## Installation
```bash
npm install nexmo
```
## Constructor
```js
const Nexmo = require('nexmo');
const nexmo = new Nexmo({
apiKey: API_KEY,
apiSecret: API_SECRET,
applicationId: APP_ID,
privateKey: PRIVATE_KEY_PATH,
signatureSecret: SIGNATURE_SECRET,
signatureMethod: SIGNATURE_METHOD
}, options);
```
* `apiKey` - API Key from Nexmo. If `applicationId` and `privateKey` are present, `apiKey` is optional.
* `apiSecret` - API SECRET from Nexmo. If `applicationId` and `privateKey` are present, `apiSecret` is optional.
* `applicationId` - (optional) The Nexmo Application ID to be used when creating JWTs.
* `privateKey` - (optional) The Private Key to be used when creating JWTs. You can specify the key as any of the following:
* A [Buffer](https://nodejs.org/api/buffer.html#buffer_class_method_buffer_from_string_encoding) containing the file contents.
* A String containing the path to the key file on disk.
* `signatureSecret` - (optional) API singature secret from Nexmo, used for signing SMS message requests
* `signatureMethod` - (optional) singature method matching the one you gave Nexmo, used for signing SMS message requests. Must be one of "md5hash", "md5", "sha1", "sha256", or "sha512"
* `options` - (optional) Additional options for the constructor.
Options are:
```js
{
// If true, log information to the console
debug: true|false,
// append info the the User-Agent sent to Nexmo
// e.g. pass 'my-app' for /nexmo-node/1.0.0/4.2.7/my-app
appendToUserAgent: string,
// Set a custom logger
logger: {
log: function() {level, args...}
info: function() {args...},
warn: function() {args...}
},
// Set a custom timeout for requests to Nexmo in milliseconds. Defaults to the standard for Node http requests, which is 120,000 ms.
timeout: integer,
// Set a custom host for requests instead of api.nexmo.com
apiHost: string,
// Set a custom host for requests instead of rest.nexmo.com
restHost: string
}
```
## Callbacks
All methods expect a `callback` function to be passed in, with a method signature of `(error, response)` where:
* `error` - is an Error object if the API call returns an error, or `null` if the API call was successful.
* `response` - is an Object, with the API response if the API call was successful, or `null` if there was an error.
Example:
```js
callback = (error, response) => {
if (error) {
console.error(error)
}
if (response) {
console.log(response)
}
}
```

## JWT
There are two ways of generating a JWT. You can use the function that exists on the Nexmo definition:
```js
const Nexmo = require('nexmo');
const jwt = Nexmo.generateJwt('path/to/private.key', {application_id: APP_ID});
```
Or via a `Nexmo` instance where your supplied `applicationId` and `privateKey` credentials will be used:
```js
const Nexmo = require('nexmo');
const nexmo = new Nexmo({
apiKey: API_KEY,
apiSecret: API_SECRET,
applicationId: APP_ID,
privateKey: PRIVATE_KEY_PATH,
});
const jwt = nexmo.generateJwt();
```
## Signature
There are two ways of generating a signature hash. Both strip the `sig` parameter if supplied. You can use the function that exists on the Nexmo definition:
```js
const Nexmo = require('nexmo');
const hash = Nexmo.generateSignature(SIGNATURE_METHOD, SIGNATURE_SECRET, params);
```
Or via a `Nexmo` instance where your supplied `signatureSecret` and `signatureMethod`:
```js
const Nexmo = require('nexmo');
const nexmo = new Nexmo({
apiKey: API_KEY,
apiSecret: API_SECRET,
signatureSecret: SIGNATURE_SECRET,
signatureMethod: SIGNATURE_METHOD,
});
const hash = nexmo.generateSignature();
```
`SIGNATURE_METHOD` is the signature method matching the one you gave Nexmo. Must be one of "md5hash", "md5", "sha1", "sha256", or "sha512".
## Voice (Deprecated)
### Send TTS Message
```js
nexmo.voice.sendTTSMessage(,message,options,callback);
```
### Send TTS Prompt With Capture
```js
nexmo.sendTTSPromptWithCapture(,message,, ,options,callback);
```
### Send TTS Prompt With Confirm
```js
nexmo.voice.sendTTSPromptWithConfirm(, message ,,'',,,options,callback);
```
## Testing
Run:
```bash
npm test
```
Or to continually watch and run tests as you change the code:
```bash
npm run-script test-watch
```
## Examples
See [examples/README.md](examples/README.md).
Also, see the [Nexmo Node Quickstarts repo](https://github.com/nexmo-community/nexmo-node-quickstart).
## Creating your own requests
> #### IMPORTANT
> This section uses internal APIs and should not be relied on. We make no guarantees that the interface is stable. Relying on these methods is not recommended for production applications
For endpoints that are not yet implemented, you can use the Nexmo HTTP Client to
make requests with the correct authentication method.
In these examples, we assume that you've created a `nexmo` instance as follows:
```javascript
const nexmo = new Nexmo({
apiKey: 'API_KEY',
apiSecret: 'API_SECRET',
applicationId: 'APPLICATION_ID',
privateKey: './private.key',
});
```
* If your API endpoint is on `api.nexmo.com`, use the `nexmo.options.api` object.
* If your API endpoint is on `rest.nexmo.com`, use the `nexmo.options.rest` object.
Both of these objects expose the following methods:
* `get(path, params, callback, useJwt)` (`params` is the query string to use)
* `post(path, params, callback, useJwt)` (`params` is the POST body to send)
* `postUseQueryString(path, params, callback, useJwt)` (`params` is the query string to use)
* `delete(path, callback, useJwt)`
To make a request to `api.nexmo.com/v1/calls?status=rejected`:
```javascript
nexmo.options.api.get(
"/v1/calls",
{"status": "rejected"},
function(err, data){
console.log(err);
console.log(data);
},
true // Use JWT for authentication
);
```
To make a request to `rest.nexmo.com/sms/json?from=Demo&to=447700900000&text=Testing`:
```javascript
nexmo.options.rest.postUseQueryString(
"/sms/json",
{"from": "Demo", "to": "447700900000", "text": "Testing"},
function(err, data){
console.log(err);
console.log(data);
},
false // Don't use JWT, fall back to API key/secret
);
```
