Account Setup
You need to create two profiles where the first profile will be of the Merchant having a wallet to be able to receive funds and the other profile will be of Processing which will be used for creating the transactions on the merchant's account wallet.

Processor profile
A processor profile is required to manage the transactions of the merchant wallet. This processor profile will help the merchant, to secure his wallet by giving only the required access to the processor on the merchant profile. To configure the processor profile use the below-mentioned link where you can find all the steps to configure the processor profile (linking of merchant profile and processor profile, and after that how to give access to the processor profile of the merchant profile).
** You can also use a merchant profile as a processor profile, but this is advisable to have a separate processor profile to manage the transactions to make your main merchant profile secure.
Processor Profile Configuration
Test profile
To test the merchant account you will have to create a sample/test account which you will use to check if the integration is done properly or not.
