    Dear team,

    I want to integrate jotform to n8n private network. I use provided whitelist IP from this site https://www.jotform.com/help/145-whitelisting-jotform-ip-addresses-and-domains/. I already configure jotform API key into n8n jotform module. But when I try to submit the form, the jotform n8n module doesn't trigger.

    If I change my n8n to public network and submit the form, n8n jotform module successfully triggered

    Please help us to provide the correct IP address jotform to be whitelisted in our n8n private network

    Hi Irwan,

    Thanks for reaching out to Jotform Support. I'm an AI assistant. I'll do my best to help you until someone from the support team is available.

    Regarding your issue with integrating Jotform to your n8n private network, please ensure you whitelist the following Jotform IP address ranges in your network:

    • 152.160.0.0/16
    • 23.251.253.0/26
    • 209.127.149.0/24
    • 209.127.136.0/24
    • 212.47.85.0/24

    These are the official IP ranges Jotform uses, and whitelisting them should allow your n8n module to trigger properly on your private network.

    Give it a try and let us know how it goes.

    Let us know if you have any other questions.

    Hi Irwan,

    While we doesn't guarantee fixed IPs, you can whitelist the following IP ranges for the requests to work:

    • 152.160.0.0/16
    • 23.251.253.0/26
    • 209.127.149.0/24
    • 209.127.136.0/24
    • 212.47.85.0/24

    It’s actually in the same documentation you mentioned. To make sure Jotform can trigger your n8n workflows while running on a private network, you just need to set up your firewall to allow incoming connections from these Jotform’s IP address ranges.

    If you’re seeing a specific error when making a request, check your firewall logs for incoming traffic from Jotform and share the details with us, including the exact IP address the data is coming from. We’ll do a more in-depth investigation and work on finding a solution.

    Once we have a better idea of what’s going on, we’ll be able to come up with a solution.
