<h3>External Services</h3>
<p>TejCart connects to the external services below to provide payment processing and merchant onboarding. Data is only sent when the corresponding feature is actively used.</p>
<h4>PayPal</h4>
<p>When a shopper checks out, or a merchant refunds, captures, or voids a transaction, TejCart calls PayPal’s REST API at <code>https://api-m.paypal.com</code> (live) or <code>https://api-m.sandbox.paypal.com</code> (sandbox). Order totals, line items, billing and shipping addresses, and buyer contact information are sent as part of the checkout flow. The plugin also loads the PayPal JavaScript SDK from <code>https://www.paypal.com/sdk/js</code> and the partner-onboarding lightbox from <code>https://www.paypal.com/webapps/merchantboarding/js/lib/lightbox/partner.js</code> on the connect screen.</p>

<li>Terms of service: https://www.paypal.com/us/legalhub/useragreement-full</li>
<li>Privacy policy: https://www.paypal.com/us/legalhub/privacy-full</li>
</ul>
<h4>Google Pay</h4>
<p>When the merchant enables Google Pay, the plugin loads Google’s Pay JavaScript SDK from <code>https://pay.google.com/gp/p/js/pay.js</code> on the cart and checkout pages so the Google Pay button can render and tokenize the shopper’s card.</p>

<li>Privacy policy: https://policies.google.com/privacy</li>
</ul>
<h4>TejCart Partner Onboarding Proxy</h4>
<p>To enable one-click merchant onboarding without shipping partner credentials in the plugin, TejCart calls a proxy at <code>https://tejcart.com/ppcp-seller-onboarding/seller-onboarding.php</code>. The proxy is only contacted while a merchant is connecting or disconnecting a payment account. The plugin sends the merchant’s WordPress admin email, the environment (sandbox or live), a return URL pointing back to the WordPress admin, and the requested product bundle. No shopper data, order data, or API credentials are sent.</p>

</ul>
<h4>Optional bot-protection providers (disabled by default)</h4>
<p>The captcha providers below are opt-in. They are disabled by default and only become active after the merchant explicitly enables a provider under <strong>TejCart > Settings > Security</strong> and supplies their own site key + secret key. When enabled, the plugin verifies a challenge token on the cart, checkout, login, and registration forms by sending the visitor’s IP address and the challenge token to the provider’s <code>siteverify</code> endpoint.</p>
<p><strong>hCaptcha</strong> — When enabled, the plugin calls <code>https://hcaptcha.com/siteverify</code> to verify a challenge response.</p>

<h4>Optional bundled-module services (disabled by default)</h4>
<p>TejCart ships several optional modules that are OFF by default. None of them contacts any third party until a merchant turns the module ON under <strong>TejCart > Modules</strong>, enables a specific provider, and enters that provider’s own API credentials. Each service below is only contacted when its feature is actively used.</p>
<p><strong>Live tax providers (Tax module).</strong> When a provider is enabled, TejCart sends the cart/line totals and the order’s billing/shipping address to calculate tax at checkout and, where supported, to record the finalised transaction.</p>
