# 91APP Integration Methodology

> **STATUS: SKELETON** — body pending.

## When to use this skill

- Integrating with 91APP via mcp-91app
- Running OMO (online-merge-offline) flows specific to 91APP
- Syncing member data between 91APP and CRM
- Debugging 91APP promotion / coupon flows
- Comparing 91APP vs Shopline for the mid-market DTC segment

## Do NOT use when

- You need generic platform selection guidance → use `tw-ecom-channel-strategy`
- You need 91APP API schema docs → consult mcp-91app README directly

## Core concepts

TODO: 91APP app-first positioning, OMO model, member-centric architecture.

## Decision tree

TODO: which mcp-91app tool for which task.

## Implementation guidance

TODO: order sync, member sync, promotion setup, inventory sync flows.

## Gotchas

TODO: 5-6 pitfalls (candidates: OMO state drift, promotion stacking rules, member merge across web/app, quota limits).

## IRON LAW

TODO: one non-obvious constraint.

## Output Format

TODO.
