Login Methods

There are two ways to connect an account:
  1. Credential-based login — provide email + password. If 2FA is enabled, you’ll receive a checkpoint_required status and need to call /v2/checkpoint.
  2. Token-based login — provide a login_token directly. The token is encrypted and stored securely. No 2FA step needed.

​
Notes

  • The account_id returned is permanent — store it and reuse it for all API calls
  • Tokens are encrypted at rest using AES-256
  • If you receive checkpoint_required, use the /v2/checkpoint endpoint to complete verification
  • The country parameter determines which proxy is used for the connection
  • Each platform may require different parameters (e.g. WhatsApp uses phone_number)
