How to pass parameters to a MobileFirst HTTP adapter - soap

Question

I need to run an HTTP adapter to access a SOAP WSDL service. It has 2 fields userid and password.
I have auto generated the adapter by discover backend services. Can anyone guide me to how to pass values from adapter initially to access the service?

To invoke the adapter and pass the parameters you need to call WL.Client.invokeProcedure in your particular case you can use
var invocationData = {
adapter: 'YOUR_ADAPTER_NAME',
procedure: 'userlogin_ep_process',
parameters: {
process: {
username: 'YOUR_USERNAME',
userpwd: 'YOUR_PASSWORD'
}
}
};
WL.Client.invokeProcedure(invocationData, {
onSuccess: yourSuccessFunction,
onFailure: yourFailureFunction
});
