GOGetSSL & Postman API Integration

I'm looking for an experienced developer to integrate Postman API with GOGetSSL on a customer portal I'm developing. The primary requirements include:

Create a simplified customer portal where the customer can authenticate and manage their certificates.

Integrate the customer portal with GoGetSSL API ([login to view URL] )

- SSL certificate generation, validation, and revocation functionalities

- User registration and login

- Access to account information

- Order and payment management through the API

The portal design should mirror the minimalist and professional aesthetic of https://www.csebusienss.com. Prospective freelancers should ideally have a background in API integration, website security, and minimalist UI/UX design.
