How to connect OpenAI GPT Assistants and pdfFiller
Create a New Scenario to Connect OpenAI GPT Assistants and pdfFiller
In the workspace, click the “Create New Scenario” button.

Add the First Step
Add the first node – a trigger that will initiate the scenario when it receives the required event. Triggers can be scheduled, called by a OpenAI GPT Assistants, triggered by another scenario, or executed manually (for testing purposes). In most cases, OpenAI GPT Assistants or pdfFiller will be your first step. To do this, click "Choose an app," find OpenAI GPT Assistants or pdfFiller, and select the appropriate trigger to start the scenario.

Add the OpenAI GPT Assistants Node
Select the OpenAI GPT Assistants node from the app selection panel on the right.
