Getting Started#

This integration creates a workflow with a PolygonScan trigger and GitHub action. When you configure and deploy the workflow, it will run on Pipedream's servers 24x7 for free.

Select this integration
Configure the New Transaction Posted trigger
1. Connect your PolygonScan account
2. Configure Address
3. Configure timer
Configure the Create Branch action
1. Connect your GitHub account
2. Select a Repository
3. Configure Branch Name
4. Optional- Select a Source Branch
Deploy the workflow
Send a test event to validate your setup
Turn on the trigger

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 Transaction Posted on PolygonScan

Description:Emit new event when a new transaction is posted on the PolygonScan network for a specific address.

PolygonScan Overview#

The PolygonScan API provides access to blockchain data from the Polygon network. It allows for querying of blocks, transactions, and wallet addresses, among other data points. With Pipedream, you can integrate this API to automate monitoring, alerting, and data analysis tasks. You can leverage Pipedream's serverless platform to create workflows that react to events on the Polygon network in real-time, without having to manage infrastructure or write complex backend code.

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
PolygonScan	`polygonscan`	`app`	This component uses the PolygonScan app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Address	`address`	`string`	The address to watch for new transactions.
	`timer`	`$.interface.timer`

Trigger Authentication#

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

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.

Action Code#

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
GitHub	`github`	`app`	This component uses the GitHub app.
Repository	`repoFullname`	`string`	Select a value from the drop down menu.
Branch Name	`branchName`	`string`	The name of the new branch that will be created
Source Branch	`branchSha`	`string`	Select a value from the drop down menu.

Action 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:
