I have created a landing page in Marketing Cloud that interacts with my Salesforce Sales Cloud. This page is meant to be a custom landing page where users can opt out of specific email lists or unsubscribe completely. The code is suppose to take the Subscriber ID (which is always matched with a custom field Contact Casesafe Id (contact_casesafeid__c) and pull through their contact information in Salesforce. However, the first line SET @contactId = _subscriberkey does not pull through the Subscriber Key from the email with the embedded link to this page.
I've tested with changing out _subscriberkey to an existing Contact ID and it worked, but I have no idea how to get the Subscriber ID to be pulled through from the email sent. What could I be doing wrong?
I keep receiving the bottom error: "Sorry, something went wrong (missing subscriber key).
%%[ SET @contactId = _subscriberkey IF NOT EMPTY(@contactId) THEN /* fetch data from Sales Cloud to show in the form */ SET @subscriberRows = RetrieveSalesforceObjects( "Contact", "Id,FirstName,LastName,Email,Inside_the_Ropes__c,Wellness_Check_In__c,Special_Promos__c,HasOptedOutOfEmail", "Id", "=", @contactId ) IF RowCount(@subscriberRows) > 0 THEN SET @row = row(@subscriberRows,1) SET @FirstName = field(@row,"FirstName") SET @LastName = field(@row,"LastName") SET @Email = field(@row,"Email") SET @InsideTheRopes = field(@row,"Inside_the_Ropes__c") SET @WellnessCheckIn = field(@row,"Wellness_Check_In__c") SET @SpecialPromos = field(@row,"Special_Promos__c") SET @HasOptedOutOfEmail = field(@row,"HasOptedOutOfEmail") IF @InsideTheRopes == true THEN SET @InsideTheRopeschk = "checked" ENDIF IF @WellnessCheckIn == true THEN SET @WellnessCheckInchk = "checked" ENDIF IF @SpecialPromos == true THEN SET @SpecialPromoschk = "checked" ENDIF ELSE ]%% Sorry, something went wrong (no records found). %%[ ENDIF ELSE ]%% Sorry, something went wrong (missing subscriber key).
