Ah can't seem to edit my post for some reason, and it's formatted the URL

here it is again; domain.whatever/tcbase/teacommerce/PaymentCallbackWithoutOrderId/GoogleCheckout/1

 

 

Hi Tom

Have your remembered to override the AllowCallbackWithoutOrderId and return true? Else it wont allow the server code to call this method

Kind regards
Anders

Hi Anders, 

Yep - I have overridden that bool,

Here's the source of my payment provider thus far,

What is the id of your payment provider? And what is the alias? Could you get me a screenshot of the text you have in the payment providers text area in the Tea Commerce general settings?

Kind regards
Anders

Hi Anders,

<Provider alias="GoogleCheckout" assembly="umbraco-extensions" type="umbraco_extensions.teaCommerceExtensions.GoogleCheckoutPaymentProvider" />

Yes the id is 1 and the alias also looks right.

Have you read this post, maybe that can help you. - look for the "silent post url" - http://anders.burla.dk/umbraco/tea-commerce/using-authorize-net-with-tea-commerce/

Are you running your project locally to debug it?

 

Hi Anders,

Yep - I was using a variant of that post that I found somewhere on Our,

I'm running the project locally, and debugging by attaching visual studio to the IIS process that that the project is running under,

Should that web service method cause the ProcessCallback method to be hit? So if you hit the URL (domain.whatever/tcbase/teacommerce/PaymentCallbackWithoutOrderId/GoogleCheckout/1) in your browser, visual studio should pick up your breakpoints on the ProcessCallback method?

Thanks,

T

This is the code for the PaymentCallbackWithoutOrderId - if you run locally like domain.local/ it should attach - if not - be sure to have build as Debug and you have copied the newest bin and pdb files to your bin directory for the local website.

public static void PaymentCallbackWithoutOrderId( string alias, long paymentMethodId ) {
      IPaymentProvider paymentProviderInstance = Base.GetPaymentProviderInstance( alias );
      if ( paymentProviderInstance.AllowCallbackWithoutOrderId ) {
        PaymentMethod paymentMethod = PaymentMethod.GetPaymentMethod( paymentMethodId );
        if ( paymentMethod != null ) {
          long? orderId = paymentProviderInstance.GetOrderId( HttpContext.Current.Request, paymentMethod.GetSettings( null ) );

          if ( orderId != null )
            Base.PaymentCallback( paymentProviderInstance, orderId.Value );
        }
      }
    }

Kind regards
Anders

Hi Anders,

That's really helpful thanks.

I imagine the orderId lookup is failing in that case which is why my PaymentCallback method isn't being hit. 

Does anything special need to be in the Reqeust in order for it to succeed?

Many Thanks,

Tom

 

Hi Anders,

OK in that case, I will need to write my own version of the PaymentCallbackWithoutOrderId method as I need to do some handshaking with the google server before I can get the orderId that the callback request relates to,

Initial issues with this seem to be that the GetPaymentProviderInstance method doesn't appear to exist within TeaCommerce.Base? And Base.PaymentCallback is looking for two string parameters rather than an IPaymentProvider and a long,

Could this be due to the tea commerce version that I'm running? 

That's proabalby only an accademic question as my new method will only work with / be called by google so I can just code as google needs :)

Thanks,

Tom

Hi Anders,

I'm being a massive spanner,

I had forgotten to public override long? GetOrderId(HttpRequest request, Dictionary<string, string> settings)

is working on a reply...
