Split Card Elements

Separate elements for card number, expiry, and CVC - mount each one wherever you want. Gives you complete control over the card form layout and styling.

How it works

1 Create session (server)

2 Initialise SDK (client)

3 Create & mount each field

4 Submit payment

cardNumber, cardExpiry, cardCvc - each individually mountable

Full layout control between fields

teya.elements.submitPayment() to process

Independent validation per field

Automatic 3DS challenge handling

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

A separate Client ID and Client Secret per merchant

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.

Not registered yet?

Set up your partner account and implement the merchant registration flow first. Teya sends each merchant's credentials to your registration webhook.

2. API URLs

Service	Staging	Production
Online Payments API	`https://api.teya.xyz`	`https://api.teya.com`
OAuth	`https://id.teya.xyz/oauth/v2/oauth-token`	`https://id.teya.com/oauth/v2/oauth-token`
Business Portal	`https://business.teya.xyz`	`https://business.teya.com`

3. Required scopes

Request these scopes when obtaining your access token:

Scope	Description
`transactions/online/create`	Process an online transaction
`transactions/online/id/get`	Get online transaction details
`checkout/sessions/create`	Create a session for the SDK

Install the SDK

npm install @teyaproduct/teya-blocks-js

For React applications:

npm install @teyaproduct/teya-blocks-js @teyaproduct/teya-blocks-react

See SDK Initialization for initTeyaBlocks() options, including developmentMode for staging.
