UC-15: Group-Buy Lifecycle

Role-gated control-plane steps are intentionally excluded from this public guide; use support escalation when those operations are required. Shared company context: Gharart.com Company Context Need operator help? Escalate through Troubleshooting and Support with request IDs and repro artifacts.

Developer Outcome

Ship group-buy lifecycle for Gharart.com with reproducible API steps, operational limits, and clear debugging playbooks.

Prerequisites

  • A valid handle and environment access for Gharart.com.
  • JWT and/or PAT credentials with required scope for this use case.
  • Access to logs, support escalation endpoints, and test workspace.

Gharart Scenario

Community pre-order campaign for limited-edition decor.

Persona: Community growth manager

Business goal: Publish group-buy offers and track participant interest from public traffic to close conditions.

Step-by-Step Flow (UI + API)

  1. Open the relevant Gharart workflow in the dashboard and confirm actor role access.
  2. Execute route calls in sequence for this use case and capture response IDs.
  3. Validate expected state in UI and API after each step before moving forward.
  4. Record artifacts (request ID, run ID, deployment ID, slug, or token) for support handoff.

Limits and Quotas

  • Respect per-route throttles and daily write limits before bulk operations.
  • Use idempotency-safe retries for write endpoints to avoid duplicate business actions.
  • Schedule high-volume workflows outside peak campaign windows where possible.

Where This Breaks

  • group-buy remains draft due missing publish call
  • interest submissions duplicated from retrying clients
  • close action rejected when threshold conditions not met

How Gharart Debugs It

  1. Check group-buy lifecycle state before every state transition
  2. Verify interest endpoint idempotency behavior for same visitor
  3. Use admin group-buys rollup for campaign-level diagnostics

Escalation

Use end-user escalation path:

  • Submit POST /v2/support/report.
  • Include summary, details, and when available handle, sessionId, requestId, reproArtifact.

Audience boundaries:

  • POST /v2/operator/escalations is an internal operator workflow and not an end-user escalation action.
  • POST /v2/public/content-report is for public abuse moderation reports, not product incident escalation.
