Install with Composer
Requires PHP 7.4+, cURL and JSON.
composer require whollycrypto/php-sdkBuild your payment flow
- Create invoices and open the hosted checkout
- Read invoice status, stores and payment methods
- Verify IPN and webhook signatures from the raw body
- Handle API errors and idempotent invoice creation
Three things to connect.
Use your API URL, a project-restricted API credential, and your Project/Store API IDs from Store → Basic. Store keys on your server. Never send them to a browser or include them in a public repository.
Use the store IPN secret for IPN, or the endpoint’s webhook secret for webhooks. Verify the signed raw request before updating orders. A return URL alone is not proof of payment.
