Test order creation on localhost

We gently suggest trying out the plugin in a server environment, as it will not be capable of receiving callbacks from SpectroCoin if it will be hosted on localhost. To successfully create an order on localhost for testing purposes, change these 3 lines in CreateOrderRequest.php:

$this->callbackUrl = isset($data['callbackUrl']) ? Utils::sanitizeUrl($data['callbackUrl']) : null;,
$this->successUrl = isset($data['successUrl']) ? Utils::sanitizeUrl($data['successUrl']) : null;,
$this->failureUrl = isset($data['failureUrl']) ? Utils::sanitizeUrl($data['failureUrl']) : null;

To

$this->callbackUrl = "https://localhost.com/";,
$this->successUrl = "https://localhost.com/";,
$this->failureUrl = "https://localhost.com/";

Don't forget to change it back when migrating website to public.

Testing Callbacks

Order callbacks in the SpectroCoin plugin allow your WordPress site to automatically process order status changes sent from SpectroCoin. These callbacks notify your server when an order’s status transitions to PAID, EXPIRED, or FAILED. Understanding and testing this functionality ensures your store handles payments accurately and updates order statuses accordingly.

1. Go to your SpectroCoin project settings and enable Test Mode.
2. Simulate a payment status:
   • PAID: Sends a callback to mark the order as Completed in WordPress.
   • EXPIRED: Sends a callback to mark the order as Failed in WordPress.
3. Ensure your callbackUrl is publicly accessible (local servers like localhost will not work).
4. Check the Order History in SpectroCoin for callback details. If a callback fails, use the Retry button to resend it.
5. Verify that:
   • The order status in WordPress has been updated accordingly.
   • The callback status in the SpectroCoin dashboard is 200 OK.
