Request origin did not match allowed origins - Need assistance with CORS issue

[ruelustin5]

Hello ! I am developing a React application and I am trying to integrate it with your public API (https://api.getsling.com/v1/). My application is currently running on http://localhost:3000 during development.

To interact with your API, I need to make cross-origin requests from my frontend. However, when I try to do this, I encounter the following error: "Request origin did not match allowed origins"
This error suggests that my application's origin is not authorized to make requests to your API, which is likely due to CORS (Cross-Origin Resource Sharing) restrictions. Here is an example of the code I am using:

const apiUrl = 'https://api.getsling.com/v1/users';

const fetchUsers = async () => {
  try {
    const response = await fetch(apiUrl, {
      method: 'GET',
      headers: {
        'Authorization': 'Bearer 85c1aad28ac4437c9c4f0e6c4b0f2810',
        'Accept': 'application/json',
      },
    });

    if (response.ok) {
      const users = await response.json();
      console.log('Users:', users);
    } else {
      console.error('Failed to fetch users:', response.status, response.statusText);
    }
  } catch (error) {
    console.error('Error:', error);
  }
};

Any advice or documentation you could provide would be greatly appreciated.

Thank you for your support!
