I'm integrating Speakatoo’s Text-to-Speech API into my Shopify store but getting a 403 error.

I’m building a Shopify store and working on integrating Speakatoo’s Text-to-Speech service via REST API. Since I couldn’t find an existing plugin, I’m creating one from scratch. However, when I try to call the API endpoint, I keep getting a 403 Forbidden error. I’m using an Apache server—what configurations or permissions should I check to resolve this? Any advice on handling API authentication or headers with Shopify would be helpful!
