Authentication
All connector API calls require API key auth or Basic auth. Every mutating request must include the kbn-xsrf header.
kbn-xsrf: true
Required Privileges
Access to connectors is granted based on your privileges to alerting-enabled features. You need all privileges for
Actions and Connectors in Stack Management.
API Reference
Base path: <kibana_url>/api/actions (or /s/<space_id>/api/actions for non-default spaces).

Creating a Connector
Required Fields
Field
Type
Description
name
string
Display name for the connector
connector_type_id
string
The connector type (e.g., .slack, .email, .webhook, .pagerduty, .jira)
config
object
Type-specific configuration (non-secret settings)
secrets
object
Type-specific secrets (API keys, passwords, tokens)
Example: Create a Slack Connector (Webhook)
curl -X POST "https://my-kibana:5601/api/actions/connector/my-slack-connector" \
-H "kbn-xsrf: true" \
-H "Content-Type: application/json" \
-H "Authorization: ApiKey <your-api-key>" \
-d '{
"name": "Production Slack Alerts",
"connector_type_id": ".slack",
"config": {},
"secrets": {
"webhookUrl": "https://hooks.slack.com/services/T00/B00/XXXX"
}
}'
All connector types share the same request structure — only connector_type_id, config, and secrets differ. See the
[Common Connector Type IDs](#common-connector-type-ids) table for available types and their required fields.
Example: Create a PagerDuty Connector
curl -X POST "https://my-kibana:5601/api/actions/connector/my-pagerduty" \
-H "kbn-xsrf: true" \
-H "Content-Type: application/json" \
-H "Authorization: ApiKey <your-api-key>" \
-d '{
"name": "PagerDuty Incidents",
"connector_type_id": ".pagerduty",
"config": {
"apiUrl": "https://events.pagerduty.com/v2/enqueue"
},
"secrets": {
"routingKey": "your-pagerduty-integration-key"
}
}'
Updating a Connector
PUT /api/actions/connector/{id} replaces the full configuration. connector_type_id is immutable — delete and
recreate to change it.
Listing and Discovering Connectors
# Get all connectors in the current space
curl -X GET "https://my-kibana:5601/api/actions/connectors" \
-H "Authorization: ApiKey <your-api-key>"
# Get available connector types
curl -X GET "https://my-kibana:5601/api/actions/connector_types" \
-H "Authorization: ApiKey <your-api-key>"
# Filter connector types by feature (e.g., only those supporting alerting)
curl -X GET "https://my-kibana:5601/api/actions/connector_types?feature_id=alerting" \
-H "Authorization: ApiKey <your-api-key>"
The GET /api/actions/connectors response includes referenced_by_count showing how many rules use each connector.
Always check this before deleting.
Running a Connector (Test)
Execute a connector action directly, useful for testing connectivity.
curl -X POST "https://my-kibana:5601/api/actions/connector/my-slack-connector/_execute" \
-H "kbn-xsrf: true" \
-H "Content-Type: application/json" \
-H "Authorization: ApiKey <your-api-key>" \
-d '{
"params": {
"message": "Test alert from API"
}
}'
Deleting a Connector
curl -X DELETE "https://my-kibana:5601/api/actions/connector/my-slack-connector" \
-H "kbn-xsrf: true" \
-H "Authorization: ApiKey <your-api-key>"
Warning: Deleting a connector that is referenced by rules will cause those rule actions to fail silently. Check
referenced_by_count first.
Terraform Provider
Use the elasticstack provider resource elasticstack_kibana_action_connector.
terraform {
required_providers {
elasticstack = {
source = "elastic/elasticstack"
}
}
}
provider "elasticstack" {
kibana {
endpoints = ["https://my-kibana:5601"]
api_key = var.kibana_api_key
}
}
resource "elasticstack_kibana_action_connector" "slack" {
name = "Production Slack Alerts"
connector_type_id = ".slack"
config = jsonencode({})
secrets = jsonencode({
webhookUrl = "https://hooks.slack.com/services/T00/B00/XXXX"
})
}
resource "elasticstack_kibana_action_connector" "index" {
name = "Alert Index Writer"
connector_type_id = ".index"
config = jsonencode({
index = "alert-history"
executionTimeField = "@timestamp"
})
secrets = jsonencode({})
}
Key Terraform notes:
configandsecretsmust be JSON-encoded strings viajsonencode()
- Secrets are stored in Terraform state; use a remote backend with encryption and restrict state file access
- Import existing connectors:
terraform import elasticstack_kibana_action_connector.my_connector <space_id>/<connector_id> (use default for the
default space)
- After import, secrets are not populated in state; you must supply them in config
Preconfigured Connectors (On-Prem)
For self-managed Kibana, connectors can be preconfigured in kibana.yml so they are available at startup without manual
creation:
xpack.actions.preconfigured:
my-slack-connector:
name: "Production Slack"
actionTypeId: .slack
secrets:
webhookUrl: "https://hooks.slack.com/services/T00/B00/XXXX"
my-webhook:
name: "Custom Webhook"
actionTypeId: .webhook
config:
url: "https://api.example.com/alerts"
method: post
hasAuth: true
secrets:
user: "alert-user"
password: "secret-password"
Preconfigured connectors cannot be edited or deleted via the API or UI. They show is_preconfigured: true and omit
config and is_missing_secrets from API responses.
Networking Configuration
Customize connector networking (proxies, TLS, certificates) via kibana.yml:
# Global proxy for all connectors
xpack.actions.proxyUrl: "https://proxy.example.com:8443"
# Per-host TLS settings
xpack.actions.customHostSettings:
- url: "https://api.example.com"
ssl:
verificationMode: full
certificateAuthoritiesFiles: ["/path/to/ca.pem"]
Connectors in Kibana Workflows
Connectors serve as the integration layer across multiple Kibana workflows, not just alerting notifications:
Workflow
Connector Types
Key Pattern
ITSM ticketing
ServiceNow, Jira, IBM Resilient
Create ticket on active, close on Recovered
On-call escalation
PagerDuty, Opsgenie
trigger on active, resolve on Recovered; always set a deduplication key
Case management
Cases (system action)
UI-only; groups alerts into investigation Cases; can auto-push to ITSM
Messaging / awareness
Slack, Teams, Email
onActionGroupChange for incident channels; summaries for monitoring channels
Audit logging
Index
onActiveAlert to write full alert time-series to Elasticsearch
AI workflows
OpenAI, Bedrock, Gemini, AI Connector
Powers Elastic AI Assistant and Attack Discovery; system-managed
Custom integrations
Webhook
Generic HTTP outbound with Mustache-templated JSON body
For detailed patterns, examples, and decision guidance for each workflow, see workflows.md.
Best Practices
-
Use preconfigured connectors for production on-prem. They eliminate secret sprawl, survive Saved Object imports,
and cannot be accidentally deleted. Reserve API-created connectors for dynamic or user-managed scenarios.
-
Test connectors before attaching to rules. Use the _execute endpoint to verify connectivity. A misconfigured
connector causes silent action failures that only appear in the rule's execution history.
-
**Check referenced_by_count before deleting.** Deleting a connector used by active rules causes those actions to
fail. List connectors and verify zero references, or reassign rules to a new connector first.
-
Use the Email domain allowlist. The xpack.actions.email.domain_allowlist setting restricts which email domains
connectors can send to. If you update this list, existing email connectors with recipients outside the new list will
start failing.
-
Secure secrets in Terraform. Connector secrets (API keys, passwords, webhook URLs) are stored in Terraform state.
Use encrypted remote backends (S3+KMS, Azure Blob+encryption, GCS+CMEK) and restrict access to state files. Use
sensitive = true on variables.
-
One connector per service, not per rule. Create a single Slack connector and reference it from multiple rules.
This centralizes secret rotation and reduces duplication.
-
Use Spaces for multi-tenant isolation. Connectors are scoped to a Kibana Space. Create separate spaces for
different teams or environments and configure connectors per space.
-
Monitor connector health. Failed connector executions are logged in the event log index (.kibana-event-log-*).
Connector failures report as successful to Task Manager but fail silently for alert delivery. Check the
Event Log Index for true failure
rates.
-
Always configure a recovery action alongside the active action. Connectors for ITSM and on-call tools
(ServiceNow, Jira, PagerDuty, Opsgenie) support a close/resolve operation. Without a recovery action, incidents
remain open forever.
-
Use deduplication keys for on-call connectors. Set dedupKey (PagerDuty) or alias (Opsgenie) to
{{rule.id}}-{{alert.id}} to ensure the resolve event closes exactly the right incident. Without this, a new
incident is created every time the alert re-fires.
-
Prefer the Cases connector for investigation workflows. When an alert requires investigation with comments,
attachments, and assignees, use Cases rather than a direct Jira/ServiceNow connector. Cases gives you a native
investigation UI and can still push to ITSM via the Case's external connection.
-
Use the Index connector for durable audit trails. The Index connector writes to Elasticsearch, making alert
history searchable and dashboardable. Pair it with an ILM policy on the target index to control retention.
-
Restrict connector access via Action settings. Use xpack.actions.enabledActionTypes to allowlist only the
connector types your organization needs, and xpack.actions.allowedHosts to restrict outbound connections to known
endpoints.
Common Pitfalls
-
**Missing kbn-xsrf header.** All POST, PUT, DELETE requests require kbn-xsrf: true. Omitting it returns a 400
error.
-
**Wrong connector_type_id.** Use the exact string including the leading dot (e.g., .slack, not slack). Discover
valid types via GET /api/actions/connector_types.
-
**Empty secrets object required.** Even for connectors without secrets (e.g., .index, .server-log), you must
provide "secrets": {} in the create request.
-
Connector type is immutable. You cannot change the connector_type_id after creation. Delete and recreate
instead.
-
Secrets lost on export/import. Exporting connectors via Saved Objects strips secrets. After import, connectors
show is_missing_secrets: true and a "Fix" button appears in the UI. You must re-enter secrets manually or via API.
-
Preconfigured connectors cannot be modified via API. Attempting to update or delete a preconfigured connector
returns 400. Manage them exclusively in kibana.yml.
-
Rate limits from third-party services. Connectors that send high volumes of notifications (e.g., one per alert
every minute) can hit Slack, PagerDuty, or email provider rate limits. Use alert summaries and action frequency
controls on the rule side to reduce volume.
-
Connector networking failures. Kibana must be able to reach the connector's target URL. Verify firewall rules,
proxy settings, and DNS resolution. Use xpack.actions.customHostSettings for TLS issues.
-
License requirements. Some connector types require a Gold, Platinum, or Enterprise license. Check the
minimum_license_required field from GET /api/actions/connector_types. A connector that is
enabled_in_config: true but enabled_in_license: false cannot be used.
-
Terraform import does not restore secrets. When importing an existing connector into Terraform, the secrets are
not read back from Kibana. You must provide them in your Terraform configuration, or the next terraform apply will
overwrite them with empty values.

Note: Use GET /api/actions/connector_types to discover all available types on your deployment along with their
exact minimum_license_required values. Connector types for XSOAR, Jira Service Management, and MCP are available but
may not appear in older API spec versions.
Examples
Create a Slack connector: "Set up Slack notifications for our alerts." POST /api/actions/connector with
connector_type_id: ".slack" and secrets.webhookUrl. Use the returned connector id in rule actions.
Test a connector before attaching to rules: "Verify the PagerDuty connector works."
POST /api/actions/connector/{id}/_execute with a minimal params object to confirm connectivity before adding to any
rule.
Audit connector usage before deletion: "Remove the old email connector." GET /api/actions/connectors, inspect
referenced_by_count — if non-zero, reassign the referencing rules first, then DELETE /api/actions/connector/{id}.
Guidelines
- Include
kbn-xsrf: trueon every POST, PUT, and DELETE; omitting it returns 400.
connector_type_idis immutable — delete and recreate to change connector type.
- Always pass
"secrets": {}even for connectors with no secrets (e.g.,.index,.server-log).
- Check
referenced_by_countbefore deleting; a deleted connector silently breaks all referencing rule actions.
- Connectors are space-scoped; prefix paths with
/s/<space_id>/api/actions/for non-default Kibana Spaces.
- Secrets are write-only: not returned by GET and stripped on Saved Object export/import; always re-supply after import.
- Test every new connector with
_executebefore attaching to rules; connector failures in production are silent.
