Change language using Accept-Language

To change the language of API responses, you can use the Accept-Language header in your HTTP requests. This header informs the server about your preferred language, and the server will return the response in the selected language.

ℹ️ If Accept-Language is not sent:

If the Accept-Language header is not sent, the response language will be automatically set based on the user's system language. This means that:

• 🟢 If the system language is Persian, the response will be sent in "fa".
• ⚠️ If the system language is not recognized or supported, the response will be sent in Persian by default ("fa").

🔄 Change language manually:
