API Gateway type trigger

Available in VPC

You can add API Gateway type triggers in Cloud Functions > Action > Action details of the NAVER Cloud Platform console. API Gateway is a service that can perform all API-related tasks including API calls, management, and monitoring.

Add trigger

To add an API Gateway type trigger, select API Gateway from the trigger types then configure API Gateway connection information.

Trigger types

API Gateway trigger types vary depending on the action type you want to connect. When connecting web actions or sequence web actions, HTTP type API Gateway triggers are created. When connecting basic actions or sequence actions, webhook type API Gateway triggers are created. Descriptions of each type are as follows:

HTTP type

• Implements REST APIs by directly handling HTTP requests/responses.
• Supports POST, GET, OPTIONS, PUT, DELETE, PATCH, HEAD methods.
• Passes HTTP request headers, parameters, paths, and body values to actions.
• Can receive status codes, headers, and body defined in action code as HTTP responses.

Webhook type

• Can run actions through HTTP requests.
• Supports POST method.
• Supports synchronous (request and reply) and asynchronous (fire and forget) methods from action code returns. For more detailed description, see Query parameters.

Configure API Gateway

Configure API Gateway endpoints to run actions. For detailed API Gateway configuration, see API Gateway user guide.

Product

• A unit for managing multiple APIs. A call domain is provided for each Product.

API

• Unit for managing API specifications and overview where you can define related resources and methods and configure authentication methods.

Resource

• Can configure API URL paths (endpoints).
• For HTTP type, specify resource value as {type+} to reference paths including called sub-resources in action code.
• Cannot select if same method already exists under selected resource.

Stage

• API deployment unit that can be created and operated as development, test, production, or version codes (v 0.0.1).
• Select existing API Gateway deployment Stage or create new one.

API Key authentication

• Calls APIs using your API key when enabled.

Authentication

• Uses IAM authentication provided by NAVER Cloud Platform to protect APIs.
  • NONE: No authentication.
  • IAM: Uses IAM authentication provided by NAVER Cloud Platform.
  • IAM+AUTHORIZATION: Uses NAVER Cloud Platform's IAM user authentication and method-level authorization.

Run trigger

Endpoint

The run endpoint of the API Gateway trigger to run actions is created in the following format.

https://{product_id}.apigw.ntruss.com/{api_name}/{stage_name}/{resource_name}

HTTP request

Request method

HTTP type

• Supports all POST, GET, OPTIONS, PUT, DELETE, PATCH, HEAD methods.

Webhook type

• Supports POST method.

Request headers

HTTP type

• Allows all content types and can reference request headers in action code.

Webhook type

• Allows only application/json content type.

Query parameters

HTTP type

• Passes query parameter values to action code for use.
• To reference query parameters, enable Use HTTP raw data on connected action.

Webhook type

• Cannot reference query parameter values in action code.
• Use following query parameters to adjust API call handling and results during runs:
• blocking
  • true
    • Synchronous (request and reply) request.
    • Receive HTTP response after action completes and action results are passed as response body.
    • Switch to asynchronous call if action exceeds 1 minute.
  • false
    • Asynchronous (fire and forget) request. Default.
    • Return HTTP response immediately regardless of action success or fail with only action history ID (activation ID) in response body.
• result
  • true
    • Pass action code return value as HTTP response body.
  • false
    • Pass action results as HTTP response body. For more information, see Activation run results.

Request body

HTTP type

• For application/json content type, Cloud Functions system controller automatically converts and passes to action parameters in Key/Value format.
• For other content types, enable Use HTTP raw data on connected action for processing.
• Pass text content types as plain text to action and encode binary types in Base64.

Webhook type

• Receives request body JSON data as action runtime parameters.

Events forwarded to action

HTTP request event data is passed as action runtime parameters.

HTTP type

{
    "__ow_headers": {
        "content-type": "application/json"
    },
    "__ow_method": "post",
    "__ow_path": "/",
    "__ow_query": "key1=value1&key2=value2",
    "__ow_body": "eyJhIjogImIiLCAiYyI6IDF9",
}

Webhook type

{
    "name": "Cloud Functions"
}

HTTP response

HTTP type

Defines headers, body, and status code in JSON format in action return values. Cloud Functions system controller converts these to HTTP response format.

• headers: json object with header names as keys and string, number, or boolean values.
• statusCode: HTTP status code. Default is 200 OK. If body is null, empty string (""), or undefined, processes as 204 No Content.
• body: Defines response body using plain text, JSON objects, array strings, and base64 encoded binary data. Default is empty response.

// Content-Type: JSON
{
    statusCode: 200,
    headers: {
        "Content-Type": "application/json"
    },
    body: {"key":"value"}
}

// Content-Type: HTML 
{
    "statusCode": 200,
    "headers": {
        "Content-Type": "text/html"
    },
    "body": "<html><body><h3>hello</h3></body></html>" }
}

// Content-Type: TEXT 
{
    "statusCode": 200,
    "headers": {
        "Content-Type": "text/plain"
    },
    "body": "hello" }
}

// Content-Type: Image 
{
    "statusCode": 200,
    "headers": {
        "Content-Type": "image/png"
    },
    "body": "<base64 encoded string>" }
}

// HTTP Redirect
{
    "statusCode": 302,
    "headers": { 
        "location": "https://www.ncloud.com"
    }
}

// Header cookie settings
{
    "statusCode": 302,
    "headers": { 
        "Set-Cookie": "UserID=Jane; Max-Age=3600; Version=",
        "Content-Type": "text/html"
    },
    "body": "<html><body><h3>hello</h3></body></html>"
}

Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: OPTIONS, GET, DELETE, POST, PUT, HEAD, PATCH
