Parse.ly collect beacons need idsite and url

Not the cdn.parsely.com loader. The pixel server is p1.parsely.com, or p1-irl.parsely.com for EU. idsite is the Site ID. url is a required absolute URL, not a relative path. action=pageview is the page view.

Rules

Codes are stable. A finding in CI, MCP, or the playground lands on the same id.

Field Required What it checks Rule ids Source
idsite required It is the Parse.ly Site ID. Parse.ly documents it as the site identifier on every collect beacon. Fix: Set `idsite` to the Site ID from Parse.ly Support, such as `example.com`. vendor.parsely-collect.param.idsite.missing
vendor.parsely-collect.param.idsite.empty		 docs
url required It is the page URL. Parse.ly documents it as a full URL, not a relative path. Fix: Send the absolute page URL in `url`. vendor.parsely-collect.param.url.missing
vendor.parsely-collect.param.url.empty
vendor.parsely-collect.param.url.invalid		 docs
action recommended Built-in events and custom event names are supported. A leading underscore on custom names is recommended to avoid collisions. Fix: Send `action=pageview` for a page view. vendor.parsely-collect.param.action.missing
vendor.parsely-collect.param.action.empty		 docs
rand… optional It is an integer tracker field. Parse.ly documents `rand` / `sts` / `slts` as millisecond timestamps, `plid` / `pvid` / `sid` as ids, and `inc` as heartbeat seconds. `slts` is `0` on a first session. Fix: Send an integer, such as `0` or a millisecond timestamp. vendor.parsely-collect.param.rand.empty
vendor.parsely-collect.param.rand.invalid		 docs
urlref optional It is the HTTP referrer. Parse.ly documents a full URL, or blank when the reader typed the address. Fix: Send an absolute referrer URL in `urlref`, or leave it blank. vendor.parsely-collect.param.urlref.empty
vendor.parsely-collect.param.urlref.invalid		 docs
sref optional It is the session's first referrer. Parse.ly documents that it can be blank. Fix: Send an absolute URL in `sref`, or leave it blank. vendor.parsely-collect.param.sref.empty
vendor.parsely-collect.param.sref.invalid		 docs
surl optional It is the session's first pageview URL. Fix: Send the absolute first-page URL in `surl`. vendor.parsely-collect.param.surl.empty
vendor.parsely-collect.param.surl.invalid		 docs
screen optional It is the client resolution. Parse.ly documents `WIDTHxHEIGHT|availableWIDTHxavailableHEIGHT|pixelDepth`. Fix: Send `screen` as `1920x1080|1920x1040|24`. vendor.parsely-collect.param.screen.empty
vendor.parsely-collect.param.screen.invalid		 docs
data optional It is optional JSON. Parse.ly documents conversions, audience segments, and custom data here, and allows a blank value. Fix: Send a JSON object in `data`, or leave it blank. docs
title optional It is the content title shown in the Parse.ly dashboard. Fix: Send the headline in `title`, or drop the empty pair. vendor.parsely-collect.param.title.empty docs
date optional The live SDK sends Date.toString event time. Older tracker examples also use ISO 8601. Fix: Send `date` as ISO 8601, such as `2026-09-20T15:41:53.000Z`. vendor.parsely-collect.param.date.empty
vendor.parsely-collect.param.date.invalid		 docs
u optional It is the pseudonymous device UUID. Fix: Send the device UUID in `u`, or drop the empty pair. vendor.parsely-collect.param.u.empty docs
sid optional The vendor documents `sid` in the request contract. Minimum numeric value: 0. vendor.parsely-collect.param.sid.empty
vendor.parsely-collect.param.sid.invalid		 docs
sts optional The vendor documents `sts` in the request contract. Minimum numeric value: 0. vendor.parsely-collect.param.sts.empty
vendor.parsely-collect.param.sts.invalid		 docs
slts optional The vendor documents `slts` in the request contract. Minimum numeric value: 0. vendor.parsely-collect.param.slts.empty
