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 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.

Trigger Authentication

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

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

Browserless Overview

Browserless allows you to build websites and applications that can be used
without a web browser. This means that you can create apps that can be used
offline, or that can be used on devices that don't have a web browser
installed.

Some examples of things that you can build using Browserless are:

  • A website that can be used without a web browser
  • An app that can be used offline
  • A app that can be used on devices that don't have a web browser installed
