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.

PostHog Overview#

The PostHog API lets you track events, update user properties, and extract analytics to understand user behavior within your applications. Integrating this API into Pipedream workflows allows you to automate actions based on event data, sync user properties across platforms, and trigger alerts or notifications.

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
PostHog	`posthog`	`app`	This component uses the PostHog app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
	`timer`	`$.interface.timer`
Organization ID	`organizationId`	`string`	Select a value from the drop down menu.
Project ID	`projectId`	`string`	Select a value from the drop down menu.

Trigger Authentication#

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

To retrieve your API Key,

Navigate to your PostHog account and sign in
Click on your name/avatar on the top right
Click the gear next to your name to access “Account settings“
Scroll down to “Personal API Keys”

RSS Overview#

The RSS app allows users to automatically fetch and parse updates from web feeds. This functionality is pivotal for staying abreast of content changes or updates from websites, blogs, and news outlets that offer RSS feeds. With Pipedream, you can harness the RSS API to trigger workflows that enable a broad range of automations, like content aggregation, monitoring for specific keywords, notifications, and data synchronization across platforms.
