Card Element

A single card input field that collects card number, expiry, and CVC in one compact element. Ideal when you want a simple card form with your own submit button and surrounding layout.

How it works

1 Create session (server)

2 Initialise SDK (client)

3 Create & mount card element

4 Submit payment

All-in-one card input field

Your own submit button and form layout

element.submitPayment() to process payment

Real-time validation and error display

Automatic 3DS challenge handling

Works with HTML/JS and React

Before getting started

1. Get your credentials

1 Request a development store with an ecommerce subscription from your Teya contact

2 Log in to the Staging Business Portal with your Teya ID

3 Select your store and go to Integrations

4 Create ecommerce API credentials and configure webhook URLs

You'll receive a Client ID and Client Secret for OAuth authentication

Use client_credentials grant to obtain access tokens

Each store has its own set of credentials

Staging vs Production

Use Staging for development and testing. When ready to go live, repeat the credential setup in Production. Keep separate credentials and token caches for each environment.

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

Integrating on behalf of the merchants you serve?

Partners and platforms get credentials through the merchant registration flow instead. See Take payments online for partners.

Install the SDK

npm install @teyaproduct/teya-blocks-js

For React applications, also install the React wrapper:

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

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

Customize - Themes, CSS variables, and element options
Split Card - Separate card number, expiry, and CVC fields
Apple Pay - Native Apple Pay button
Webhooks - Receive payment confirmation notifications
Testing - Test cards and integration checklist
