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
Rejoiner	`rejoiner`	`app`	This component uses the Rejoiner app.
	`timer`	`$.interface.timer`
List ID	`listId`	`string`	Select a value from the drop down menu.

Trigger Authentication#

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

OpenAI (ChatGPT) Overview#

OpenAI provides a suite of powerful AI models through its API, enabling developers to integrate advanced natural language processing and generative capabilities into their applications. Here’s an overview of the services offered by OpenAI's API:

Use Python or Node.js code to make fully authenticated API requests with your OpenAI account:
