# Twilio APIs

Twilio provides a suite of REST APIs for programmatic communications and customer engagement, spanning SMS and MMS messaging, voice calls, phone number provisioning, chat and conversations, video, two-factor verification, and contact-center routing. The portfolio also covers phone number lookups, serverless functions, real-time state sync, workflow automation with Studio, event streaming, and regulatory compliance through TrustHub. All APIs share a single account authentication model, letting an agent orchestrate messaging, telephony, and identity workflows across more than 180 countries.

## For AI agents

An agent can send SMS and MMS, place and control voice calls, provision phone numbers, run two-factor verification, manage chat and conversation threads, route contact-center tasks, and look up phone number data across Twilio's APIs. It can also drive video rooms, sync shared state, trigger Studio flows, and read insights and events, all through one Twilio account credential.

## Which API to use

| Need | API | Why |
| --- | --- | --- |
| Send an SMS or place a voice call | twilio | The core REST API sends SMS/MMS, makes voice calls, and manages phone numbers directly. |
| Send a message inside a threaded chat or conversation | twilio_conversations_v1 | Conversations handles multi-party threaded messaging state, unlike the fire-and-forget core messaging endpoints. |
| Real-time group chat channels and members | twilio_chat_v2 | Chat manages channels, members, and roles rather than conversation-level configuration. |
| Advanced messaging configuration and services | twilio_messaging_v1 | Messaging manages messaging services and deactivated-number lists separate from the core send endpoint. |
| Verify a user with a one-time passcode | twilio_verify_v2 | Verify issues and checks 2FA tokens, which the core communications API does not do. |
| Route incoming work to agents | twilio_taskrouter_v1 | TaskRouter distributes tasks across queues and workers, unlike Flex which manages the contact-center surface. |

## Cross-API use cases

### Verified transactional SMS

An agent verifies a user with a one-time passcode and then sends a confirmation SMS to the same number once the code checks out.

Example prompt: Start a Verify check for the user's phone number, confirm the submitted code, then send a confirmation SMS through the core API.

### Routed inbound support call

An agent looks up an inbound caller's number, places or bridges the call, and routes the interaction to the right agent queue.

Example prompt: Take an inbound call via the core voice API and create a TaskRouter task to assign it to an available worker in the correct queue.

### Threaded conversation with live chat fallback

An agent manages a customer conversation thread and provisions real-time chat channels for live support when needed.

Example prompt: Update conversation configuration in Conversations, then create a Chat channel and add the customer and agent as members for live messaging.

### Notification-ready number provisioning

An agent looks up and provisions phone numbers, then configures a messaging service to send notifications from them.

Example prompt: Purchase a phone number via the core API and attach it to a messaging service configured in the Messaging API.

## Why Jentic

- **Setup:** Install your own Jentic One instance, and your agent can find and add any Twilio API from the Jentic directory to your workspace without wiring up each REST endpoint by hand.
- **Permission scoping:** Your own rules on your Jentic One instance decide which Twilio operations and credentials the agent may use, so you can allow verification and lookups while withholding number purchasing or account changes.
- **Credential handling:** Your Twilio Account SID and Auth Token are stored encrypted on your own Jentic One instance rather than being exposed to the agent directly.
- **Discovery method:** The agent discovers Twilio's messaging, voice, verification, and routing APIs through the Jentic API Directory and selects the right one per task from the standardized descriptions.

## FAQ

### Does one Twilio credential work across all of these APIs?

Yes. Every Twilio API in this portfolio authenticates with the same Account SID and Auth Token using HTTP basic authentication, so a single set of credentials covers messaging, voice, verification, video, and the rest.

### Which APIs should an agent use for customer messaging?

Use the core Twilio REST API for one-off SMS and MMS, Conversations for threaded multi-party messaging, Chat for real-time channels with members and roles, and Messaging for configuring messaging services and sender pools.

### Can an agent handle voice calls and contact-center routing?

Yes. The core Twilio API places and controls voice calls, Voice adds call recording and archival operations, and TaskRouter distributes calls and other work items across agent queues, with Flex managing the contact-center surface.

### How does Twilio support identity and verification workflows?

Verify issues and checks one-time passcodes for two-factor authentication, Lookups returns data about a phone number, and TrustHub manages regulatory compliance and branded-calling registration.

### What is not covered by Twilio's APIs?

This portfolio does not handle email delivery, CRM record management, payment processing, or hosted website building. It focuses on programmatic communications, verification, and contact-center primitives.

### Can agents build automated communication flows?

Yes. Studio triggers and manages engagement flows, Serverless runs functions and hosts assets, Sync shares real-time state, and Events streams account activity that an agent can react to.
