Payments Square Connect

This plugin redirects customers to Square Hosted Checkout. Connect Square once under Settings → Payments Square Connect; WooCommerce checkout and Contact Form 7 forms share the same connection.

When you enable Payments Square Connect, the site exchanges data with Square for payments, OAuth, and webhooks.

WooCommerce: enable the gateway under WooCommerce → Settings → Payments and customize the checkout title and description.

Contact Form 7: add the [square_pay] form tag to accept fixed or field-based amounts. Example: [square_pay amount:25.00] or [square_pay amount-field:your-amount] with a matching number field.

External services

This plugin is a client for third-party services. By using it you direct WordPress to contact those services.

• Square (required for payments and connection)
  • What: OAuth, REST API calls (e.g. locations, payment links), and hosted checkout pages.
  • When: When a store admin uses “Connect with Square”, when checkout or a Contact Form 7 payment creates a payment link, and when Square sends webhooks to your site.
  • Endpoints (summary): https://connect.squareup.com or https://connect.squareupsandbox.com (OAuth and API), plus Square’s hosted checkout URLs returned in API responses.
  • Data sent: API requests include OAuth tokens after connection, order or form-derived totals and references needed to create checkout, and webhook payloads as defined by Square.
  • Terms: https://squareup.com/legal – review Square’s developer and seller terms for your region.

Store admins explicitly start OAuth by clicking Connect with Square; customers are sent to Square’s hosted pages only during checkout or after submitting a Contact Form 7 payment form.

Privacy

• Site owners: OAuth and API usage are initiated by an administrator with manage_options. Tokens are stored in the WordPress database (options) like other payment settings.
• Customers: Personal and payment data on hosted checkout is processed by Square under Square’s policies, not by form fields added by this plugin on your site for card entry.
• Logging: Optional WooCommerce logs may record technical details when debug logging is enabled; disable debug in normal production.
• For compliance questions, consult Square’s documentation and your legal advisor; this readme is not legal advice.
