Payment Configuration

Payment Configuration

The plugin supports two payment methods: Square (card payments) and Venmo (manual transfer).

Square Setup

Prerequisites

• A Square Developer account
• SSL certificate on your WordPress site (required for PCI compliance)

Configuration

1. Create an application in the Square Developer Dashboard
2. Copy your Application ID and Access Token
3. Find your Location ID in the Square Dashboard under Locations
4. Go to Settings → Caswell Booking → Square and enter:

Field	Description
Application ID	Square app ID (starts with sandbox-sq0... or sq0...)
Location ID	Your Square location ID
Access Token	Encrypted on save
Sandbox Mode	Enable for testing (uses Square sandbox environment)

Sandbox Testing

With sandbox mode enabled:

• Uses sandbox.web.squarecdn.com SDK
• Payments go to connect.squareupsandbox.com
• Use Square's test card numbers

Pricing

Session prices are configured in Settings → Venmo tab (shared pricing for both methods) and Settings → Business Info → Service Pricing (for homepage display).

Venmo Setup

Venmo is a "pay later" option — the booking is created with payment_status = 'unpaid', and the client is shown Venmo details after confirmation.

Configuration

Go to Settings → Caswell Booking → Venmo:

Field	Description
Venmo Username	Your @username (shown to clients)
Price — 30/60/90 min	Amount shown in the Venmo deep link

Client Flow

1. Client selects "Pay via Venmo" during booking
2. Booking is created as unpaid
3. Confirmation screen shows the Venmo username and a deep link to the Venmo app
4. Client sends payment manually

Refunds

Square payments can be refunded programmatically via Caswell_Booking_Handler::refund_square(). The payment ID is stored with each booking for this purpose.
