Kickstart Integration
This page just got revamped!
✨ Get started with smallcase Gateway integration -
https://developers.gateway.smallcase.com/docs/getting-started
Prerequisites
In order to start the integration, let's understand the following credentials first -
gateway_name
Unique name used to identify each partner. It is used as part of the Gateway API Url.
secret
secret is unique & confidential for each partner
Used to create smallcaseAuthToken(JWT) for initializing Gateway client side SDK.
apiSecret
apiSecret is unique & confidential for each partner
It is used as a request header to authenticate all Gateway backend API requests
Domain whitelisting
For the Gateway initialization to be successful, please share your development & production domains with us for whitelisting
This is applicable for web integration only
Note
If either of the above four items are not in place, please write to us on [email protected]
Terminologies
Gateway API url
The Gateway API URL is https://gatewayapi.smallcase.com. You need to include this before each API endpoint to make API calls
JWT : JSON Web Tokens
JWT are an open, industry-standard RFC 7519 method for representing claims securely between two parties. Refer https://jwt.io/
Gateway provides a secret (as mentioned in prerequisites) to encode the desired payload & create JWT
Read more on how we are using JWT
Guest user
A user when interacting with the Gateway ecosystem for the first time will have to choose a broker from our list of supported brokers and login with his broker credentials. This user is identified as a guest user in the gateway ecosystem
To initialize a gateway session for such guest user, the JWT has to be created with the following payload
{
guest: true
}
Connected user
Once broker authentication flow is completed by the user, smallcaseAuthId is shared by Gateway as part of the transaction response.
Note: In case of client-side, smallcaseAuthId can be extracted by decoding the smallcaseAuthToken(JWT) received in the response
In case of webhook response, smallcaseAuthId is shared as part of the response data
smallcaseAuthId is a unique ID to identify users between the integration partner & Gateway as well as save his choice of broker.
All subsequent Gateway sessions for this user can be initialized by creating a JWT with smallcaseAuthId as payload.
{
smallcaseAuthId: <smallcaseAuthId string>
}
A connected user will be prompted to login with his choice of broker instead of having to select a broker from available list
