VIP User-Agents
Incoming requests made by WordPress VIP Platform features and components can be identified by the User-Agents listed below.
Webhook notifications
VIP Webhooks (+https://vip.wordpress.com)
: A User-Agent that sends outbound webhook Notifications to endpoints configured by customers to receive events.
Let’s Encrypt
Before receiving a Let’s Encrypt TLS certificate, a domain must complete an “ACME challenge” to verify its ownership and hosting location. The following User-Agents are used for some pre-flight validations to verify that the domain is associated with a VIP-hosted application before a provisioning request is sent to the Let’s Encrypt validation service:
WPVIP Let's Encrypt Certificates (+https://docs.wpvip.com/vip-user-agents)
: A User-Agent related to preliminary validations for a domain.WordPress.com; https://acme.wordpress.com
andWordPress.com; https://clitools.wordpress.com
: User-Agents that perform secondary validations for the domain before the request is sent to Let’s Encrypt.
Note: Let’s Encrypt uses a separate user-agent for its validation service, which looks similar to: Mozilla/5.0 (compatible; Let's Encrypt validation server; +https://www.letsencrypt.org)
.
Media imports
WPVIP Media (+https://docs.wpvip.com/vip-user-agents)
: A User-Agent that fetches the publicly accessible archive file provided via the vip import media
VIP-CLI command when importing media files.
