The query string parameters in the URL of a Pinterest Tag network request contain data sent to Pinterest from advertiser websites.
HTTP cookies, or web cookies, are small pieces of data that work like receipts for websites you visit while browsing the Internet. Domains create stored information on a person’s browser while the person browses the site. For example, cookies allow websites to keep track of the items in your basket as well as other pieces of information.
You can view these parameters to check whether your tag is working correctly.
We recommend checking the following query string parameters for the Pinterest Tag:
- loc: location URL
- ref: referrer URL
- if: (boolean) whether the tag fired from within an iframe
- sh: screen height
- sw: screen width
- em: hashed email address value
- tm: tag manager that was used, if any
The Pinterest Tag reads the following cookies:
_pinterest_sess is the Pinterest login cookie. It contains user ID(s), authentication token(s) and timestamps. If the person is logged out, authentication tokens are deleted but we leave the cookie present. We use the logged out user ID(s) to optimise the person’s experience and measurement.
_pinterest_ct and _pinterest_ct_rt are identical. They contain a user ID and the timestamp at which the cookie was created.
_derived_epik is placed by the Pinterest Tag when a match is identified and no cookies are present, such as Enhanced Match.
_pin_unauth is a first-party cookie that groups actions for users who cannot be identified by Pinterest.
_pinterest_ct_ua is identical to _pin_unauth, but as a third-party cookie.
_routing_id is a first-party cookie that helps ensure that our website user are being directed to the latest version of Pinterest.com.
The Pinterest Tag creates and accesses cookies in a first-party context on your site domain, providing better visibility of the Pinterest traffic on your site. You can delete first-party cookies at any time.
The cookies are persistent for one year from when you install the tag but can be deleted at any time.
