Adobe Audience Manager UUID requests follow the DCS identity contract.

The generic DCS /id surface permits optional request attributes. Identity pairs use the documented separators. A request with d_ver, d_orgid, or d_mid is routed to the Experience Cloud ID contract instead.

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
`d_mid`	optional	It is an existing ECID. Adobe's reuse call sends d_mid with d_ver=2. Fix: Send d_mid when you already have an Experience Cloud ID for the visitor.	`vendor.adobe-dcs-id.param.d_mid.empty`	docs
`d_cid`	optional	Provider ID or integration code with user ID separated by %01. Single pairs may include0/1/2authentication state. The generic DCS table permits multiple provider/user pairs in one parameter; the CID guide also permits repeated keys.	`vendor.adobe-dcs-id.param.d_cid.empty` `vendor.adobe-dcs-id.param.d_cid.invalid`	docs
`d_cb`	optional	The vendor documents `d_cb` in the request contract.	`vendor.adobe-dcs-id.param.d_cb.empty`	docs
`d_cid_ic`	optional	Provider ID or integration code with user ID separated by %01. Single pairs may include0/1/2authentication state. The generic DCS table permits multiple provider/user pairs in one parameter; the CID guide also permits repeated keys.	`vendor.adobe-dcs-id.param.d_cid_ic.empty` `vendor.adobe-dcs-id.param.d_cid_ic.invalid`	docs
`d_caller`	optional	Caller identification; no published character grammar.	`vendor.adobe-dcs-id.param.d_caller.empty`	docs
`d_coppa`	optional	Disables third-party-cookie use. Published table specifies behavior without a complete literal-value enum.		docs
`d_cts`	optional	Optional account-enabled traits/segments return mode:1legacy segment IDs or2current IDs.	`vendor.adobe-dcs-id.param.d_cts.empty` `vendor.adobe-dcs-id.param.d_cts.invalid`	docs
`d_dpid`	optional	Deprecated data provider ID, still supported in ID and event calls.	`vendor.adobe-dcs-id.param.d_dpid.empty`	docs
`d_dpuuid`	optional	Deprecated provider-specific user ID, still supported in ID and event calls.	`vendor.adobe-dcs-id.param.d_dpuuid.empty`	docs
`d_dst`	optional	Include URL destination data in a JSON response.	`vendor.adobe-dcs-id.param.d_dst.empty` `vendor.adobe-dcs-id.param.d_dst.invalid`	docs
`d_dst_filter`	optional	Reserved Analytics/Audience Manager integration attribute with unpublished value grammar.		docs
`d_jsonv`	optional	Response JSON version1;0disables ID syncs.	`vendor.adobe-dcs-id.param.d_jsonv.empty` `vendor.adobe-dcs-id.param.d_jsonv.invalid`	docs
`d_nsid`	optional	JavaScript container namespace used by DIL for ID synchronization; account namespace registration is external.	`vendor.adobe-dcs-id.param.d_nsid.empty`	docs
`d_ptfm`	optional	Published platform literal registry.	`vendor.adobe-dcs-id.param.d_ptfm.empty` `vendor.adobe-dcs-id.param.d_ptfm.invalid`	docs
`d_rs`	optional	Deprecated reserved Analytics/Audience Manager attribute, without a published value grammar.		docs
`d_rtbd`	optional	JSON response selector. Required when a JSON response is requested; absence returns a pixel.	`vendor.adobe-dcs-id.param.d_rtbd.empty` `vendor.adobe-dcs-id.param.d_rtbd.invalid`	docs
`d_sid`	optional	Trait/segment score ID; membership is account configuration.	`vendor.adobe-dcs-id.param.d_sid.empty`	docs
`d_tdpid`	optional	Data source for trait evaluation. Public examples use/event, and the linked generic DCS table does not exclude/id.	`vendor.adobe-dcs-id.param.d_tdpid.empty`	docs
`d_tdpid_ic`	optional	Integration-code form of trait-evaluation data source. Source uses/event examples without declaring/id exclusion.	`vendor.adobe-dcs-id.param.d_tdpid_ic.empty`	docs
`d_uuid`	optional	Audience Manager visitor UUID when absent from cookie; numeric-only grammar is not published in this table.	`vendor.adobe-dcs-id.param.d_uuid.empty`	docs
`h_host`	optional	Client collection hostname represented as DCS HTTP-header attribute, without a complete serialized query grammar.		docs
