ACP Envelope Examples

Seven complete, schema-valid ACP envelopes covering the full range of automotive commerce scenarios. Each example is annotated with the scenario context, key metrics, and what makes ACP capture dramatically more than legacy formats. All envelopes validate against acp-schema-v1.0.0.json.

IP Boundary: These examples show the output format of ACP envelopes. The intent confidence values, score calculations, and handoff decisions shown are illustrative. They do not represent any specific producer's algorithms.

👀

Customer is just looking — no contact info, no specific vehicle, no timeline

A visitor lands on the dealership website, asks a general question about SUV inventory, gets a helpful response, and leaves. This is the lowest-signal interaction — but ACP still captures intent, engagement, and the full conversation for future attribution.

Score: 7

4. Price Objection

⚠️

Customer interested but balking at price — mentions a competitor offer

David Kim likes the BMW X3 CPO but says he saw a similar one at a competing dealer for less. The AI handles the objection by differentiating on CPO warranty and features. Customer remains undecided. ACP captures the objection type so the follow-up team knows exactly what to address.

5. Human Handoff

🤝

Customer becomes frustrated — AI escalates to a human agent

A customer is upset about a service issue and the AI determines a human should take over. The handoff object provides the human agent with a full context summary, priority level, and reason — enabling a seamless transition without the customer repeating themselves.

Score: 32

Stage: inquiry

6. Delta Envelope

⚡

A lightweight partial update referencing a parent snapshot

Delta envelopes contain only acp (with parent_envelope_id) and events. They represent partial updates between snapshots. This specification does not define when or how frequently deltas are generated — that is an implementation decision.

Type: delta

2 events

delta-envelope.json

{
  "acp": {
    "version": "1.0.0",
    "protocol": "acp",
    "generated_at": "2025-02-13T15:35:08Z",
    "envelope_id": "acp_1739456508_p3k7n2",
    "parent_envelope_id": "acp_1739456200_x8k2m9"
  },
  "events": [
    {
      "type": "score_updated",
      "timestamp": "2025-02-13T15:35:08Z",
      "data": { "old_score": 47, "new_score": 65 }
    },
    {
      "type": "intent_detected",
      "timestamp": "2025-02-13T15:35:08Z",
      "data": { "type": "FINANCING", "confidence": 0.84 }
    }
  ]
}

Schema enforcement: When parent_envelope_id is non-null, the JSON Schema forbids all other top-level objects besides acp and events. Receivers encountering a delta whose parent is unknown MUST respond with ENVELOPE_CONFLICT (409).

7. Service Request (Non-Sales)

🔧

Customer contacts the dealership about an oil change appointment — not a sales lead

ACP isn't just for sales. Service interactions generate envelopes too, using agent_type: "service_text" and SERVICE_REQUEST intents. The CRM routes these to the service department instead of the BDC.

ACP vs ADF-XML — Side-by-Side

To illustrate the data density difference, here is what Example 2 (Sarah Chen / Camry) would look like as an ADF-XML submission — the legacy industry standard.

ACP Envelope

127

data fields captured

ADF-XML Equivalent

data fields captured

What ADF-XML Loses

Converting the Example 2 envelope to ADF-XML discards:

✗ 3 detected intents with confidence

✗ Lead score (78) and 7 score factors

✗ Full 8-message conversation transcript

✗ 12 behavioral events with timestamps

✗ AI analysis and purchase probability

✗ UTM attribution and device context

✗ Appointment scheduling data

✗ Session linking and sentiment

same lead as ADF-XMLXML

    <!-- Everything else is lost. -->

This is why ACP exists. The same customer interaction that produces 127 structured data fields in ACP gets compressed to 14 flat XML fields in ADF-XML. Every intent, every score factor, every behavioral signal, and the entire conversation transcript — gone. CRMs receiving ADF-XML are making decisions with 89% less data.

ACP Conformance Checklist

An implementation is considered ACP-compliant if it:

Generates envelopes conforming to the published JSON Schema.
Includes all required top-level objects in snapshot envelopes.
Preserves envelope version integrity (acp.version matches declared specification).
Supports snapshot envelopes (delta support is optional but recommended).
Validates inbound envelopes against the schema on receipt.
Returns acknowledgment responses for accepted payloads, including envelope_id echo.

See the full conformance profiles (Producer and Receiver) in the specification for detailed requirements.
