Hello Vebi,

Thank you for your answer.
Good, that's work !!!

For the payment, in France the most used payment gateway is ATOS SIPS.

I see if the gateway that you propose accept all french banks.

Have a nice day and thank you.

Hello Vebi,

Thanks for your answer.
My redirect url is: olihya.fr.fo/nsy115/administrator/index....=google.authenticate

And do you if the paiement system accept french bank cards?

See you

Olivier

I have done that but the error is the same.

Hello,

I have this error:
Erreur :redirect_uri_mismatch

The redirect URI in the request: olihya.fr.fo/nsy115/administrator/index....=google.authenticate did not match a registered redirect URI

Do you know why?

Best regards
Olivier
