Heroku Overview#

The Heroku API offers programmatic access to Heroku's cloud platform, enabling developers to automate, extend, and integrate their app's lifecycle events with other services. With Pipedream, you can harness the Heroku API for powerful automation, such as managing apps, dynos, add-ons, and configuring scaling operations. Pipedream's ability to connect with multiple services allows for creating complex workflows, such as syncing your development pipeline with external project management tools or triggering alerts based on app metrics.

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
Heroku	`heroku`	`app`	This component uses the Heroku app.
N/A	`http`	`$.interface.http`	This component uses `$.interface.http` to generate a unique URL when the component is first instantiated. Each request to the URL will trigger the `run()` method of the component.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
App ID	`appId`	`string`	Select a value from the drop down menu.
Entities	`entities`	`string[]`	Select a value from the drop down menu:`{ "value": "api:addon-attachment", "label": "addon-attachment - An add-on has been attached or removed from the app" }{ "value": "api:addon", "label": "addon - An add-on for the app has been newly provisioned or deleted, or its details have been modified" }{ "value": "api:app", "label": "app - The app itself has been provisioned or deleted, or its details have been modified" }{ "value": "api:build", "label": "build - A new build for the app has been initiated or the build’s status has changed since the last notification" }{ "value": "api:collaborator", "label": "collaborator - A collaborator has been added or removed from the app, or an existing collaborator’s details have been modified" }{ "value": "api:domain", "label": "domain - Custom domain details have been added or removed from the app" }{ "value": "api:dyno", "label": "dyno - A new dyno has begun running for the app" }{ "value": "api:formation", "label": "formation - The dyno formation for a particular process type has been modified" }{ "value": "api:release", "label": "release - A new release for the app has been initiated or the release’s status has changed since the last notification" }{ "value": "api:sni-endpoint", "label": "sni-endpoint - An SNI endpoint has been specified or removed for the app, or the existing SNI endpoint’s details have been modified" }`

Trigger Authentication#

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

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