The Fuse API provides programmatic integration points for the following Plum Fuse features:

• Queue Call: Queues a single outbound call.
• Bulk Queue Calls: Queues outbound calls in batches from a CSV of contacts.
• Outbound Call Status: Returns the call details for a specific outbound call.
• Cancel Calls: Schedules all pending outbound calls to be canceled.
• Fetch Calls: Gets a filtered and paged list of calls on your account.
• Fetch Call Log: Gets a filtered and paged list of calls on your account.
• Fetch All Call Logs: Gets all calls with details within a given timeframe.

The base URL for all API requests is:

https://fuse.plumvoice.com/api

All API requests authenticate using HTTP Basic Authentication. Use the same email address you use to log into your Fuse account for the username value. Your Developer Key, located in your Account Settings, functions as your password.

Most likely, users will be able to use built-in HTTP Basic Authentication, depending on the HTTP libraries available in the programming language they opt to use.

If the desired programming language does not have HTTP Basic Authentication, users can build the header manually by base64 encoding their email address and developer key, concatenated with a colon (email:developer_key), and then prefixing it with 'Basic'.

Manually built HTTP Basic Authentication in this instance should look like the following example:

"Authentication: Basic your_base64_encoded_string_of_email:developerkey"

Any requests made without this header or with invalid credentials return an HTTP 401 Unauthorized error.
The body of the error message provides details about what went wrong with the request.

The API method honors the following Accept header values. These determine the Content-Type and the representation for the response:

• application/json
• application/xml

Specifying an Accept header other than these values returns a Content-Type of 'application/json' by default.

The Fuse API utilizes the application_id and deployment_id values in many areas.

To locate these values for a specific deployment, navigate to the Outbound Interface.
The “Outbound API Values” are displayed at the top of the page. These include the application_id and deployment_id for that deployment.

https://fuse.plumvoice.com/api/apps/{application_id}/{deployment_id}/queue

POST

application/x-www-form-urlencoded, application/json

Possible Response Codes:

• 200: success, call successfully queued.
• 400: supplied data improperly formatted or invalid
• 401: authentication headers invalid or the account is inactive
• 403: the user attempting to queue the outbound call does not have appropriate permissions
• 404: deployment not found
• 405: invalid HTTP method supplied (only POST allowed)
• 409: user, deployment, or application previously deleted
• 500: database error

The return structure will contain the following item(s):

Note: The returned 'Link' header provides the URI for checking the status of the most recent outbound call attempt.

This sample PHP code makes a request to queue a new outbound call. This triggers an outbound call that goes out immediately and makes a single attempt to connect:

<?php
// account and application settings
$email = '<your_email_address>';
$developer_key = '<your_developer_key>';
$application_id = '<your_application_id>';
$deployment_id = '<your_deployment_id>';
$phone_number = '<phone_number_to_dial>';

// build the URL and POST parameters
$url = 'https://fuse.plumvoice.com/api/apps/'.$application_id.'/'.$deployment_id.'/queue';
$params = array('phone_number'=>$phone_number);

$ch = curl_init();
curl_setopt($ch, CURLOPT_USERPWD, $email.':'.$developer_key);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($params));
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Accept: application/json", "Content-type: application/x-www-form-urlencoded"));
$result = curl_exec($ch);
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
var_dump($result);
var_dump($http_code);

On success (Note the 'Link' header. It's possible to use this URI to check the status of the outbound call):
