Accept Square
without building the integration
Square is a payment platform built around a unified view of online and in-person selling: the same catalogue, inventory and customer records serve a physical till and a web checkout. For merchants who sell in both places that shared ledger is the point, more than the online rates.

What PaymentHood handles for you
A direct Square integration is not just an API call. These are the parts every team ends up rebuilding — and the parts PaymentHood ships already done.
- Credentials
- OAuth access token scoped to the merchant, held server-side in PaymentHood
- Webhook security
- HMAC-signed event notification, verified before an order is released
- Payment verification
- Server-side payment status re-check against the Square API before fulfilment
- Idempotent charge creation, so a retried request never double-charges a customer
- Automatic failover to another configured provider when Square is unreachable
- One reconciliation view across Square and every other provider you run
- Provider credentials never reach the storefront or the customer's browser
- Adding or switching a provider later is a dashboard change, not a re-integration
Use Square on your platform
Install the free PaymentHood plugin for your store, then enable Square in your dashboard.
Connecting Square takes three steps
Open your Square account
Register directly with Square and complete their onboarding. Funds settle from Square into your own bank account — PaymentHood never holds merchant money.
Add the credentials to PaymentHood
Paste your Square API credentials into the PaymentHood dashboard. They are stored server-side and never exposed to your storefront.
Enable it at checkout
Install the PaymentHood plugin for your platform, paste your PaymentHood API key, and Square appears as a payment option. Test in sandbox, then switch to live.
