# SMS Service

> Add SMS sending capabilities to your app using Alibaba Cloud or Tencent Cloud SMS.

## What It Is

SMS Service is a plugin that adds SMS sending capabilities to apps you build. It supports **Alibaba Cloud** and **Tencent Cloud** as SMS providers.

The plugin is enabled per project. After configuring your provider credentials, the AI assistant reads your SMS templates and helps you match them to the right scenarios.

***

## Where to Find It

1. Open any project.
2. Switch to the **Build** tab.
3. Open **Skill Library** from the left navigation.
4. Find **SMS Service** in the plugin cards.

***

## Enable

Any of the following enables it:

* Hover the plugin card and click **Use**.
* Open the plugin detail page and click **Use** in the header.
* Confirm the plugin enablement card when the AI assistant suggests it in chat.

After enabling, configure your SMS provider credentials on the plugin detail page.

***

## Configure

Open the plugin detail page after enabling. Fill in the four required fields:

* **Provider**: select `aliyun` or `tencent`. Only these two are supported.
* **API Key / AccessKeyId**: your SMS provider API key or access key ID.
* **API Secret / AccessKeySecret**: your SMS provider API secret or access key secret.
* **Sign Name**: your approved SMS sign name from the provider console.

Click **Save configuration** to save. After saving, the AI assistant fetches your SMS template list from the provider API and confirms which template to use for each scenario in a conversation with you.

### Rules before sending

* Verification-code templates cannot be reused for notification or marketing messages.
