Request Body

Parameter	Type	Required	Description
username	string	required	Account username or email
password	string	required	Account password
twoFactorSecret	string	optional	TOTP secret (min 16 chars) for accounts with 2FA enabled. Used to auto-generate 2FA codes.
proxy	string	required	Proxy in format 'hostname:port@username:password'. Required for all login requests.
country	string	required	Assigned ISO 3166-1 alpha-2 code for the public IP used to reach X. Use the proxy exit country (for example, 'US'). All assigned codes are accepted, and input is normalized to uppercase.

Country and proxy matching

country identifies the public IP location used for the X login request, not the account's profile country. Set it to the proxy's exit country and keep the same proxy for the complete login attempt. For example, use US for a proxy that exits in the United States. A mismatched country and proxy location can cause X to reject the login.

Code Examples

const body = {
  username: 'yourUsername',
  password: 'yourPassword',
  proxy: 'proxy.example.com:8080@proxyUser:proxyPass',
  country: 'US'
};

const response = await fetch('https://api.tweetapi.com/tw-v2/auth/login', {
  method: 'POST',
  headers: {
    'X-API-Key': 'YOUR_API_KEY',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify(body)
});

const data = await response.json();
console.log(data);
