Genesys Cloud enables triggered updates through the Salesforce External Contact Sync integration by configuring webhook URLs to synchronize contact data between systems. The setup process requires a pre-configured Salesforce External Contact Sync integration and involves obtaining the webhook URL from Genesys Cloud via Menu > IT and Integrations > Integrations, then copying it from the integration's Edit Integration settings. Users must then complete platform-specific configuration steps in either Salesforce Classic or Salesforce Lightning by navigating to Custom Settings, creating a new entry named "default," and pasting the webhook URL into the designated field before saving. Both Salesforce interfaces follow identical configuration logic but differ in navigation paths—Classic uses Build > Develop > Custom Settings while Lightning uses Platform Tools > Custom Code > Custom Settings. This integration facilitates real-time contact synchronization between Genesys Cloud and Salesforce environments.
