Hi,

I am not sure how did you end up in using Implicit Authentication with PHP.

RingCentral implicit grant flow is meant for browser based apps only. See this dev guide for more details. That's why only the RingCentral JavaScript SDK supports implicit authentication. Once your app receives the access token, normally you use the token to call RingCentral APIs directly from your Javascript code. But for any reason you wish to pass the access token to your PHP backend, it's up to you to write code to pass the token.

Let me know if you have further questions.

It is a browser based app and we use PHP. It is actually an intranet page we are developing and users must use VPN on their mobile devices to get to the intranet pages. I was hoping someone would have a simple piece of code that could accomplish the passing of an access_token. I have done it with other API's most recently Microsoft Graph. However, that hash in the URL is something I haven't come across before and it is tripping me up.

Thought I'd post this to let the forum I no longer need help and it might help someone else ...

Figured out code with some by googling a little more. In case anyone is interested. Basically a combination of javascript (to extract the fragment of the URL that comes after the hash, and pass it to the php code in the form of a cookie).

I am guessing Javascript is processed after php (client side code after server side code), so on first instance of page load, php does not recognize a cookie from javascript. So I reload the page if the cookie isn't set in PHP (hence If (isset($_COOKIE['url'])) with an else refresh). I coudn't tell you if this is the proper or best way of doing this.

Many ways to do this I assume, but I found once the URL parameters are now in a php variable, I split it by "=" and "&" since the url parameters basically look like:

variable_name=value&variable_name2=value2&variable_name3=value3

Now I have an array comprised of alternating variable names and variable values.

In my case, I want the access_token value which happens to be the 4th item of the array ( $exploded[3]) as a result of the explode function.

Now I can use the $access_token value in a relatively simple curl command that hits the Ringcentral API to get extensions or whatever I want.

My code which works:

<?php

echo "<script>

var hash = window.location.hash.substr(1);

document.cookie = 'url=' + hash;

var result = hash.split('&').reduce(function (result, item) {

var parts = item.split('=');

result[parts[0]] = parts[1];

return result;

}, {});

</script>";

If (isset($_COOKIE['url'])) {

function multiexplode ($delimiters,$string) {

$ready = str_replace($delimiters, $delimiters[0], $string);

$launch = explode($delimiters[0], $ready);

return $launch;

}

$access_token_position = strpos($_COOKIE['url'],"access_token=");

$exploded = multiexplode(array("=","&"),$_COOKIE['url']);

$access_token = $exploded[3];

$url_user_details = "https://platform.devtest.ringcentral.com/restapi/v1.0/account/~/extension?client_id=xxxxxxxxxxxxxxxxxxxxxxx&access_token=$access_token";

$ch_user_details = curl_init();

$request_user_details = array();

curl_setopt($ch_user_details, CURLOPT_RETURNTRANSFER, TRUE);

curl_setopt($ch_user_details, CURLOPT_URL, $url_user_details);

curl_setopt($ch_user_details, CURLOPT_HTTPGET, true);

$request_user_details[] = 'Accept: application/json';

curl_setopt($ch_user_details, CURLOPT_HTTPHEADER, $request_user_details);

$planner_user_details_results = curl_exec($ch_user_details);

curl_close($ch_user_details);

ELSE {

header("Refresh:0");

}
