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:Exposes an HTTP API for scheduling messages to be emitted at a future time
Version:0.3.1
Key:pipedream-new-scheduled-tasks

Pipedream Overview

Pipedream is an API that allows you to build applications that can connect to
various data sources and processes them in real-time. You can use Pipedream to
create applications that can perform ETL (Extract, Transform, and Load) tasks,
as well as to create data-driven workflows.

Some examples of applications you can build using the Pipedream API include:

  • An application that can extract data from a database, transform it, and then
    load it into another database.
  • An application that can monitor a data source for changes, and then trigger a
    workflow in response to those changes.
  • An application that can poll an API for new data, and then process that data
    in real-time.

Retriever Overview

The Retriever API is designed for automating contact information retrieval, enriching your CRM data, or building lead generation tools. By integrating it with Pipedream, you can strategically extract valuable data and automate workflows for marketing, sales, or customer support. Pipedream’s serverless platform enables you to connect Retriever with hundreds of other apps, triggering actions based on new data, or updating systems in real-time.
