Setcom integrates using Auto-post callback
Use this integration if you are using Auto-post for another purpose, such assome kind of digital delivery or membership registration etc.

To integrate with Setcom, you need Setcom plugin which is distributed with PAP by default.

1.

Configure plugin

First you must activate Setcom plugin in PAP->Startmenu->Plugins. After plugin it's activated you must configure it.Click Configure button. Youmust set your Merchant username, password which you are using to loginto your merchant panel. Merchant identifier is located in your Setcommerchant panel top menu->My account->Overview tab. Leave custom value separator blank.

2.

SetUp your Setcom settings

Login to your Setcom merchant panel. In top menu->Profile->Selling Preferences select Website Payment Preferences. Make sure that Auto-post is set to on and that Auto-post URL is set to http://URL_TO_PostAffiliatePro/plugins/Setcom/setcom.php.
Do not forget save your settings.

3.

Update Buttons

Now add the following code into EVERY Setcom (Buy now, Add to cart and/or Checkout) button form

<input type="hidden" name="MerchCustom" value="" id="pap_dx8vc2s5">

For example:

<form action="https://www.setcom.com/secure/index.cfm" method="post">
  <input type="hidden" name="buttonaction" value="buynow">
  <input type="hidden" name="merchantidentifier" value="12345678920">
  <input type="hidden" name="liddesc" value="auticko">
  <input type="hidden" name="lidsku" value="a123">
  <input type="hidden" name="lidprice" value="150.00">
  <input type="hidden" name="lidqty" value="1">
  <input type="hidden" name="CurrencyAlphaCode" value="ZAR">
  <input type="hidden" name="LIDExpiry" value="1">
  <input type="hidden" name="ShippingRequired" value="0">
  <input type="hidden" name="IsVoucher" value="0">
  <input type="hidden" name="Option1Name" value="custom">
  <input type="hidden" name="Option1Value" value="oldCustom">
  <input type="hidden" name="MerchCustom" value="" id="pap_dx8vc2s5">
  <input type="image" src="https://www.setcom.com/www/graphics/cartbuttons/bn6.gif">
</form>

After this form you must insert:
<script id="pap_x2s6df8d" src="http://URL_TO_PostAffiliatePro/scripts/notifysale.php" type="text/javascript">
</script>

4.

Integration with your script

Now the Auto-post callback is pointed to your script. This callback has to beforwarded also to PAP paypal.php script, which url is http://URL_TO_PostAffiliatePro/plugins/Setcom/setcom.php.In case, your Setcom processing script is in PHP, you can use followingcode to accomplish that. You can place it at the beginning of yourprocessing file.

/* PAP integration */
 $ch = curl_init();
 curl_setopt($ch, CURLOPT_URL, "http://URL_TO_PostAffiliatePro/plugins/Setcom/setcom.php");
 curl_setopt($ch, CURLOPT_POST, 1);
 curl_setopt($ch, CURLOPT_POSTFIELDS, $_POST);
 curl_exec($ch);
/* end of PAP integration */

This will ensure that whole Auto-post callback will be forwarded without affecting your original script
