Hello, I am Hem Chand, a seasoned WordPress Developer with a strong command over WooCommerce and problem-solving. With a whopping 8 years of experience successfully navigating all aspects of web development, I believe I have the expertise you need to address the Rest API issues you're facing. Having worked on platforms such as AWS and Bluehost, I am well-acquainted with the nuance of handling API calls and could quickly find the root cause behind why your "add_to_cart", "update_cart", and "remove_from_cart" API calls stopped functioning specifically post your hosting migration.
Additionally, my domain knowledge extends beyond WooCommerce to HTML5, CSS3, Email templates, CRM Integration, Site Migration amongst others; enabling me to provide holistic solutions tailored uniquely to each project. So let's work together towards resolving this Rest API issue swiftly and successfully; because for me it's more than just about solving the problem - it's about building an eCommerce platform that works flawlessly for your business on AWS.
