Putting Cypress aside for a moment. If your application has endpoints you can hit to create test data i.e POST user details to create a new user account: Ask your developers for these endpoint details (URLs, methods, body data etc), and first get it working in Postman, so that you understand what you are doing. Then move back to Cypress and code it using the

cy.request()

command https://docs.cypress.io/api/commands/request Also @gray-kilobyte-89541 has a video on the topic
