Yes, it is possible but in order to receive the project ID and to activate the plugin, you will need to create a Paysera payment collection project. You do not have to collect payments through the Paysera payment collection service but all your deliveries will have to be assigned to a certain payment collection project.
To use our delivery service only, you do not need to wait for your payment collection project to be approved. Just enter Creating project for the delivery service in the mandatory fields. In this case, do not submit your project for review.
However, if you decide to use the Paysera payment collection service for your payment collection you will need to submit your project and wait for it to be approved
