A Dedicated Sticky IP ensures that a specific profile uses by default the same IP address, reserved exclusively for that profile. This is helpful when IP consistency is required across sessions.
1

Enable sticky IP in profile creation

Use the Create Profile API to create a profile with a dedicated sticky IP by setting:
{
  "dedicated_sticky_ip": true
}
This allocates a dedicated IP that is not shared with other profiles.
2

Start sessions with the reserved IP

Any browser session started using this profile will automatically use the reserved sticky IP.
3

Override the IP with a custom proxy (optional)

To override the default sticky IP, set the proxy field when using the Start Browser Session API.
