# S2S with customers 3DS

# How it works

This integration is suitable if you are entirely managing the 3DS service on your end.

POST flow

# Integration steps

# Perform 3DS authentication

If your use-case requires it, make sure to perform any necessary 3DS steps on your end before reaching our API. E.g. when the customer is present and making a payment, 3DS is almost always required.

# Create an authorization

Prepare an authorization creatable object.

{
  "number": "<merchant_tx_id>",
  "amount": 7.52,
  "currency": "EUR",
  "card":  {
    "pan": "4111111111111111",
    "expires": [2, 22],
    "csc": "987",
    "verification": {
      // <3DS Data>
    }
  },
  "browser": {
      "ip": "213.138.91.2", // REQUIRED with Server-Server flow
      "ipCountry": "SE" // REQUIRED with Server-Server flow
  }
}

# Add 3DS data to the authorization

If customer has gone through the 3DS flow, the authorization is required to contain a Verification object with the resulting 3DS data.

All data in the example is required.

  "verification": {
    "data": {
      "authenticationValue": "<string>",
      "dsTransID": "<string>",
      "messageVersion": "2.1.0" | "2.2.0",
      "messageType": "RReq" | "ARes",   
      "eci": "<string>",
      "threeDSServerTransID": "<string>",
      "transStatus": "Y" | "N" | "U" | "A" | "C" | "R"
    }
  }

# Send the request

 





  POST <base_url>/authorization

  Content-Type: application/json

  AuthorizationObject

# Receive a response

The authorization response will be either:

  1. A "Verification required" error response with status 400, indicating that 3DS data was not provided
  2. A successful authorization response with status 201, indicating authorization was approved by the issuer
  3. A failed authorization with reasons of failure.

# Example

A full example can be accessed from the github repository or downloaded as a html file. To test the code, a public api key without 3D configurations is required to be added to the const key in the code.
