Embed a complete checkout form directly in your site using the Checkout Element. It handles card input, 3D Secure, and payment submission - all within a single element you mount to a container.
How it works
1 Create session (server)
2 Initialise SDK (client)
3 Mount checkout element
4 Customer pays inline
Single element - handles everything
Built-in submit button and validation
Customisable with themes and CSS variables
Automatic 3DS challenge handling
onSuccess / onError callbacks
Works with HTML/JS and React
Before getting started
1. Get merchant credentials
As a partner you take payments on behalf of the merchants you serve. Each merchant's Client ID and Client Secret are delivered to your registrationWebhook when the merchant connects Teya to your platform, along with the store_id and payment_webhook_public_key.
Use client_credentials grant to obtain access tokens
Each merchant store has its own set of credentials
Store credentials securely and never expose them in client-side code
```admonition

title: A separate Client ID and Client Secret per merchant
content: Unlike POSLink credentials, these aren't shared across your merchant base. Each merchant you serve gets its own Client ID and Client Secret, delivered to your registrationWebhook when they connect - keep each merchant's credentials separate and don't reuse one set across multiple merchants.
```
```admonition
icon: fas fa-user-plus
title: Not registered yet?
content: Set up your partner account and implement the merchant registration flow first. Teya sends each merchant's credentials to your registration webhook.

Domain Verification
To use Apple Pay within the Embedded Checkout, your domain must be verified with Apple. Follow these steps:
1 Download the domain verification file from the
Business Portal under
Integrations > Apple Pay
2 Host the file at https://yourdomain.com/.well-known/apple-developer-merchantid-domain-association
3 Click Verify in the Business Portal to complete domain verification
```admonition
icon: fas fa-info-circle
title: Domain Verification for Apple Pay
content: Domain verification is only required if you want Apple Pay to appear in the Embedded Checkout. Card payments work without it. Verification must be completed for each domain (including staging and production).
```
