SIM Integration - Testing the actual acquirement

[uCommerce]

Hello everybody,

I'm currently doing an integration for the SIM payment and I have encountered some trouble when doing the last testing. I can succesfully authorize a payment in "Test Mode" but when I try to acquire the money I get the following error from your service: "This transaction cannot be accepted.". If I choose to turn off test mode I get the message that my MerchantID is invalid or password is wrong. How do I fix this? Am I doing something wrong when testing?

Regards Martin

You're probably submitting your form to the live servers. Check the post URL and make sure it's set to https://test.authorize.net/gateway/transact.dll (sandbox) and not https://secure.authorize.net/gateway/transact.dll (production). Let me know what happens after you fix that.

Hi again,

I'm using your SDK whether I have set test mode to true. As far I can see it uses test.authorize.net/gateway/transact.dll

Now I'm getting the following response from your service: 

Message: This transaction cannot be accepted.

Response Code: 3

Approved: False

Transaction Code: 0

What's the response sub-code?
