Hi,
i am currently trying to implement adyen payment gateway in my hikashop.
i always get an error: merchant signature is incorrect
searching the web, it looks like, there is a problem with sha1 vs. sha256 !?!! issue?
it should be pretty simple to set up the hika plugin:
generate a skin in the adyen settings, and enter the merchant account, hmac key and skin code in the hika plugin.
but when i try to make a payment, i always get an error, merchant signature is incorrect.
any idea?
thanks.

Hello,

You're the first one to speak about this kind of issue, from what you said I see only 2 solutions :
- Check ALL your merchant references, especially that must match with your Ayden.com Merchant account.
It's obvious advice, but that have to be told.
- OR Ayden have change is signature processing, on our side it's actually an Hmac Sha1, and maybe they move to Sha256.
=> For be sure try this :
- Open your plugin file, adyen.php and replace ALL sha1 for sha256, and process new tests.
Awaiting news from you to update our Adyen plugin.

Regards

Hi Philip,

a) i checked the settings (see attachment).
there is the merchant account, skin-code and hmac key. Anything else to check?
b) i tested to change the sha1 to sha256, but no success.

any further ideas?
thanks.

Hello,

I remove your screenshot, in order to don't display your Adyen secret references.
For any other idea, did you contact Adyen support ?
Maybe they have a view on your unsuccesful test, like with an error code or message ?
Or you have in your Adyen account some informations about your tests ?

Awaiting news from you.
Regards

here, on the adyen testsite, you can see, that the merchant signature is calculated incorrect.
that site also shows, that sha1 should be ok, so no need to change to sha256.
which variables are used to calculate the signature? merchant account, hmac, skincode?

no reply from adyen support so far ..

Hi,
now the support guy from adyen changed my account to sha1 manually, and now its working!!!
so:
a) it seems like to change sha1 to sha256 in the adyen.php is not sufficient to solve it, because i tried that solution.
b) it seems like, the customer is not able to change the adyen settings back to sha1, because there is no option in the adyen backend.

solved.
