Custom / headless
Teams that need reliable PayPal checkout without moving commerce to WordPress.
Custom platforms
Your stack. Our payment hub.
The hub runs on WordPress — your storefront does not have to. Connect Laravel, Node, headless, or any app that can sign requests and receive status.
Why this is easy
Keep building where you already sell.
FinPay does not ask you to rebuild the shop in WordPress. The hub is a dedicated payment destination — cart and catalog stay on your platform.
- One payment brain for PayPal, masking, and the store registry
- Your storefront keeps cart, UI, and accounts
- Same hub model as WooCommerce stores
- API Guide inside the product after install
Who it is for
Built for mixed networks
Agencies
Client apps on a shared payment domain with per-store credentials.
Mixed brands
Woo shops and non-WP storefronts under one processor setup.
Docs live in the product

Connection path
Five steps — no code on this page.
Technical contracts ship in the hub API Guide. Here is the path your team follows.
- Set up Payment Hub, license, and PayPal
- Register a custom store and mint credentials
- Health-check and connect from your app
- Sync masked catalog presentation
- Checkout on the hub — status back to you
Status webhook
Your app owns paid — after the signature checks out.
When hub capture completes, FinPay posts a signed status payload to the webhook_url you registered. Return 2xx; retries cover transient failures.
- Verify HMAC before changing order state
- Do not trust browser postMessage as paid
- Same money path as Woo Store-role shops
What you gain
Same outcomes as Woo stores
No WP on every shop
Only the payment hub needs WordPress.
Shared PayPal
One destination across Woo and custom.
Status you can trust
Signed notify with retries when needed.
