Abstract
Using digital records, telehealth, and Internet-linked devices is becoming more common in healthcare, so making sure API communication is safe and standardised is vital. The study is designed to analyse how well API gateways work, how secure they are and how compliant they are when using JSON Web Tokens (JWT) and OAuth 2.0 with healthcare systems. Secondary data, along with facts from case studies (such as NHS Digital and Babylon Health), were selected for the project to analyse the function of IoT, the storage of tokens and compliance with laws and regulations. Results revealed stronger access control, less risk and better compliance with GDPR and HIPAA. It states that using secure API setups, educating personnel and introducing standard security rules are important for tackling existing issues and getting healthcare systems ready for the future.
Key words: API Gateway, Healthcare Security, JWT, OAuth 2.0, Electronic Health Record (EHR), Data Protection, GDPR, HIPAA, Access Control and Cybersecurity.
