Starting in November 2018, some outgoing webhook requests from Bitbucket Cloud will be coming from Atlassian’s public IPs in addition to theĀ usual range of addresses.
Most users will not have to do anything to continue receiving webhooks. Users with services behind firewalls may need to update the firewall rules to include the new addresses.
As always, please contact our support team if you have further questions or if you need further assistance.
