A Webhook node calls any outside API mid conversation with any of the five standard HTTP methods, carries authorization in custom headers, sends JSON and XML bodies as well as HTML, plain text or form content built from conversation parameters, and maps fields from the response into parameters the flow uses next.

Success and failure paths branch on status codes or code classes, requests can run asynchronously, and timeouts run from 10 to 25 seconds. Salesforce action nodes get records through SOQL and create or update records on any object the team names, after a connection set up from the API dashboard. An email connector and custom code nodes round out the set, so an agent can update a booking, open a case or check an order while the customer waits.

Agents run as flows of nodes on a drag and drop canvas, where collect input, condition, webhook, Salesforce, Q&A, routing and set parameter nodes chain into multistep business logic, and inbound and outbound events start different parts of the same agent. The agentic NLU engine adds a hub and branch pattern.

An agentic classification node uses a language model to match the caller to an intent, an agentic capture node gathers that intent's details, and the agent picks its next move, such as asking a question or calling an API, sending the caller back to the hub when the intent changes. That engine is gated, English only and for voice agents, so most flows run on intent based routing designed in advance.

Knowledge AI answers from the customer's own content through retrieval over Google Gemini models. Sources come in as PDF, text or HTML files, single web pages or public cloud storage links, are grouped into indexes shared by every agent under the same API key, and are queried through a Q&A node in the flow.

Replacing a source in an index updates live agents without republishing them, and an index tester shows which source produced an answer. Each master account includes a 100MB knowledge base, files run up to 10MB for PDF and 5MB for HTML or text, and tables and text inside images are not indexed.

Live agent routing hands WhatsApp, SMS and web chat conversations to people, with WebSocket connections for HTTP agents, and voice agents route calls onward. Agentic nodes ship with built in safety guardrails and detect frustration from repeated failures, escalating on their own, and a global intent such as talk to an agent can be set up. Edits stay in an editor version until someone publishes, and earlier versions can be restored. Nothing lets a person approve an action or a reply before the agent sends it.

AI Studio holds ISO 27001 and HIPAA compliance, with SOC 2 Type II pending alongside PCI DSS compliance and a CSA listing, while Vonage's core SMS and voice APIs already hold ISO 27001 and a SOC 2 Type II report. Account owners invite team members to the API dashboard and assign each one permissions by checkbox, changing them later from a manage column, and sources and agents are scoped to API keys and sub accounts. Vonage's listings for AI Studio vary between its certification table and its product section, and they say nothing of single sign on for the dashboard.

The call log shows every session with its transcript, the parameters collected underneath it and a flow path marking each node as success, warning or error, plus an overall status such as completed, no answer or failed. A tags report counts sessions by tag, and the Vonage Contact Center dashboard tracks resolved, escalated and abandoned sessions.

An audit log records each change to an agent, its type such as an edit, a publication or a deletion, the time and the user who made it. Transcripts are kept for 90 days and telephony recordings for 30, and an Insights API exposes transcripts and recordings to other systems.

User parameters carry what an agent collects from one conversation to the next. Values are saved automatically against the caller's phone number, reused across sessions and across voice, WhatsApp and SMS, and shared by every agent under the same API key, so a collect input node can skip a question already answered. Only the last value for each parameter is kept, and HTTP agents are not covered. Vonage gives no retention period for these values and no way to erase one caller's stored history. Agentic nodes carry their own memory settings inside a single call.

Each agent is created in either the US or Europe, and the choice carries through to its API host, with separate US and EU studio endpoints, so a team can keep European conversations on European infrastructure agent by agent. Knowledge AI indexes sit under the same API key as the agents that query them. AI Studio runs as a hosted service only, with no private cloud or on premises edition.

New agents can start from ready made templates, each a working agent for one job. They cover taking a message after hours, updating a customer's details, a post call survey, FAQs, package tracking, caller identification and verification, general customer service, hotel bookings and appointment management. A team picks one when creating the agent and adjusts the flow afterward, adding its own webhook calls, Salesforce steps or Knowledge AI answers where the template stops.

Four agent types cover telephony, WhatsApp, SMS and HTTP for web and app chat, and each agent listens for inbound or outbound events, with more events added later. Outbound voice, WhatsApp and SMS sessions start at one per second by default, with three or five a second on approval, and voice agents can call SIP endpoints. HTTP agents start through an init call and advance with a step call carrying the user's text and parameters, so any web or mobile front end can drive the same agent. Phone numbers bought on the Vonage dashboard link to an agent at publish time.

Knowledge AI runs on Google Gemini models picked by Vonage, and the agentic NLU engine uses language models it does not name. The older Generative AI node let a team connect its own OpenAI key and organization for GPT 3.5 replies, and Vonage is phasing that node out in favor of Knowledge AI. Intent recognition runs on Vonage's own traditional or hybrid NLU engines.

HTTP agents expose a finished agent as an API. An init call with the account API key and agent ID opens a session and returns a session token, and step calls send the user's input and parameters and return the agent's messages and session status, on regional US and EU hosts. An Insights API returns conversation data under its own authentication, and Vonage's Voice, Messages, SMS and Verify APIs, SDKs and dashboard sit around the studio.

The tester runs a live conversation by chat or by an outbound call to the builder's phone, with parameter values set in advance to steer the flow, a no input option, a jump from any message to its node on the canvas and a flag on each webhook call showing whether it succeeded, with the raw conversation JSON for failures. Knowledge AI indexes can be tested on their own, showing which source answered. These are hands on checks. Saved test cases, pass or fail results and runs across many conversations at once are not part of the product.

Agents reach other systems through webhook, Salesforce, email and custom code nodes, and Knowledge AI reads a single web page when it is added as a source. No hosted browser, remote desktop or screen control is part of AI Studio.
