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.

Trigger

Description:Emit new items from an RSS feed
Version:1.2.2
Key:rss-new-item-in-feed

RSS Overview

With the RSS API you have the power to create powerful tools and applications.
RSS is a great way to reliably subscribe to, track and build around your
favorite content sources. Here are some examples of things you can create
using the RSS API:

  • A personal news website to syndicate articles from multiple sources.
  • A custom feed reader to deliver timely notifications of updates and news.
  • A live editorial dashboard to track news, trends and public sentiment.
  • An automated “report bot” to aggregate and report on news topics.
  • A competitor tracking tool to stay on top of industry news.
  • A custom RSS-based search engine or RSS-supported deep learning engine.
  • A live events feed to notify users and followers of new developments.

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.
