Hooks for API integration?

[stefanogaruti]

I'm planning to develop a (sort of) plugin to integrate S2Member with ZOHO invoice (https://invoice.zoho.com/) via ZOHO API (http://www.zoho.com/invoice/api/index.html).

As first step I would like to create a new "Customer" in ZOHO Invoice any time a new user register on S2Member. Later I'll add the possibility to create a new Invoice any time a user make a payment.

I would use the S2Member API/notification fields, but the ZOHO's API requires this actions to be POST and not GET.

Can you please point me to the equivalend action hooks for those API/notification events so I can hook in with my code?

Do you know of any other way to do this? And/or any other developer who already has done someting similar

Thank you

Stefano

Hi,

I believe you may be able to use the user_register hook to accomplish this instead of going directly through the s2Member API.

If you look, WordPress will give you the id for the new user, so all you will need to do is get the user data ( includes data from the wp_users and wp_usermeta tables ), and then populate the other fields with s2Member user meta.

Something like this:

Code: Select all

<?php
function get_s2_usermeta ($id)
   {
      //Get the user data <http://codex.wordpress.org/Function_Reference/get_userdata/>
      $user = get_userdata ($id);
      //Usermeta value for s2Member registration IP Address
      $registration_ip = get_user_meta ($id, 'wp_s2member_registration_ip');
      //usermeta value for s2Member Login Counter ( Not useful for this )
      $logins = get_user_meta ($id, 'wp_s2member_login_counter');
   }
add_action ('user_register', 'get_s2_usermeta');
?>

You could use the Notifications API with a script that GETs the notification and then POSTs it to ZOHO. Would that work for you?

Thanks!
Yes Cristian, it would works... but really isn't there an action hook?

An action hook for each of the notification fields/events could allow to plugins developer to extend S2Member with a lot of other application that maybe requires more tha a simple GET url

I found "ws_plugin__s2member_before_new_user_notification". viewtopic.php?f=40&t=13011&src_doc_v=111105#src_doc_line_175

But I'll email Jason asking him about it for any tips that could help you.

Thanks for the excellent questions.

As first step I would like to create a new "Customer" in ZOHO Invoice any time a new user register on S2Member. Later I'll add the possibility to create a new Invoice any time a user make a payment.

I would use the S2Member API/notification fields, but the ZOHO's API requires this actions to be POST and not GET.

I would try to stick with s2Member's API Notifications on this. You will save yourself some time and everything is better documented for this approach. Trying to use lots of Hooks in this regard can become too complex, and is subject to change slightly in future releases of s2Member.

For instance, you might use s2Member's Signup and Payment Notifications for your needs in this case. For further details, please check your Dashboard here: s2Member -> API Notifications.

The difference between GET/POST is easy to overcome. If your 3rd party service needs to receive POST data instead of GET, connect s2Member's API Notifications to a proxy script of your own, which receives the GET vars, and POSTs them to your 3rd party service in the way it needs them.

Code: Select all

<?php
$_3rd_party_service = /* Change this. */ "http://3rd-party-service.com/api";
$response = curlpsr ($_3rd_party_service, http_build_query (trim_deep (stripslashes_deep ($_GET))));
/*

/*
Recursive function that trims deeply.
*/
function trim_deep ($value = FALSE)
    {
        return is_array ($value) ? array_map ("trim_deep", $value) : trim ((string)$value);
    }
/*
Recursive function that strips slashes deeply.
*/
function stripslashes_deep ($value = FALSE)
    {
        return is_array ($value) ? array_map ("stripslashes_deep", $value) : stripslashes ((string)$value);
    }
/*
cURL operation for posting data and reading response.
*/
function curlpsr ($url = FALSE, $postvars = array (), $max_con_secs = 20, $max_stream_secs = 20, $headers = array ())
    {
        if (($url = trim ($url)) && ($c = curl_init ()))
            {
                if (is_array ($postvars)) /* Because cURL can't deal with complex arrays. */
                    /* Since cURL can't deal with complex arrays, we force this to a query string. */
                    $postvars = http_build_query ($postvars);
                /**/
                curl_setopt_array ($c, /* Configure options. */
                array (CURLOPT_URL => $url, CURLOPT_POST => true,/**/
                CURLOPT_CONNECTTIMEOUT => $max_con_secs, CURLOPT_TIMEOUT => $max_stream_secs, /* Initial connection & stream seconds. */
                CURLOPT_HEADER => false, CURLOPT_RETURNTRANSFER => true, CURLOPT_HTTPHEADER => $headers, CURLOPT_POSTFIELDS => $postvars,/**/
                CURLOPT_FOLLOWLOCATION => ($follow = (!ini_get ("safe_mode") && !ini_get ("open_basedir"))), CURLOPT_MAXREDIRS => (($follow) ? 5 : 0),/**/
                CURLOPT_ENCODING => "", CURLOPT_VERBOSE => false, CURLOPT_FAILONERROR => true, CURLOPT_FORBID_REUSE => true, CURLOPT_SSL_VERIFYPEER => false));
                /**/
                $o = trim (curl_exec ($c));
                /**/
                curl_close($c);
            }
        /**/
        return (!empty ($o)) ? $o : false;
    }
?>
