I’m looking for an experienced WordPress/PHP developer to build a custom payment gateway for Paid Memberships Pro integrated with CoinPayments.net for a legal adult content website. Scope of work: Integrate CoinPayments API to create crypto checkout for PMPro subscriptions Support new subscriptions and recurring payments (where supported) Handle CoinPayments IPN/webhooks for: payment confirmed payment failed / expired refunds (if applicable) Sync payment events with PMPro membership status in real time Admin settings for API keys, test/live mode, and basic logs Follow PMPro gateway class structure (clean install/update) Acceptance criteria: I can enable the gateway in PMPro, enter API keys, and complete a full checkout in test mode. On payment confirmation, the user’s membership is activated immediately. On failed/expired payment, access is not granted and status is logged. Webhook events are logged for debugging. Clean, documented code delivered as a plugin. Notes: This is an adult website (18+). If you’re not comfortable with this, please don’t apply. Please share examples of previous payment gateway or PMPro/WooCommerce integrations (crypto or fiat).
