Enhanced Match is an optional addition to your Pinterest tag that matches conversion data with the person responsible for the conversion. Enhanced Match sends hashed email addresses to Pinterest to match site events when there’s no Pinterest cookie present. Enhanced Match also lets you track cross-device checkouts, which cannot be done otherwise. As a result, you can accurately see conversions reported in Ads Manager.
Replace YOUR_TAG_ID and EMAIL_ADDRESS with your specific information.
You have to format and hash <email_address> using the SHA-256, SHA-1 or MD5 algorithm. <email_address> needs to be lowercase and have all spaces removed.
The formatted and hashed <email_address> has to be added to every Pinterest tag <img> tag URL on your website using the &pd[em]=<hashed_email_address> parameter. This parameter has to be added to both the base code and the event code <img> tags.
<noscript> <img height="1" width="1" style="display:none;" alt="" src="https://ct.pinterest.com/v3/?tid=<YOUR_TAG_ID>&event=<EVENT_NAME>&pd[em]=<hashed_email_address>&noscript=1" /> </noscript>
Replace YOUR_TAG_ID, EVENT_NAME and hashed_email_address with corresponding values or variables on your website.
Pinterest also uses the secure HTTPS connection protocol standard to encrypt any data the tag transmits from a browser to our servers.
If a partner is using the <img> portion of our tag, then they will need to hash the <email_address> prior to passing it to the tag.
Our <img> tag should not be used with an un-hashed <email_address>, but we will not use or store un-hashed values sent through an <img> tag.
If you use our <img> tag, you will need to hash the <email_address> value using SHA-256, SHA-1 or MD5 before passing it to the tag.
Once the tag transmits <email_address> to the Pinterest server, Pinterest checks to see if it’s associated with an existing Pinterest account for the purpose of matching.
We delete the <email_address> value after we complete the matching process.
A matched hashed email address will only be used to match conversions to Pinterest activity.
