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#

New Branch Created on GitHub

Description:Emit new event when a branch is created.

Version:1.0.10

Key:github-new-branch

View on GitHub

GitHub Overview#

The GitHub API is a powerful gateway to interaction with GitHub's vast web of data and services, offering a suite of endpoints to manipulate and retrieve information on repositories, pull requests, issues, and more. Harnessing this API on Pipedream, you can orchestrate automated workflows that respond to events in real-time, manage repository data, streamline collaborative processes, and connect GitHub with other services for a more integrated development lifecycle.

Trigger Code#

  getSampleTimerEvent, getSampleWebhookEvent,
} from "./common-sample-events.mjs";

};

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
GitHub	`github`	`app`	This component uses the GitHub app.
Repository	`repoFullname`	`string`	Select a value from the drop down menu.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.

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:
