I need my Shopify store fully connected to the eSIMAccess.com REST/JSON API (docs: https://docs.esimaccess.com/) so every data plan offered by the provider appears in Shopify and stays perfectly in sync. Strong experience with API integrations (REST/JSON). Error handling, retries, and clean, well-documented code. When you respond, include: • A concise summary (and links or screenshots) of comparable Shopify + third-party API integrations you have delivered—ideally work that involved esimaccess.com. • Your proposed timeline and fixed price broken into logical milestones. • References or live stores that prove your expertise. Only developers who have already tackled this specific API—or an equally complex telecom data-plan feed—should apply. I will review portfolios carefully and schedule a quick technical chat before awarding the project.
