Data output in accordance with their authors

I want to develop an order management service for Next JS and Strapi. I will create accounts for my clients, they will create orders through their account. How to implement the issuance of data when requesting only with orders that the client himself created. It is not possible for a customer to be able to access orders from other customers. I thought that I would be able to implement this through the roles and users of the administration panel, but I found out that through these accounts it would not be possible to receive data through the API in an authorized way. What is the best way to solve this problem?
