## What it does

The skill walks your agent through the Content API. A template gets a `ContentSid` like `HX...`, and sending happens with `content_sid` plus `content_variables`. Supported types include `twilio/text`, `twilio/media`, `twilio/quick-reply`, `twilio/call-to-action`, `twilio/list-picker`, `twilio/card` and `twilio/carousel`, each tied to its own set of channels.

Ready-made Python and Node.js calls cover template creation, sending, approval submission, status checks, listing and deletion. Variables run sequentially — `{{1}}`, `{{2}}` — with no gaps, up to 100 per template, and the non-variable to variable ratio has to be at least `(2x + 1) : x`.

You need a Twilio account, the `TWILIO_ACCOUNT_SID` and `TWILIO_AUTH_TOKEN` environment variables, and the SDK: `pip install twilio` or `npm install twilio`. WhatsApp templates also need an active sender. One thing to plan around: without Meta approval a WhatsApp template cannot be sent outside the 24-hour service window, and a rejected template cannot be resubmitted under the same name — pick a new one.

npx skills add openai/plugins --skill twilio-content-template-builder -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/twilio-content-template-builder/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/twilio-content-template-builder/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/twilio-content-template-builder/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

```bash
gemini skills install https://github.com/openai/plugins --path plugins/twilio-developer-kit/skills/twilio-content-template-builder
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/twilio-content-template-builder/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/openai/plugins/tree/HEAD/plugins/twilio-developer-kit/skills/twilio-content-template-builder/SKILL.md

## When to use it
- create a message template with variables through the Content API
- send a WhatsApp message by `ContentSid`
- submit a template for Meta approval and track its status
- pick the right content type for a given channel
- add SMS fallback text to an RCS template

## Example prompts
- Create an appointment-reminder template with variables {{1}}, {{2}} and {{3}}, then show me the ContentSid
- Send that template to whatsapp:+15558675310 with Sarah as the name
- Submit the template for approval in the UTILITY category and check the status

description: >
  Create, manage, and send message templates using Twilio's Content API.
  Covers template creation for WhatsApp, SMS, RCS, and MMS; variable usage;
  WhatsApp Meta approval; and sending templates via ContentSid. Use this skill
  when building structured messages that require pre-approval or consistent
  formatting across channels.
---

## Overview

The Content API creates channel-agnostic templates identified by a `ContentSid` (`HX...`). WhatsApp templates must be approved by Meta before use outside the 24-hour service window.

---

## Prerequisites

- Twilio account — New to Twilio? See `twilio-account-setup`
- For WhatsApp templates: active WhatsApp sender
  — See `twilio-whatsapp-send-message` (sandbox) or `twilio-whatsapp-manage-senders` (production)
- Environment variables:
  - `TWILIO_ACCOUNT_SID`
  - `TWILIO_AUTH_TOKEN`
  — See `twilio-iam-auth-setup` for credential setup and best practices
- SDK: `pip install twilio` / `npm install twilio`

---

## Quickstart

**Step 1 — Create a template via Console** (simplest)

Console > Messaging > Content Template Builder > Create new. Use `{{1}}`, `{{2}}` for variables. Save to get a `ContentSid`.

**Step 2 — Send the template**

**Python**
```python
import os
from twilio.rest import Client

client = Client(os.environ["TWILIO_ACCOUNT_SID"], os.environ["TWILIO_AUTH_TOKEN"])

message = client.messages.create(
    from_="whatsapp:+14155238886",
    to="whatsapp:+15558675310",
    content_sid="HXxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    content_variables='{"1": "Sarah", "2": "March 28", "3": "10:00 AM"}'
)
print(message.sid)
```

**Node.js**
```node
const twilio = require("twilio");
const client = twilio(process.env.TWILIO_ACCOUNT_SID, process.env.TWILIO_AUTH_TOKEN);

const message = await client.messages.create({
    from: "whatsapp:+14155238886",
    to: "whatsapp:+15558675310",
    contentSid: "HXxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    contentVariables: JSON.stringify({ "1": "Sarah", "2": "March 28", "3": "10:00 AM" }),
});
```

## Key Patterns

### Create a Template via API

**Python**
```python
template = client.content.v1.contents.create(
    friendly_name="appointment-reminder",
    language="en",
    types={
        "twilio/text": {
            "body": "Hi {{1}}, your appointment is on {{2}} at {{3}}. Reply YES to confirm."
        }
    }
)
print(template.sid)  # HXxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
```

**Node.js**
```node
const template = await client.content.v1.contents.create({
    friendlyName: "appointment-reminder",
    language: "en",
    types: {
        "twilio/text": {
            body: "Hi {{1}}, your appointment is on {{2}} at {{3}}. Reply YES to confirm.",
        },
    },
});
````
