Some services only accept requests from IP addresses they already know, such as a partner API, a payment gateway, or your own company’s internal APIs behind a firewall. With static outbound IPs, the apps in your workspace send their outbound traffic from a fixed set of Base44 IP addresses, so you add those addresses to the service’s allowlist once and your apps can reach it.
Static outbound IPs are in beta and available on the Enterprise plan. Only workspace owners and admins can turn them on or off.

​
Understanding what uses a static IP

Static outbound IPs cover 3 kinds of traffic from your workspace:
  • Backend functions: HTTPS requests your apps’ backend functions make to outside services.
  • App sandboxes and Superagents: Requests your apps’ sandboxes and your Superagents make while they work.
  • Connector sign-ins: The sign-in step when a supported connector connects to a service.
What static IPs don’t cover:
  • Direct TCP connections, such as database drivers connecting to Postgres, MySQL, or MongoDB, still leave from shared addresses.
  • Routing through the static IPs can add latency, and can change the location a service sees your requests coming from.

​
Turning on static outbound IPs

Turn the setting on, then allowlist the addresses Base44 shows you in every service your apps call. Allowlist every address and range in the list, so all 3 kinds of traffic can connect. To turn on static outbound IPs:
  1. Click your workspace name at the bottom left of your account.
  2. Click Settings.
  3. Click Governance.
  4. Under Network access, turn on Static outbound IPs.
  5. Click the copy icon next to the list of addresses to copy them all, one per line, then add them to the allowlist of each service your apps call.

Finishing the rollout

Turning the setting on updates every app in your workspace so its traffic goes out through the static IPs. While that runs, the setting shows Enabling… and a progress bar counts the app workers as they update. It shows Enabled once every app is done. Some apps need you to publish them before they can finish. When that happens, Base44 shows how many apps are waiting. Click View apps to see each app and its status:
  • Updating: The app is still switching over.
  • Pending publish: Publish the app and it finishes updating automatically.
  • Failed: The update didn’t go through. Click Retry updates to try again.
If the rollout stops partway, click Restart rollout to start it again.
Publishing an app to finish the rollout also makes any unpublished changes in that app live. Review the app before you publish it.

Turning off static outbound IPs

Turn off Static outbound IPs under Network access in your workspace’s Governance settings. The setting shows Disabling… while your apps switch back to shared addresses, so remove the static addresses from a service’s allowlist only once you no longer need them.
