Getting Started

This API uses OAuth for authentication, which is more involved than a simple API key but provides better security, especially when accessing user data.

Register your app — Create an application on the API provider's developer portal to get a Client ID and Client Secret.
Implement the OAuth flow — Redirect users to the provider's authorization page, where they grant permission to your app.
Exchange the code — After authorization, you'll receive a code that you exchange for an access token.
Use the token — Include the access token in the Authorization header of your API requests.

OAuth is commonly used by APIs that access personal data (like social media accounts). Many libraries exist to simplify the OAuth flow in every major programming language.

CORS Support

This API supports CORS (Cross-Origin Resource Sharing), meaning you can call it directly from browser-based JavaScript applications without running into cross-origin errors.

Quick Example

// Using cURL
curl -H "Authorization: Bearer YOUR_ACCESS_TOKEN" https://developers.bb.com.br/home

// Using JavaScript fetch()
const response = await fetch(apiUrl, {
  headers: { 'Authorization': 'Bearer YOUR_ACCESS_TOKEN' }
});
const data = await response.json();
