API - Make Custom Invoice

[designpc]

Hi,

 

I have a website made in PHP/MySQL, it builds up servers, therefore the price of each configuration is always different.

 

So my questions is:

 

Is it possible to create new products (i.e. a custom server config) on demand by the user, so that I can use the payment gateway process in WHMCS?

 

I think this would be done using the API, however im very new to API...

 

Thanks in advanced

You can create invoices for a user via the API. The instructions for this can be viewed in our online manual here: http://v3manual.whmcs.com/?id=137

Thanks Matt for the reply.

 

I did read the manual pages on API, however, I have never used API in anything before. So if you could give me a few pointers that would be great,

 

So just say I have the following variables;

<?php

$total_cost = 100;
$item_desc = "Custom Build";

$client_first = "Joe";
$client_last = "Bloggs";
$client_email = "j.bloggs@domain.com";

?>

 

I am just a bit unsure how to get the $query_string bit to communicate with WHMCS?

 

Thanks again.

Hi,

 

Please see this manual article on how to connect to the API. It should show you how it has to be done.

designpc, Re the API -- there's a whole new section in the manual, only a few entries, but you should read the lot!

Hi,

 

I have read all the manual's info on API, but like I said, I've never used any API before. Ideally, it would be helpful if I could look at an example.

 

You see im unsure what to do with the query_string, I can make the query_string up fine with all the info passed from the variables I already have, its just getting that info into WHMCS...

 

Do I need to make a link do say domain.com/whmcs/order.php?[the query_string] ??

 

Thats the bit im stuck on.

 

Thanks again

[Matt]

The link above that I gave you explains how to use it. You need to request the file includes/api.php

Hi Matt,

 

I have read the link you gave me and all the sections under "API" in the manual, and I think I understand it all.

 

The problem is, do I have to send query_string through a form or some other means, a working example if anyone has one would be great.

 

Also does it matter if I am trying to connect from another server?

 

Thanks

[brianoz]

Designpc, there actually IS a working example there - you send the query string using curl, exactly as in the example given in the API section in the manual... it couldn't be clearer than being right there in front of you on the page.

Doesn't matter which server you connect from in theory, although in practice WHMCS licencing issues may cause problems depending on what code you pull in.

[designpc]

LOL,

 

I think I might be looking to much into the whole process here...

 

This is what I have so far, is this correct?

 

<?php

$url = "http://My_domain_here.com/whmcs/includes/api.php"; # URL to WHMCS API file goes here

$username = "my_user_here"; # Admin username goes here
$password = "my_pass_here"; # Admin password goes here


$query_string = "username=".$username."&password=".md5($password)."&"
$query_string .= "action=addinvoicepayment&invoiceid=15&transid=453685410&amount=40&gateway=paypalinvoices";


$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url );
curl_setopt($ch, CURLOPT_POST, 1 );
curl_setopt($ch, CURLOPT_POSTFIELDS, $query_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$postresult = curl_exec($ch);
if (curl_errno($ch)) {
   echo curl_error($ch);
}
curl_close($ch);

# Check result here...

?>   

 

I called this api.php just to test it, then I run the file, but i get a T_VARIABLE error on line 10?

 

Thanks

[brianoz]

If it has a syntax error it's not correct is it

 

I'm not sure if it's right or not, but run it (after putting back the ';' at end of the first query_string line) and see if it works!

Hi brianoz,

 

I thought the ";" was the error, so I guess the manual should be changed...

 

Right, I have put the ";" back in, ran the script again, and still nothing, I have tried the query_string for creating a new user as well

 

$query_string .= "action=adduser&firstname=Test&lastname=User&email=test@whmcs.com&address1=Demo&city=Test&state=Test&postcode=TT122&country=UK&phonenumber=01234567890&password=temp";

 

and still no user added to WHMCS?

 

Thanks

[Matt]

You may need to open a ticket and request the latest api file.

Just an update to this post.

 

I got the latest api.php file from WHMCS support, and I have the API working great now.

 

Thanks all.
