How to connect CryptoPro and pdfFiller
Create a New Scenario to Connect CryptoPro 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 CryptoPro, triggered by another scenario, or executed manually (for testing purposes). In most cases, CryptoPro or pdfFiller will be your first step. To do this, click "Choose an app," find CryptoPro or pdfFiller, and select the appropriate trigger to start the scenario.

Add the CryptoPro Node
Select the CryptoPro node from the app selection panel on the right.

Save and Activate the Scenario
After configuring CryptoPro, pdfFiller, and any additional nodes, don’t forget to save the scenario and click "Deploy." Activating the scenario ensures it will run automatically whenever the trigger node receives input or a condition is met. By default, all newly created scenarios are deactivated.
Test the Scenario
Run the scenario by clicking “Run once” and triggering an event to check if the CryptoPro and pdfFiller integration works as expected. Depending on your setup, data should flow between CryptoPro and pdfFiller (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
