Hi, In case it is of interest to anyone, I am building a Woocommerce coupon code generator that is triggered from Mautic by a campaign webhook. The idea is that a campaign triggers a GET-call to Woocommerce, which uses the variables provided in the GET to generate a coupon code. The campaign is of the sort that “If you have not shopped for 6 months, you’ll get this coupon code that gives you free shipping and a little discount” This is as far as i’ve gotten this sunday morning; I registered a shortcode that i placed on an otherwise empty page on the woocommerce installation, because that is the only way i know how. Does anyone have a better suggestion how to call the function via an external GET-call? I have “learned” the PHP i know by hammering the keys like a monkey on a typewriter until i don’t get fatal errors anymore, so please excuse the looks of the code, i’m sure it’s horrible. What is provided by mautic is the parameter “6mwb”, 6 month win-back, for recovering lost customers, and the contact ID. Todays date is generated by Woocommerce and used for the coupon syntax and for calculating validity time. Coupon is generated with a set of parameters for its usage, and then it is flung back by a API cUrl call to the same contact in Mautic to a custom field, it all seems to be working. Questions: Do you see timeout problems happening when i run this function and around 1600 api calls are made? Because i currently have around 800 contacts on the “Not shopped for 6 months”-list, and when i eventually launch this campaign, all those calls will trigger at the same time. I see a timeout setting in Mautics campaign webhook sender, would that help me? Or can i add delay functions to the code? There are still things to do, for example i want to have a similiar process run after 12 months, and i need to figure out a how to let mautic know that the code on the custom field is new. Also, i have never experimented with campaigns with this sort of dynamic content (i want the newsletter to say “Here is your code: 6mw22052912345”) but i’ll cross that bridge when i get to it. // register shortcode add\_shortcode(‘codeCreatorWebhook’, ‘codeCreatorWebhook\_function’); function codeCreatorWebhook\_function() { $couponCodeParams = sanitize\_key($\_GET[‘codetype’]); ////Get from URL, and trust but verify $couponCodeContactID = sanitize\_key($\_GET[‘contactid’]); ////Get contact ID from URL, and trust but verify echo “Debug: Codeinput: $couponCodeParams Contact ID input: $couponCodeContactID ”; if ($couponCodeParams==“6mwb” and (!empty($couponCodeContactID)) ) { //Check that parameter 6mwb, 6-month-winback, is provided and that contact id is not empty $todaysDate = date(“ymd”); //Get todays date to use in coupon code generation $todaysdatesinunix = date(‘U’); //Get todays time in Unix for calculating coupon validity time $aWeekFromNow=$todaysdatesinunix+691200; //Add eight days to todays date //Check if coupon exists if( wc\_get\_coupon\_id\_by\_code( “$couponCodeParams$todaysDate$couponCodeContactID” ) ) { echo ‘Debug: Coupon exists’; } else { echo ‘Debug: Coupon does not exist, keep doing stuff. ’; echo “Debug: Coupon to be generated: $couponCodeParams$todaysDate$couponCodeContactID”; //////////////////////////////////// //Create coupon code $coupon\_code = “$couponCodeParams$todaysDate$couponCodeContactID”; // Coupon to be added $coupon = array( ‘post\_title’ =\> $coupon\_code, ‘post\_content’ =\> ‘’, ‘post\_status’ =\> ‘publish’, ‘post\_author’ =\> 1, ‘post\_type’ =\> ‘shop\_coupon’); //$new\_coupon\_id = wp\_insert\_post( $coupon ); //Actual adding of coupon // Add coupon meta update\_post\_meta( $new\_coupon\_id, ‘discount\_type’, ‘percent’ ); // Type: fixed\_cart, percent, fixed\_product, percent\_product update\_post\_meta( $new\_coupon\_id, ‘coupon\_amount’, ‘10’ ); // Amount update\_post\_meta( $new\_coupon\_id, ‘minimum\_amount’, ‘300’ ); // Minimum amount for coupon validity update\_post\_meta( $new\_coupon\_id, ‘individual\_use’, ‘yes’ ); update\_post\_meta( $new\_coupon\_id, ‘product\_ids’, ‘’ ); update\_post\_meta( $new\_coupon\_id, ‘exclude\_product\_ids’, ‘’ ); update\_post\_meta( $new\_coupon\_id, ‘usage\_limit’, ‘1’ ); update\_post\_meta( $new\_coupon\_id, ‘usage\_limit\_per\_user’, ‘1’ ); update\_post\_meta( $new\_coupon\_id, ‘expiry\_date’, $aWeekFromNow ); update\_post\_meta( $new\_coupon\_id, ‘free\_shipping’, ‘yes’ ); update\_post\_meta( $new\_coupon\_id, ‘exclude\_sale\_items’, ‘yes’ ); //////////////////////////////////// //Call Mautic with the coupon $curl = curl\_init(); curl\_setopt\_array($curl, array( CURLOPT\_URL =\> “[https://MY-MAUTIC-INSTALLATION.COM/api/contacts/$couponCodeContactID/edit](https://MY-MAUTIC-INSTALLATION.COM/api/contacts/%24couponCodeContactID/edit)”, CURLOPT\_RETURNTRANSFER =\> true, CURLOPT\_ENCODING =\> ‘’, CURLOPT\_MAXREDIRS =\> 10, CURLOPT\_TIMEOUT =\> 0, CURLOPT\_FOLLOWLOCATION =\> true, CURLOPT\_HTTP\_VERSION =\> CURL\_HTTP\_VERSION\_1\_1, CURLOPT\_CUSTOMREQUEST =\> ‘PATCH’, CURLOPT\_POSTFIELDS =\> “chwoogeneratedcoupon=$coupon\_code”, CURLOPT\_HTTPHEADER =\> array( ‘Cache-Control: no-cache’, ‘Content-Type: application/x-www-form-urlencoded’, ‘token: MY-TOKEN’, ‘Authorization: Basic MY-LOTS-OF-NUMBERS’ ), )); $response = curl\_exec($curl); curl\_close($curl); //echo $response; } } } Edit: If you see anything utterly horrible, please let me know!
