As part of Shopify’s upcoming security requirements, we will be enabling IP allowlisting for the MD Integrations Connect Shopify application during the maintenance window: November 17 at 6:00 AM ET.

We have already validated our required outbound IP addresses and will complete final testing against historical traffic before enabling enforcement. We do not anticipate any disruption.

However, in the unlikely event that an IP address is missing from the allowlist, Shopify would temporarily block affected API calls, which could cause a brief interruption to the integration until the configuration is updated.

This change is being made to comply with Shopify’s requirement that all public apps using the Admin API have IP allowlisting enabled by November 20, 2026.

No action is required from your team at this time. We are providing this notice for your awareness and will notify you once the update is complete. If you experience any disruption following this change, please contact us immediately at developers@mdintegrations.com. We will investigate and, if necessary, we will update our allowlist configuration to restore connectivity as quickly as possible.

If you have any questions or concerns, please reach out.
