Invalid response

Hi, when i came back from Postfinance to the Shop i got this error.
Invalid response from payment gateway

i did not figure out where the problem is.

do you have any idea?

Most likely your signing hash doesn't match. Did you configure a SHA IN and SHA OUT secret in the postfinance backend? And did you supply these hashes as gateway parameters?

Also make sure, you're working with the correct environment. If you're working with the TEST account, make sure you set $gateway->setTestMode(true)

The SHA IN and SHA OUT is the same in Postfinance and in gateway.
The testmode is set to true.

Did you configure it so that you get transaction feedback? Eg. followed all these steps: https://github.com/bummzack/omnipay-postfinance#configuration-in-the-postfinance-backend

yes

How are you testing this? Plain PHP code, or is the gateway integrated somwhere? Maybe it's easier to discuss this in chat. For example in this gitter channel: https://gitter.im/silverstripe/silverstripe-omnipay… we can start a private conversation from there…
