Save and Activate the Scenario
After configuring CryptoPro, ZeroBounce, 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 ZeroBounce integration works as expected. Depending on your setup, data should flow between CryptoPro and ZeroBounce (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
Most powerful ways to connect CryptoPro and ZeroBounce
ZeroBounce + CryptoPro + Google Sheets: When a new row is added to Google Sheets, the email address in that row is validated using ZeroBounce. Then, CryptoPro signs a file containing the validation result, and the signature is added as a comment to the same Google Sheets row.
HubSpot + ZeroBounce + CryptoPro: When a new form is submitted in HubSpot, the submitted email address is validated using ZeroBounce. The validation result is then digitally signed using CryptoPro, and finally, the contact in HubSpot is updated with the signed validation information.
