Comprehensive guide and documentation to help you start working with smallcase Gateway

Get Started

Web Integration

Step 1 - Include SDK

Adding gateway javascript sdk in the web app & initialization
Gateway provides a JS sdk to be included in your client side code. The sdk is compatible with all major browsers and JS libraries/frameworks

To get started, include sdk’s JS file before your main webapp

<script src=""

Step 2 - Initialize gateway session

Once the sdk has loaded, you will have access to scDK class in the webapp’s JS global scope
An instance of scDK class scGateway can be initialized to access client side sdk methods

const scGateway = new scDK({
  gateway: <gateway_name>,
  smallcaseAuthToken: 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJndWVzdCI6dHJ1ZX0.4-iEdgi3W5_xy7Svj4Sj-FWAe5qMrW3u371FnbjJxQ8',
  config: {
    amo: true

To enable after market orders(AMO) by passing a boolean value to the amo key in the config object in the initialization

Step 3 - Create transactionId

A transactionId is required for the interactions with brokers
TransactionId is created via backend APIs
Interactions & respective APIs below -

  • To place a single or basket stock transaction - API example
  • to place a smallcase order or setup SIP - API example
  • Holdings import -

Step 4 - Trigger transaction

Use triggerTransaction method to start the gateway transaction
It accepts two parameters -

  • transactionId
    Eg: TRX_652377470a134a80ac6c56d19ef3416c
  • brokers
    array of supported brokers, use aliceblue, angelbroking , axis, edelweiss, fivepaisa, hdfc, iifl, kite, trustline & upstox
    All brokers are shown if the key is missing/empty
  transactionId: <transactionId>,
    brokers: ['kite', 'hdfc']
.then(res => res)
.catch(err => err)

Step 5 - Save order response

Order response is shared in the .then block of the triggerTransaction promise as well as over API webhooks
Check response structure here

In case the transaction is not placed with the broker, any error is available in the .catch block
List of transaction errors is available here

Broker Account Opening

Trigger the signup method to start the account opening signup flow.

It accepts an optional parameter -

  • userDetails can have one or more of the following string keys containing user details:
    • name - Full name
    • email - Email address
    • contact - Contact number
    • pinCode - Pin code

The keys inside the userDetails object are optional.

And for all relevant keys passed to the signup method, gateway will pre-populated relevant user data in the signup flow, ensuring a smooth user experience

Example usage

 name: 'Chuck Noris',
 email: '[email protected]',
 contact: '9876543210',
 pinCode: '123456',
.then(() => { console.log("signup flow has now ended") });

Note: In order to trigger signup flow, an instance of scDK class scGateway must be initialized.
