Create channel configuration

To create a notification channel configuration, send a POST request to the configs resource.

Sample Request

POST /_plugins/_notifications/configs/
{
  "config_id": "sample-id",
  "name": "sample-name",
  "config": {
    "name": "Sample Slack Channel",
    "description": "This is a Slack channel",
    "config_type": "slack",
    "is_enabled": true,
    "slack": {
      "url": "https://sample-slack-webhook"
    }
  }
}

The create channel API operation accepts the following fields in its request body:

Field Data type Description Required
config_id String The configuration’s custom ID. No
config Object Contains all relevant information, such as channel name, configuration type, and plugin source. Yes
name String Name of the channel. Yes
description String The channel’s description. No
config_type String The destination of your notification. Valid options are sns, slack, chime, webhook, smtp_account, ses_account, email_group, and email. Yes
is_enabled Boolean Indicates whether the channel is enabled for sending and receiving notifications. Default is true. No

The create channel operation accepts multiple config_types as possible notification destinations, so follow the format for your preferred config_type.

"sns": {
  "topic_arn": "<arn>",
  "role_arn": "<arn>" //optional
}
"slack": {
  "url": "https://sample-chime-webhoook"
}
"chime": {
  "url": "https://sample-amazon-chime-webhoook"
}
"webhook": {
      "url": "https://custom-webhook-test-url.com:8888/test-path?params1=value1&params2=value2"
}
"smtp_account": {
  "host": "test-host.com",
  "port": 123,
  "method": "start_tls",
  "from_address": "test@email.com"
}
"ses_account": {
  "region": "us-east-1",
  "role_arn": "arn:aws:iam::012345678912:role/NotificationsSESRole",
  "from_address": "test@email.com"
}
"email_group": { //Email recipient group
  "recipient_list": [
    {
      "recipient": "test-email1@test.com"
    },
    {
      "recipient": "test-email2@test.com"
    }
  ]
}
"email": { //The channel that sends emails
  "email_account_id": "<smtp or ses account config id>",
  "recipient_list": [
    {
      "recipient": "custom.email@test.com"
    }
  ],
  "email_group_id_list": []
}

The following example demonstrates how to create a channel using email as a config_type:

POST /_plugins/_notifications/configs/
{
  "id": "sample-email-id",
  "name": "sample-name",
  "config": {
    "name": "Sample Email Channel",
    "description": "Sample email description",
    "config_type": "email",
    "is_enabled": true,
    "email": {
      "email_account_id": "<email_account_id>",
      "recipient_list": [
        "sample@email.com"
      ]
    }
  }
}

Sample Response

{
  "config_id" : "<config_id>"
}

Get channel configuration

To get a channel configuration by config_id, send a GET request and specify the config_id as a path parameter.

Sample Request

GET _plugins/_notifications/configs/<config_id>

Sample Response

{
  "start_index" : 0,
  "total_hits" : 1,
  "total_hit_relation" : "eq",
  "config_list" : [
    {
      "config_id" : "sample-id",
      "last_updated_time_ms" : 1652760532774,
      "created_time_ms" : 1652760532774,
      "config" : {
        "name" : "Sample Slack Channel",
        "description" : "This is a Slack channel",
        "config_type" : "slack",
        "is_enabled" : true,
        "slack" : {
          "url" : "https://sample-slack-webhook"
        }
      }
    }
  ]
}

Update channel configuration

To update a channel configuration, send a POST request to the configs resource and specify the channel’s config_id as a path parameter. Specify the new configuration details in the request body.

Sample Request

PUT _plugins/_notifications/configs/<config_id>
{
  "config": {
    "name": "Slack Channel",
    "description": "This is an updated channel configuration",
    "config_type": "slack",
    "is_enabled": true,
    "slack": {

    }
  }
}

Sample Response

{
  "config_id" : "<config_id>"
}

Sample Request

DELETE /_plugins/_notifications/configs/<config_id>

Sample Response

{
  "delete_response_list" : {
  "<config_id>" : "OK"
  }
}

You can also submit a comma-separated list of channel IDs you want to delete, and OpenSearch deletes all of the specified notification channels.

Sample Request

DELETE /_plugins/_notifications/configs/?config_id_list=<config_id1>,<config_id2>,<config_id3>...

Sample Response

{
  "delete_response_list" : {
  "<config_id1>" : "OK",
  "<config_id2>" : "OK",
  "<config_id3>" : "OK"
  }
}

Send test notification

To send a test notification, send a GET request to /feature/test/ and specify the channel configuration’s config_id as a path parameter.

Sample Request

GET _plugins/_notifications/feature/test/<config_id>

Sample Response

{
  "event_source" : {
    "title" : "Test Message Title-0Jnlh4ABa4TCWn5C5H2G",
    "reference_id" : "0Jnlh4ABa4TCWn5C5H2G",
    "severity" : "info",
    "tags" : [ ]
  },
  "status_list" : [
    {

      "config_type" : "slack",
      "config_name" : "sample-id",
      "email_recipient_status" : [ ],
      "delivery_status" : {
        "status_code" : "200",
        "status_text" : """<!doctype html>
<html>
<head>
</head>
<body>
<div>
    <h1>Example Domain</h1>
    <p>Sample paragraph.</p>
    <p><a href="sample.example.com">TO BE OR NOT TO BE, THAT IS THE QUESTION</a></p>
