API Gateway REST API endpoint response 403 error

As you mentioned, when you send a request using local test tools, it goes through, but when you send a request from your laptop, you are getting 403 errors. This might be because Cloudflare has some firewall rules blocking your request. I suggest checking with their support to assist you with troubleshooting. You can enable API Gateway access logging to identify your request ID and public IP. You can also reach out to the AWS Support team for further assistance.

To address the issue you're encountering, here are a few steps and suggestions that might help resolve the discrepancy:

• Check Cloudflare Firewall Rules: The target website may have Cloudflare firewall rules that block requests from certain IP ranges, including AWS IP addresses. Contact the website's administrator or Cloudflare support to review and adjust these firewall rules if necessary.

• Enable API Gateway Access Logging: Enable logging in API Gateway to get detailed information about the requests being made. This can help identify specific issues such as the exact IP addresses being blocked.

• Modify Request Headers: The message "Enable JavaScript and cookies to continue" suggests that the target website might be using Cloudflare's bot protection features, which can block requests that do not resemble those from a typical browser. Try modifying your request headers to mimic a real browser, including User-Agent, Accept, and other relevant headers.

• Use a Proxy: Consider routing your API requests through a proxy server that is not blocked by Cloudflare. This can help bypass any IP-based restrictions.

• Check for JavaScript and Cookies Requirement: Since the response mentions enabling JavaScript and cookies, it might be necessary to use a headless browser or a tool like Puppeteer to handle the request, which can process JavaScript and cookies.

• Contact AWS Support: Reach out to AWS Support for assistance. They might provide additional insights or solutions for dealing with this issue.

• Rate Limiting and CAPTCHA: Verify if the website has rate limiting or CAPTCHA challenges that are preventing your API requests. Implementing delays between requests or solving CAPTCHA challenges programmatically (if allowed) might be necessary.
