Details#

This integration uses pre-built, source-available components from Pipedream's GitHub repo. These components are developed by Pipedream and the community, and verified and maintained by Pipedream.

To contribute an update to an existing component or create a new component, create a PR on GitHub. If you're new to Pipedream component development, you can start with quickstarts for trigger span and action development, and then review the component API reference.

New Requests (Payload Only) on HTTP / Webhook

Description:Get a URL and emit the HTTP body as an event on every request

Version:0.1.1

Key:http-new-requests-payload-only

HTTP / Webhook Overview#

Build, test, and send HTTP requests without code using your Pipedream workflows. The HTTP / Webhook action is a tool to build HTTP requests with a Postman-like graphical interface.

Point and click HTTP requests

Define the target URL, HTTP verb, headers, query parameters, and payload body without writing custom code.

$A screenshot of Pipedream's HTTP Request Configuration interface with a GET request type selected. The request URL is set to 'https://api.openai.com/v1/models'. The 'Auth' tab is highlighted, indicating that authentication is required for this request. In the headers section, there are two headers configured: 'User-Agent' is set to 'pipedream/1', and 'Authorization' is set to 'Bearer {{openai_api_key}}', showing how the OpenAI account's API key is dynamically inserted into the headers to handle authentication automatically.$

Here's an example workflow that uses the HTTP / Webhook action to send an authenticated API request to OpenAI.

Focus on integrating, not authenticating

This action can also use your connected accounts with third-party APIs. Selecting an integrated app will automatically update the request’s headers to authenticate with the app properly, and even inject your token dynamically.

Pipedream integrates with thousands of APIs, but if you can’t find a Pipedream integration simply use Environment Variables in your request headers to authenticate with.

Compatible with no code actions or Node.js and Python

The HTTP/Webhook action exports HTTP response data for use in subsequent workflow steps, enabling easy data transformation, further API calls, database storage, and more.

Response data is available for both coded (Node.js, Python) and no-code steps within your workflow.

Trigger Code#

import http from "../../http.app.mjs";

// Core HTTP component
// Returns a 200 OK response, emits the HTTP payload as an event
export default {
  key: "http-new-requests-payload-only",
  name: "New Requests (Payload Only)",
  // eslint-disable-next-line
  description: "Get a URL and emit the HTTP body as an event on every request",
  version: "0.1.1",
  type: "source",
  props: {
    // eslint-disable-next-line
    httpInterface: {
      type: "$.interface.http",
      customResponse: true,
    },
    http,
  },
  async run(event) {
    const { body } = event;
    this.httpInterface.respond({
      status: 200,
      body,
    });
    // Emit the HTTP payload
    this.$emit({
      body,
    });
  },
};

Trigger Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.

Label	Prop	Type	Description
N/A	`httpInterface`	`$.interface.http`	This component uses `$.interface.http` to generate a unique URL when the component is first instantiated. Each request to the URL will trigger the `run()` method of the component.
HTTP / Webhook	`http`	`app`	This component uses the HTTP / Webhook app.

Trigger Authentication#

The HTTP / Webhook API does not require authentication.

AWS Overview#

The AWS API unlocks endless possibilities for automation with Pipedream. With this powerful combo, you can manage your AWS services and resources, automate deployment workflows, process data, and react to events across your AWS infrastructure. Pipedream offers a serverless platform for creating workflows triggered by various events that can execute AWS SDK functions, making it an efficient tool to integrate, automate, and orchestrate tasks across AWS services and other apps.

Action Code#

import common from "../../common/common-dynamodb.mjs";
import {
  toSingleLineString,
  attemptToParseJSON,
} from "../../common/utils.mjs";

export default {
  ...common,
  key: "aws-dynamodb-query",
  name: "DynamoDB - Query",
  description: toSingleLineString(`
    The query operation finds items based on primary key values.
    [See docs](https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/clients/client-dynamodb/classes/querycommand.html)
  `),
  version: "0.5.1",
  type: "action",
  props: {
    aws: common.props.aws,
    region: common.props.region,
    tableName: common.props.tableName,
    keyConditionExpression: common.props.keyConditionExpression,
    projectionExpression: common.props.projectionExpression,
    expressionAttributeNames: common.props.expressionAttributeNames,
    expressionAttributeValues: common.props.expressionAttributeValues,
  },
  async run({ $ }) {
    const params = {
      TableName: this.tableName,
      KeyConditionExpression: this.keyConditionExpression,
      ProjectionExpression: this.projectionExpression,
      ExpressionAttributeNames: attemptToParseJSON(this.expressionAttributeNames),
      ExpressionAttributeValues: attemptToParseJSON(this.expressionAttributeValues),
    };

    const response = await this.aws.pagination(
      this.query,
      params,
      "ExclusiveStartKey",
      "LastEvaluatedKey",
    );

    const s = response.Items.length === 1
      ? ""
      : "s";
    $.export("$summary", `Query returned ${response.Items.length} item${s}`);
    return response;
  },
};

Action Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI.

Label	Prop	Type	Description
AWS	`aws`	`app`	This component uses the AWS app.
AWS Region	`region`	`string`	Select a value from the drop down menu.
Table Name	`tableName`	`string`	Select a value from the drop down menu.
Key Condition Expression	`keyConditionExpression`	`string`	The condition that specifies the key values for items to be retrieved by the Query action. Example: `partitionKeyName = :partitionkeyval AND sortKeyName = :sortkeyval` See the docs
Projection Expression	`projectionExpression`	`string`	A string that identifies one or more attributes to retrieve from the specified table or index. If no attribute names are specified, then all attributes will be returned. If any of the requested attributes are not found, they will not appear in the result.
Expression Attribute Names	`expressionAttributeNames`	`string`	One or more substitution tokens for attribute names in an expression. Example: `{ "#execs": "execs" }` See the docs
Expression Attribute Values	`expressionAttributeValues`	`string`	One or more values that can be substituted in an expression. Use the : (colon) character in an expression to dereference an attribute value. Example: `{ ":echo": { "S": "echo" }, ":oneh": { "N": "100" } }` See the docs

Action Authentication#

AWS uses API keys for authentication. When you connect your AWS account, Pipedream securely stores the keys so you can easily authenticate to AWS APIs in both code and no-code steps.

Follow the AWS Instructions for creating an IAM user with an associated access and secret key.

As a best practice, attach the minimum set of IAM permissions necessary to perform the specific task in Pipedream. If your workflow only needs to perform a single API call, you should create a user and associate an IAM group / policy with permission to do only that task. You can create as many linked AWS accounts in Pipedream as you'd like.

Enter your access and secret key below.
