Payment with Multibanco via Paygate form interface
Multibanco offers two ways of merchant integration with Paygate. Based on the desired way chosen by the merchant for the second solution the merchant should notify Computop to undertake appropriate setup. First and default option is by redirection where the client after choosing the payment method Multibanco is getting re-directed to a predefined landing page showing the relevant information such as Amount, CompanyID and Reference that should be then input on its own Online banking portal or when present at the ATM. Second option is that after choosing the payment method the merchant have a direct request-response call with Paygate and he is responsible of showing the information that he gets in the response in its own landing page created to look like his shop layout. In the response for second option Paygate will send to the merchant the two additional parameters CompanyID and Reference.
