Upload and version your POS APK on the Sunmi Partner Platform. Peach Payments manages the Payment App separately; you own your POS app lifecycle on Sunmi.

Who does what

Responsibility	Who
Build, sign, and upload POS APK	Integrator
Payment App on terminals	Peach Payments
Sunmi channel binding so terminals can install your app	Peach Payments coordinates with your Sunmi partner account

📘
Upload your app as public on the Sunmi Partner Platform so Peach Payments can push it to merchant terminals on your channel.

Partner account setup

Register at partner.sunmi.com and complete company profile verification.
If Development → App Publishing is missing, email [email protected] to request app-publishing access.

Upload a new app

Sign in to partner.sunmi.com.
Open Development → App Publishing (or My APP).
Upload your signed release APK.
Complete metadata:
- App name and description
- Supported device models (P2_SE and P2_LITE_SE)
- Screenshots (minimum 3)
- Region - select overseas / South Africa (not China-only)
- Deploy method - Deploy all or Gray release (see below)
Preview and submit for review.

Payment-series terminals may require manual verification before the app appears in the store. Confirm review timelines with Sunmi for your device series.

Version updates

Select your app → Upgrade.
Upload a new APK with a higher versionCode than the published build.
Submit for review.

On Wi-Fi, devices may receive updates silently when the app is not in the foreground. Reboot the terminal to force a sync if needed.

Gray release (staged rollout)

Use gray release to pilot a version before fleet-wide rollout:

Setting	Options
Deployment method	Deploy all · Gray release deployment
Target	Region or device serial number (SN) list

Recommended: upload → gray release to pilot SNs → verify end-to-end sales → widen to full channel.

APK requirements

Requirement	Detail
Signing	Release APK signed with V1 + V2 signature schemes
`versionCode`	Must increment on every upload
Package name	Must match previous releases for upgrades
ABI	Include `armeabi-v7a` / `arm64-v8a` as required by target models

Sunmi SDKs
