Event Sources

Traffic Events

Traffic Events fire when traffic transits through your endpoints like processing an HTTP request or TCP connection. Because Traffic Events are often high cardinality, they support the ability to select which fields to capture as well as the ability to specify a CEL filter expression to limit which events are captured.

http_request_complete.v0	Triggers when an HTTP request completes.
tcp_connection_closed.v0	Triggers when a TCP connection to an endpoint closes.

Audit Events

Audit Events fire when you make changes to your account like creating, updating or deleting objects like Domains, API Keys and IP Policies.

Tunnel Credential

tunnel_credential_created.v0

Triggers when a tunnel credential is created

Field	Type	Description
id	string	unique tunnel credential resource identifier
uri	string	URI of the tunnel credential API resource
created_at	string	timestamp when the tunnel credential was created, RFC 3339 format
description	string	human-readable description of who or what will use the credential to authenticate. Optional, max 255 bytes.
metadata	string	arbitrary user-defined machine-readable data of this credential. Optional, max 4096 bytes.
token	string	the credential’s authtoken that can be used to authenticate an ngrok agent. This value is only available one time, on the API response from credential creation, otherwise it is null.
acl	List<string>	optional list of ACL rules. If unspecified, the credential will have no restrictions. The only allowed ACL rule at this time is the bind rule. The bind rule allows the caller to restrict what domains and addresses the token is allowed to bind. For example, to allow the token to open a tunnel on example.ngrok.io your ACL would include the rule bind:example.ngrok.io. Bind rules may specify a leading wildcard to match multiple domains with a common suffix. For example, you may specify a rule of bind:_.example.com which will allow x.example.com, y.example.com, _.example.com, etc. A rule of '\*' is equivalent to no acl at all and will explicitly permit all actions.

tunnel_credential_deleted.v0

Triggers when a tunnel credential is deleted

Field	Type	Description
id	string	unique tunnel credential resource identifier
uri	string	URI of the tunnel credential API resource
created_at	string	timestamp when the tunnel credential was created, RFC 3339 format
