You can use the Session ID parameter to use the same IP between requests. ZenRows will store the IP for 10 minutes if present for the first time. And all subsequent requests with that ID will use the same IP.

But session_id won’t store any other request data, such as session cookies. You will get those back as usual and decide which ones to send on the next request.

You could have several Session IDs running concurrently, there’s no limit to this.
