Integration Overview

1. POSLink (Cloud Terminal Integration)

Use when: Your ePOS runs on a separate device (tablet, PC) from the payment terminal.

Platforms: Android, Windows (iOS planned)

Key features:

Cloud-based communication between ePOS and terminal
SDK handles OAuth authentication and token refresh
Pre-built payment UI screens
Minimal setup required

Getting started:

Register at partner.teya.xyz (staging) or partner.teya.com (production)
Create OAuth application (Device Code Flow)
Get Client ID and Client Secret (per partner, not per merchant)
Request mock payment app APK from Partnership Manager
Integrate SDK into your application

2. All-In-One Integration

Use when: Your ePOS app runs on the same Android device as the payment terminal.

Platforms: Android only (Sunmi, PAX terminals)

Key features:

Single-device workflow
Apps communicate via deeplinks
Receipt printing via Sunmi/PAX SDKs
No cloud dependency for device communication

Getting started:

Request debug terminal from Partnership Manager
Specify terminal model (Sunmi or PAX)
Get test merchant account assigned to terminal
Integrate SDK using provided guides

References:

3. E-Commerce API (Online Payments)

Use when: You need to accept online payments (card not present).

Options:

Hosted Checkout - Redirect customers to Teya's secure payment page (best for most merchants)
Payment Links - Send payment links via email/SMS for remote collection
Direct Processing - Full control for PCI-compliant systems

Getting started:

Get Teya merchant account from your representative
Access Business Portal: business.teya.xyz (staging) or business.teya.com (production)
Create API credentials under store settings → Integrations
Configure webhooks for payment notifications
Implement OAuth token exchange

4. Payments Gateway API

Use when: You're building card-present processing with direct API integration (advanced).

Supports:

Card-present transactions (EMV, contactless)
Pre-authorization and capture flows
Refunds and reversals
MOTO transactions
SoftPOS transactions

References:

5. POSLink REST API

Use when: You need programmatic access to stores, terminals, and receipt printing.

Features:

Payment request management
Store configuration
Terminal monitoring
Receipt printing (JSON and image formats)

References:

POSLink API

Authentication

All Teya APIs use OAuth 2.0:

Environments:

Staging: https://id.teya.xyz/oauth/v2/oauth-token
Production: https://id.teya.com/oauth/v2/oauth-token

Token lifetimes:

Production: 15 minutes
Staging: 24 hours

Example token request:

curl -X POST 'https://id.teya.com/oauth/v2/oauth-token' \
  -H 'Content-Type: application/x-www-form-urlencoded' \
  -d 'grant_type=client_credentials' \
  -d 'client_id=<CLIENT_ID>' \
  -d 'client_secret=<CLIENT_SECRET>' \
  -d 'scope=checkout/sessions/create refunds/create'
