Pinterest Ads conversion tracking for cannabis dispensaries

Specific to Pinterest × Cannabis dispensaries

Pinterest and dispensaries: no ads, and no epik on organic Pins

Pinterest's advertising guidelines prohibit drugs and drug paraphernalia, cannabis included, so a dispensary has no Pinterest checkout event and no epik click identifier to capture. If you pin product or lifestyle content organically, tag each Pin's link with UTM parameters and attribute completed POS orders to that source.

How Pinterest and cannabis dispensaries actually connect

1. 1

   The conversion in cannabis dispensaries

   The money event is a completed, paid order. What changes here is not the definition but which channels can legally carry an identifier to it at all.

2. 2

   Pinterest Ads needs a click to match

   An event name Pinterest recognizes, an event_id matched to the tag, a timestamp, hashed customer information, and the click identifier where you have it. Read the delivered and matched counts in Pinterest's reporting rather than assuming a 200 response means the event landed usefully.

3. 3

   The identifier: the epik click identifier

   Pinterest appends epik to your landing page URL and the tag stores it in the _epik cookie. It is a single parameter rather than Google's three, which makes capture simpler — but Pinterest traffic skews heavily to iOS and to saved Pins opened weeks after they were first seen, so the identifier frequently arrives on a visit that is nowhere near the conversion. Persist it server-side the moment you see it.

4. 4

   Where it gets sent from

   The POS — completed and paid orders by date, split direct versus marketplace.

5. 5

   Deduplication and window

   Same shape as Meta: the browser tag and the Conversions API event must carry the same event_id for the same conversion, and the event name must match too. Send both without pairing them and every conversion counts twice. This is worth testing deliberately, because Pinterest volumes are often low enough that a doubling looks like a good week rather than a bug. Pinterest's attribution windows are configurable per campaign and separate the click path from the engagement and view paths, which is unusual. Confirm which window your reporting is set to before comparing anything, and verify the accepted event-freshness limit for server events against Pinterest's current documentation.
