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

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

Save and Activate the Scenario
After configuring Captions, CryptoPro, 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 Captions and CryptoPro integration works as expected. Depending on your setup, data should flow between Captions and CryptoPro (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
Most powerful ways to connect Captions and CryptoPro
Captions + CryptoPro + Google Drive: When a video caption file is created or modified, it's automatically encrypted using CryptoPro, then uploaded to a designated folder in Google Drive for secure storage and compliance.
CryptoPro + Captions + Slack: When a file is signed by CryptoPro, indicating it has been decrypted, the system checks for related video captions and sends a notification via Slack to alert the team that sensitive video captions are ready for review.
