manage_interaction_participants
Add, remove, or list participants in a Flex interaction channel. Add requires the native Type and MediaProperties payload, with optional RoutingProperties. Closing a participant changes its task/reservation state and retains history; it does not delete the interaction.
manage_task_queues
Create, read, update, delete, or list task queues in a TaskRouter workspace. Task queues hold tasks waiting to be assigned to workers. Each queue has a target worker expression that determines which workers are eligible to receive tasks from it.
create_interaction
Create a new customer interaction in Twilio Flex. Use this to initiate inbound or outbound conversations across supported messaging channels. Specify the channel type, routing configuration, and participant details.
manage_interaction_channel
Get details or update the status of a channel within a Flex interaction. Use this to close a channel, fetch channel status, or list all channels for an interaction.
manage_workflows
Create, read, update, delete, or list workflows in a TaskRouter workspace. Workflows define the routing rules that determine how tasks are assigned to workers based on task attributes and queue configurations.
manage_flex_flows
Legacy Programmable Chat in Flex reached end of life on June 1, 2026 and may stop working. Migrate to Flex Conversations and Interactions. This tool preserves documented legacy CRUD. Create, read, update, delete, or list Flex Flows. A Flex Flow defines how incoming messages on a given channel (SMS, WhatsApp, web chat, etc.) are routed into the Flex contact center. It links a messaging channel to Flex and specifies the integration type (Studio flow, external webhook, or direct task creation).
manage_workers
Create, read, update, delete, or list workers (agents) in a TaskRouter workspace. Workers represent the agents who handle tasks in your Flex contact center. You can update their attributes and current activity. Activity availability determines whether they can accept tasks.
manage_tasks
Create, read, update, cancel, or list tasks in a TaskRouter workspace. Tasks represent units of work that need to be routed to workers. You can create new tasks, update their attributes or priority, complete or cancel them, and filter the task list by status or assignment.
manage_conversations
Create, read, update, delete, or list Twilio Conversations. Conversations are the container for multi-party messaging across channels. Use this to set up new conversation threads, update their state, or retrieve conversation details.
manage_conversation_participants
Add, remove, update, or list participants in a Twilio Conversation. Participants can be chat-based (identity) or SMS/WhatsApp-based (phone number). Use this to manage who is part of a conversation.
manage_studio_flows
List, get, or trigger Studio Flow executions. Studio Flows are visual communication workflows for IVR, chatbot logic, and routing. Use this to view available flows, trigger outbound flow executions, or check execution history.
manage_activities
Create, read, update, delete, or list activities in a TaskRouter workspace. Activities describe what workers are doing (e.g., "Available", "Break", "Offline") and whether they are eligible to receive new task assignments.
get_workspace_statistics
Retrieve real-time and cumulative statistics for a TaskRouter workspace. Returns metrics like total tasks, tasks by status, average wait time, available workers, and activity-level breakdowns. Optionally fetch per-queue or per-worker statistics.
send_conversation_message
Send a message in a Twilio Conversation. Supports text messages and can optionally specify the author identity. Use this to programmatically send messages within an active conversation thread.
list_conversation_messages
List messages in a Twilio Conversation. Returns the message history for a given conversation, including author, body, and timestamps. Use order parameter to sort ascending or descending.
get_flex_configuration
Retrieve the current Flex instance configuration. Returns UI settings, enabled channels, account SID, runtime domain, and other configuration properties that control the appearance and behavior of your Flex instance.
list_workspaces
Discover authorized TaskRouter workspaces and their native SIDs before managing workers, queues, tasks, workflows or statistics.
get_interaction
Read one exact Flex interaction and its native channel/routing details after asynchronous acceptance. Use manage_interaction_channel to inspect setup or failure status; acceptance alone does not establish successful delivery or routing.
