This is the Vonage Verify (for version 1) SDK for Node.js for use with [Vonage APIs](https://www.vonage.com/). To use it you will need a Vonage account. Sign up [for free at vonage.com][signup].

Note: This package is only compatible with verify V1.

For full API documentation refer to [developer.vonage.com](https://developer.vonage.com/).

If you are updating from V2 to V3 of the SDK, please check the migration guide found [here](https://github.com/Vonage/vonage-node-sdk/blob/3.x/packages/verify/v2_TO_v3_MIGRATION_GUIDE.md)

## Installation

We recommend using this SDK as part of the overall [`@vonage/server-sdk` package](https://github.com/vonage/vonage-node-sdk). Please see the main package for installation.

You can also use this SDK standalone if you only need access to just the Verify API.

### With NPM

```bash
npm install @vonage/verify
```

### With Yarn

```bash
yarn add @vonage/verify
```

## Usage

### As part of the Vonage Server SDK

If you are using this SDK as part of the Vonage Server SDK, you can access it as the `verify` property off of the client that you instantiate.

```js
const { Vonage } = require('@vonage/server-sdk')

const credentials = {
  apiKey: API_KEY,
  apiSecret: API_SECRET,
}
const options = {}
const vonage = new Vonage(credentials, options)

vonage.verify
  .check(VERIFY_REQUEST_ID, CODE)
  .then((resp) => console.log(resp))
  .catch((err) => console.error(err))
```

### Standalone

The SDK can be used standalone from the main [Vonage Server SDK for Node.js](https://github.com/vonage/vonage-node-sdk) if you only need to use the Verify API. All you need to do is `require('@vonage/verify')`, and use the returned object to create your own client.

```js
const { Auth } = require('@vonage/auth')
const { Verify } = require('@vonage/verify')

const credentials = new Auth({
  apiKey: API_KEY,
  apiSecret: API_SECRET,
})
const options = {}
const verifyClient = new Verify(credentials, options)
```

Where `credentials` is any option from [`@vonage/auth`](https://github.com/Vonage/vonage-node-sdk/blob/3.x/packages/auth/README.md#options), and `options` is any option from [`@vonage/server-client`](https://github.com/Vonage/vonage-node-sdk/blob/3.x/packages/server-client/README.md#options)

## Promises

Most methods that interact with the Vonage API uses Promises. You can either resolve these yourself, or use `await` to wait for a response.

```js
const resp = await vonage.vrify.check(VERIFY_REQUEST_ID, CODE)

vonage.verify
  .check(VERIFY_REQUEST_ID, CODE)
  .then((resp) => console.log(resp))
  .catch((err) => console.error(err))
```

## Testing

Run:

```bash
npm run test
```
