When you work with private integrations (e.g., integrations with self-hosted VCS), you need to add dedicated Crowdin IP addresses to the whitelist to ensure that it operates properly while staying secure. A similar approach is applicable when using Crowdin webhooks. To allow Crowdin to open the pre-configured URLs, add the respective IP addresses to your firewall.
Crowdin uses the following IP address to interact with the integrations:
52.45.158.111/32
Crowdin uses the following IP addresses to send the webhooks from:
3.88.119.237/32
52.72.249.65/32
52.6.250.28/32
For your convenience, you can get the integration and webhook IP addresses in JSON format:
