New Campaigns APIs and Assistant Improvements

Campaign API Endpoints

Create, retrieve, and manage campaigns using the new /campaign endpoints. Build automated call campaigns with specified customers and schedules.

General Availability: Assistant.modelOutputInMessagesEnabled is now generally available without beta limitations. You can decide whether to use the model’s output in conversation history instead of the assistant’s speech transcription.

Simplified Assistant Property Structure: Properties like serverMessages, clientMessages, and serverUrl have been moved under Assistant.monitorPlan. This reorganization simplifies how you configure monitoring for your assistants.
Node-Level Overrides for Model and Voice: In Conversation Node, properties like model, voice, and transcriber now explicitly override the workflow’s settings. This allows you to customize these settings for individual nodes within a workflow for greater control.
Enhanced Credential Configuration in Assistants: Assistants now support credentials and credentialIds, similar to workflows. This allows you to specify dynamic credentials specifically for assistant calls, enhancing security and flexibility.
New Models Available in ConversationNode: You can now use Google Models and Custom Models in conversation nodes. This expands the range of language models that can be integrated into conversation nodes.
