## Create channel configuration

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

#### Example request

```json
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`.

```json
"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`:

```json
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"
      ]
    }
  }
}
```

#### Example response

```json
{
  "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.

#### Example request

```json
GET _plugins/_notifications/configs/<config_id>
```

#### Example response

```json
{
  "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.

#### Example request

```json
PUT _plugins/_notifications/configs/<config_id>
{
  "config": {
    "name": "Slack Channel",
    "description": "This is an updated channel configuration",
    "config_type": "slack",
    "is_enabled": true,
    "slack": {
      "url": "https://hooks.slack.com/sample-url"
    }
  }
}
```

#### Example response

```json
{
  "config_id" : "<config_id>"
}
```


## Delete channel configuration

To delete a channel configuration, send a DELETE request to the `configs` resource and specify the `config_id` as a path parameter.

#### Example request

```json
DELETE /_plugins/_notifications/configs/<config_id>
```

#### Example response

```json
{
  "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.

#### Example request

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

#### Example response

```json
{
  "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.

#### Example request

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

#### Example response

```json
{
  "event_source" : {
    "title" : "Test Message Title-0Jnlh4ABa4TCWn5C5H2G",
    "reference_id" : "0Jnlh4ABa4TCWn5C5H2G",

      "config_type" : "slack",
      "config_name" : "sample-id",
      "email_recipient_status" : [ ],
      "delivery_status" : {
        "status_code" : "200",
        "status_text" : """<!doctype html>
<html>

<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>
