New Item in Feed on RSS

Description:Emit new items from an RSS feed

Version:1.2.7

Key:rss-new-item-in-feed

RSS Overview#

The RSS app allows users to automatically fetch and parse updates from web feeds. This functionality is pivotal for staying abreast of content changes or updates from websites, blogs, and news outlets that offer RSS feeds. With Pipedream, you can harness the RSS API to trigger workflows that enable a broad range of automations, like content aggregation, monitoring for specific keywords, notifications, and data synchronization across platforms.

Trigger Code#

Publish Topic Message on QStash

Description:Publish a message to a topic

Version:0.0.1

Key:qstash-publish-topic-message

View on GitHub

QStash Overview#

QStash API offers a secure, scalable, and simple way to manage message queues and defer tasks. Using this API, you can enqueue messages, schedule tasks to run after a delay, and ensure that tasks are executed exactly once, leveraging the power of serverless architecture. With Pipedream's ability to connect to a multitude of services, you can build complex workflows that trigger actions in other apps based on events in QStash, allowing you to automate cross-application business processes with ease.

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
QStash	`qstash`	`app`	This component uses the QStash app.
QStash Topic	`topic`	`string`	Select a value from the drop down menu.
Body	`body`	`object`	The body is forwarded to your endpoints in the HTTP request
Retries	`retries`	`integer`	How often should this messasge be retried in case the destination API is not available.
Deduplication ID	`deduplicationId`	`string`	Provide an ID that will be used to detect duplicate messages. If a duplicate message is detected, the request will be accepted but not enqueued. Learn more.
Content Based Deduplication Enabled	`contentBasedDeduplicationEnabled`	`boolean`	If true, the message content will get hashed and used as deduplication ID. If a duplicate message is detected, the request will be accepted but not enqueued.
Delay	`delay`	`string`	Format for this header is a number followed by duration abbreviation, like `10s`. Available durations are `s` (seconds), `m` (minutes), `h` (hours), `d` (days).
Cron	`cron`	`string`	You can use a tool like Crontab.guru to generate cron expressions.

Action Authentication#

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