Member payments that unlock access automatically
When a member pays, our webhook tells your system to unlock the subscription or top up the balance — no one has to check anything by hand.
The problem
Sound familiar?
Payments that need manual confirmation
Users send a screenshot, staff check it, and only then is access granted. Slow for users, costly for you.
Want to get paid without building a UI
You just need to collect a payment, not build and maintain a checkout page.
Lost webhooks, missing access
A network blip drops a notification, and a paying user ends up without access.
How PQPA helps
What changes with PQPA
- 01
Webhooks that drive fulfilment
On arrival we call your webhook; once the signature checks out, grant the membership or add the balance.
- 02
Hosted checkout and invoices (coming soon)
Create an invoice, send the hosted checkout link, and get paid without writing any frontend code.
- 03
Missed webhooks can be replayed
Failed deliveries are logged and can be re-sent from the dashboard or via API.
Capabilities
What you get
Signed webhooks with replay
HMAC-SHA256 signatures you can verify; any missed webhook can be re-sent.
A dedicated deposit address per user
Long-lived, user-specific addresses, so every deposit is matched to the right account.
Hosted checkout and invoices
Get paid without building a payment UI: create an invoice and send the payer a hosted checkout link.
Merchant and app isolation
Separate books per merchant and per app, so funds from different business lines never mix.
Automatic sweeping and gas top-up
Funds sitting on user addresses are swept to your collection wallet, with gas topped up automatically when needed.
