Amplitude group identify needs api_key and a group

Not /identify. Group identify writes account or company properties. identification is JSON with group_type and group_value. HTTP V2 stays vendor/amplitude.

api_key is required

Amplitude documents api_key on GET query and POST form. A path-only /groupidentify is not an identify call.

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
`api_key`	required	It is the project API key. Amplitude documents it as required on GET query and POST form. Fix: Send `api_key` with the Amplitude project API key.	`vendor.amplitude-group-identify.param.api_key.missing` `vendor.amplitude-group-identify.param.api_key.empty`	docs
`identification`	required	It is a JSON identification object or array. Amplitude documents it as required. Each object carries group_type and group_value. Fix: Send `identification` as JSON with `group_type` and `group_value`.	`vendor.amplitude-group-identify.param.identification.missing` `vendor.amplitude-group-identify.param.identification.empty`	docs
`root`	optional	Identification is an object or array of identification objects. Decoded body source: identification. Encoding: json. Native JSON type: object or array. Minimum array items: 1. Maximum array items: 1024.	`vendor.amplitude-group-identify.body.root.invalid`	docs
`root`	optional	Each identification is an object. Body scope: ["[]",""]. Decoded body source: identification. Encoding: json. Native JSON type: object.	`vendor.amplitude-group-identify.body.root.invalid`	docs
`group_type`	required	The vendor documents `group_type` in the request contract. Body scope: ["[]",""]. Decoded body source: identification. Encoding: json. Native JSON type: string.	`vendor.amplitude-group-identify.body.group_type.missing` `vendor.amplitude-group-identify.body.group_type.empty` `vendor.amplitude-group-identify.body.group_type.invalid`	docs
`group_value`	required	The vendor documents `group_value` in the request contract. Body scope: ["[]",""]. Decoded body source: identification. Encoding: json. Native JSON type: string.	`vendor.amplitude-group-identify.body.group_value.missing` `vendor.amplitude-group-identify.body.group_value.empty` `vendor.amplitude-group-identify.body.group_value.invalid`	docs
`group_properties`	optional	The vendor documents `group_properties` in the request contract. Body scope: ["[]",""]. Decoded body source: identification. Encoding: json. Native JSON type: object. Maximum object properties: 1024.	`vendor.amplitude-group-identify.body.group_properties.invalid`	docs
`group_properties.$set`	optional	The vendor documents `group_properties.$set` in the request contract. Body scope: ["[]",""]. Decoded body source: identification. Encoding: json. Native JSON type: object.	`vendor.amplitude-group-identify.body.group_properties.$set.invalid`	docs
`group_properties.$setOnce`	optional	The vendor documents `group_properties.$setOnce` in the request contract. Body scope: ["[]",""]. Decoded body source: identification. Encoding: json. Native JSON type: object.	`vendor.amplitude-group-identify.body.group_properties.$setOnce.invalid`	docs
`group_properties.$add`	optional	The vendor documents `group_properties.$add` in the request contract. Body scope: ["[]",""]. Decoded body source: identification. Encoding: json. Native JSON type: object.	`vendor.amplitude-group-identify.body.group_properties.$add.invalid`	docs
`group_properties.$append`	optional	The vendor documents `group_properties.$append` in the request contract. Body scope: ["[]",""]. Decoded body source: identification. Encoding: json. Native JSON type: object.	`vendor.amplitude-group-identify.body.group_properties.$append.invalid`	docs
`group_properties.$prepend`	optional	The vendor documents `group_properties.$prepend` in the request contract. Body scope: ["[]",""]. Decoded body source: identification. Encoding: json. Native JSON type: object.	`vendor.amplitude-group-identify.body.group_properties.$prepend.invalid`	docs
`group_properties.$unset`	optional	The vendor documents `group_properties.$unset` in the request contract. Body scope: ["[]",""]. Decoded body source: identification. Encoding: json. Native JSON type: object.	`vendor.amplitude-group-identify.body.group_properties.$unset.invalid`	docs
`group_properties.$add.number…`	optional	The vendor documents `group_properties.$add.number` in the request contract. Body scope: ["[]",""]. Decoded body source: identification. Encoding: json. Native JSON type: number.	`vendor.amplitude-group-identify.body.group_properties.$add.number.invalid`	docs
`method`	required	Use a published Identify transport. Complete HTTP capture contract. Native JSON type: string.	`vendor.amplitude-group-identify.http.method.missing` `vendor.amplitude-group-identify.http.method.empty` `vendor.amplitude-group-identify.http.method.invalid`	docs
`content_type`	required	POST Identify uses form fields rather than a native JSON request body. Complete HTTP capture contract. Applies when {"kind":"value_in","param":"method","values":["POST"]}.
