[HyperpayPlugin/getCheckoutID] HttpException: 400: {"result":{"code":"200.300.404","description":"invalid or missing parameter","parameterErrors":[{"name":"entityID","value":"my test entityId","message":"is not an allowed parameter"}]},"buildNumber":"01bd52148ce2598807fd43a4d36810f974eb028e@2022-04-01 07:48:59 +0000","timestamp":"2022-04-02 12:23:45+0000","ndc":"5B57484A2A9E90A0DF85D8C86427F6F1.uat01-vm-tx04"}
there is my code:

class TestConfig implements HyperpayConfig {
String creditcardEntityID = 'test entityId';
String madaEntityID = '';
Uri checkoutEndpoint = _checkoutEndpoint;
Uri statusEndpoint = _statusEndpoint;
PaymentMode paymentMode = PaymentMode.test;
}

Uri _checkoutEndpoint = Uri(scheme: 'https', host: _host, path: '/v1/checkouts', queryParameters: {
'currency': 'JOD',
'paymentType': 'DB',
});

The error is coming from HyperPay's backend, and is indicating one of the parameters you sent in your request isn't allowed, perhaps you need to check with HyperPay support.

@pr-Mais
i contacted with hyper pay support and we figured out that the problem not from backend side
can you show me how to send parameters to the backend side using this package?

Check the example app I posted above, all additional parameters can be sent in additionalParams. Entity IDs are configured as part of your HyperpayConfig
https://github.com/nyartech/hyperpay/blob/main/example/lib/constants.dart

The plugin currently only supports Credit Cards (Master, VISA) and MADA entities.
