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
Reddit	`reddit`	`app`	This component uses the Reddit app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Polling schedule	`timer`	`$.interface.timer`	Pipedream polls Reddit for events on this schedule.
Username	`username`	`string`	The username you'd like to watch.
Number of parents	`numberOfParents`	`integer`	The emitted events will contain the new comment plus the parents of said comment up to the number indicated in this property.
Time filter	`timeFilter`	`string`	Select a value from the drop down menu:`hourdayweekmonthyearall`
Include subreddit details?	`includeSubredditDetails`	`boolean`	If set to `true`, subreddit details will be expanded/included.

Trigger Authentication#

Reddit uses OAuth authentication. When you connect your Reddit account, Pipedream will open a popup window where you can sign into Reddit and grant Pipedream permission to connect to your account. Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any Reddit API.

Pipedream requests the following authorization scopes when you connect your account:

Action#

Send GET Request on HTTP / Webhook

Description:Send an HTTP GET request to any URL. Optionally configure query string parameters, headers and basic auth.

Version:1.1.1

Key:http-get-request

View on GitHub

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.
