​
API Endpoint Overview

The card submission API processes payment transactions by accepting card details and customer information.

​
Base URL

  • Test Environment: https://test.paysight.io

​
Endpoint

  • Method: POST
  • Path: /api/{productId}

​
Step-by-Step Integration

​
Step 1: Authentication Setup

The API uses API key authentication passed in the Authorization header. 
'Authorization':  'your-api-key-here',
'ClientId': 'your-client-id',
'UserEmail': 'your-paysight-account-email',
'Content-Type':  'application/json'

​
Step 2: Prepare Request Payload

The API expects a comprehensive payload with card, customer, and transaction details.

​
Minimum Required Request Body (JSON)

{
  "paysightSession": null, // required if partnerSession is null
  "partnerSession": "abcdefg12345", // required if paysightSession is null
  "card": {
    "name": "John Smith",
    "pan": "4111111111111111",
    "expiryMonth": 12,
    "expiryYear": 2029,
    "cvv": "333"
  },
  "email": "johnsmith@gmail.com",
  "amount": 1.00
}

​
Session Management

ParameterTypeDescription

partnerSessionstringPartner/client assigned unique identifier of the session/user visit. Persist this value between calls for the same user session.

​
Step 3: Make a Request to API

​
Base URL

  • Test Environment: https://test.paysight.io

​
Endpoint

  • Method: POST
  • Path: /api/{productId}

​
Step 4: Handle the Response

The API returns a comprehensive response with transaction details: 
{
  "paysightSession": "<string>",
  "partnerSession": "<string>",
  "subscribeSuccess": true,
  "chargeSuccess": true,
  "info": "<string>",
  "error": "<string>",
  "email": "<string>",
  "message": "<string>",
  "orderId": 123,
  "descriptor": "<string>",
  "mid": "<string>",
  "threeDSecureId": "<string>",
  "transactionId": "<string>",
  "amount": 1.00
}
If chargeSuccess is false but subscribeSuccess is true, this indicates a successful opt-in.

​
Step 5: Process Response

Use the response from the API to handle as required per your solution. For example:
  • Redirect customer to thank you page if chargeSuccess: true
  • Send the data to your internal system for additional processing and logic
