Get meta information

Returns an object with properties describing Buildkite.

webhook_ips is a list of IP addresses in CIDR notation that Buildkite uses to send outbound traffic such as webhooks and commit statuses. These are subject to change from time to time. We recommend checking for new addresses daily, and will try to advertise new addresses for at least 7 days before they are used.

Note: The IP addresses shown here are examples. You must query the API to get the current set of IP addresses.

curl "https://api.buildkite.com/v2/meta"
{
  "webhook_ips": ["192.0.2.0/24", "198.51.100.12"]
}

Success response: 200 OK
