect settings, list payments, view payment records, and refund unused paid access from the command line.

CommentGate Dashboard

CommentGate lives under Comments > CommentGate and includes one tabbed dashboard:

• General Settings – Enable CommentGate, select post types, choose currency, configure price, free roles, access type, access duration in minutes, comment quantity, and auto approval.

• Transaction History – View earning summaries, filter by paid/pending/refunded status, gateway, and date range, export CSV reports, refund unused paid access, and manage pending or deleted transactions.

• Payment API Configuration – Add Stripe or PayPal API credentials and webhook details, then review the setup checklist.

• Email Settings – Configure admin payment alerts, customer payment emails, refund emails, HTML invoice or simple text-style email format, optional Media Library logo or logo URL, editable email templates, payment/refund previews, and the email footer.

• Appearance – Customize button labels and optional colors.

General Settings also includes a quick link to WordPress Website Discussion Settings so comment moderation, notifications, avatars, and default discussion rules stay easy to reach.

Payment Gateways

CommentGate can enable one or both payment gateways:

• Stripe Checkout

• PayPal Checkout

If both gateways are enabled, visitors can choose Stripe or PayPal on the payment wall.

Third-Party Services

CommentGate connects to third-party payment services only when an administrator configures a gateway and a visitor starts checkout, returns from checkout, when an administrator starts a refund, or when the payment service sends a configured webhook.

Refunds

Administrators can refund paid transactions from Transaction History when access has not been used. For comment quantity access, unused means all purchased comment credits are still available. For duration access, unused means CommentGate has not attached the payment to a submitted comment.

Refund actions call the configured Stripe or PayPal API, then mark the payment as refunded in CommentGate with refund ID, reason, and refund date fields when available.

API Documentation

Use these official guides when creating payment credentials:

• Stripe API keys: https://docs.stripe.com/keys

• PayPal REST API credentials: https://developer.paypal.com/api/rest/

Webhook Events

For Stripe, configure the webhook URL shown in CommentGate and send these events:

• charge.refunded

• checkout.session.async_payment_failed

For PayPal, configure the webhook URL shown in CommentGate and send this event:

• PAYMENT.CAPTURE.REFUNDED

Copy the PayPal webhook ID into CommentGate settings so webhook signatures can be verified.
