Adyen domain and IP addresses

Ensure that your network configuration allows communication with Adyen's servers.

Depending on your network and security requirements, you might need to add our network to your firewall's allowlist to receive webhook events from us.

We do not provide a list of IP addresses. IP addresses change over time due to various reasons, such as ISP configuration changes. This can lead to disruptions in receiving webhooks if IP addresses are hard-coded.

To make sure you can communicate with our network, you can either:

  • Use a domain allowlist. Include our domain if your network configuration allows domain allowlisting.
  • Systematically resolve our IP addresses. Perform DNS lookup for We recommend that you check every hour. However, if you choose to hardcode the resolved IP addresses to an allowlist, you still run the risk of a disruption if IP addresses change during the DNS lookup interval.
