Passing constant variable using CloudPagesURL

Question

I am using CloudPageURL to pass a couple of DE attributes along with a Constant variable and have them populate in a Cloudpage Smartcapture field that is hidden.

Below is my code in the email

<a href="%%=CloudPagesURL(3036,'id',[Id],'accountid',[ICP External],'nps', "0")=%%" target="_blank"><img class="survey-table" data-assetid="260729" src="button.png"></a>

[Id] & [ICP External] are DE attributes whereas 'nps' has a constant value of 0 that i want to pass.

Below is my code in the Cloud page

%%[
var @id, @nps, @accountid
set @id = RequestParameter('id')
set @nps = RequestParameter('nps')
set @accountid = RequestParameter('accountid')
]%%

<input name="Id" type="hidden" value="%%=v(@id)=%%">
<input name="accountid" type="hidden" value="%%=v(@accountid)=%%">
<input name="nps_rating" type="hidden" value="%%=v(@nps)=%%">

It works when i only pass DE attributes but says 'Bad request' if i include the 'nps' variable. What am i doing wrong here. Is it possible to pass a constant variable using CloudPagesURL along with attributes from the sendable DE?

Your help here is appreciated.

Answer 1

Try this - in your email, set all parameters as variables:

%%[
set @id = [Id]
set @accountid = [ICP External]
set @nps = "0"
]%%

And pass the variables in your CloudPagesURL function:

CloudPagesURL(3036,'id',@id,'accountid',@accountid,'nps',@nps)

Not sure why you are passing the nps value since it’s hardcoded to be 0 - if it’s not going to change, then I would just skip it and hardcode it inside the CloudPage. In that case do just:

CloudPagesURL(3036,'id',@id,'accountid',@accountid)

If you’re using WAC/Parameter Management to add additional parameters to your links at send time, you will have to wrap your CloudPagesURL function in a RedirectTo function:

RedirectTo(CloudPagesURL(3036,'id',@id,'accountid',@accountid))

EDIT

Turns out passing the value of 0 is a problem, so try to avoid it if possible.

Answer 2

Try this

%%[
  
  Set @LPID = 3036
  var @id, @accountid
  
  set @id = concat('id=', [id])
  set @accountid = concat('&accountid=', [ICP External])

  Set @UTMParameters = concat(@id, @accountid, '&nps=0')
]%%

<a href="%%=RedirectTo(Concat(CloudPagesURL(@LPID), @UTMParameters ))=%%" target="_blank"><img class="survey-table" data-assetid="260729" src="button.png"></a>
