What is a project? Should I create a merchant account for each project?

In our system, a project is your website used to make sales and generate revenue, on which you want to accept payments using our payment solutions. Projects are primarily intended to identify and confirm that requests correctly come from your server to the Payop server.

There is no need to create a merchant account for each website if they refer to one business entity. You can create multiple projects in your account. 

You should register and verify a new merchant account only if you want to submit a new project that belongs to your other company (new entity).
