Quickstart Guide

This document explains how to jump-start your integration with the Account Information API. For more detailed information on endpoint input parameters and response details refer to section Endpoints.

If you are using Postman, you can follow these instructions on how to import Nordigen Account Information Services API schema.


Step 1: Get Access Token

First, you'll need to get your user secret from Nordigen's Open Banking Portal in section User Secrets. Use those secrets to create an access token (referenced as ACCESS_TOKEN in the following steps).

curl -X POST "https://ob.nordigen.com/api/v2/token/new/" 
-H  "accept: application/json" 
-H  "Content-Type: application/json" 
-d "{
     \"secret_id\":\"string\",
     \"secret_key\":\"string\"}"

Response:

{
  "access": "string",
  "access_expires": 86400,
  "refresh": "string",
  "refresh_expires": 2592000
}


Step 2: Choose a Bank

Use institutions endpoint to get a list of all available financial institutions in a given country. You will need to provide a two-letter country code (ISO 3166). ID for the chosen bank will be used in the following steps (referenced as institution_id). Use SANDBOXFINANCE_SFIN0000 as institution_id if you wish to try out the Quickstart with the mock up institution (see Sandbox).

See also the guide on how to build an end user interface for selecting a bank.

curl -X GET "https://ob.nordigen.com/api/v2/institutions/?country=gb" 
-H  "accept: application/json" 
-H  "Authorization: Bearer ACCESS_TOKEN"

Response:

[
  {
    "id": "ABNAMRO_ABNAGB2LXXX",
    "name": "ABN AMRO Bank Commercial",
    "bic": "ABNAGB2LXXX",
    "transaction_total_days": "540",
    "countries": [
      "GB"
    ],
    "logo": "https://cdn.nordigen.com/ais/ABNAMRO_FTSBDEFAXXX.png"
  },
[...]
  {
    "id": "REVOLUT_REVOGB21",
    "name": "Revolut",
    "bic": "REVOGB21",
    "transaction_total_days": "730",
    "countries": [
      "GB"
    ],
    "logo": "https://cdn.nordigen.com/ais/REVOLUT_REVOGB21.png"
  },
]

Step 3: Create an end user agreement

N.B. Use this step only if you want to specify other than default end user agreement terms: 90 days of transaction history, 90 days of account access period and full scope of information (details, balances, transactions). If no custom end user agreement is created default terms will be applied.

You need to create an agreement and pass:

  • institution_id from Step 2.

and optionally: 

  • max_historical_days as the length of the transaction history to be retrieved;
  • access_valid_for_days as the length of days while the access to account is valid;
  • access_scope for the scope of information.
curl -X POST 
"https://ob.nordigen.com/api/v2/agreements/enduser/" 
-H  "accept: application/json" 
-H  "Content-Type: application/json" 
-H  "Authorization: Bearer ACCESS_TOKEN"
-d "{  
       \"institution_id\": \"REVOLUT_REVOGB21\", 
       \"max_historical_days\": \"180\", 
       \"access_valid_for_days\": \"30\", 
       \"access_scope\": [
           \"balances\",
           \"details\",
           \"transactions\"],
}"

Response:

{
  "id": "3fa85f64-5717-4562-b3fc-2c963f66afa6",
  "created": "2021-10-25T16:41:09.753Z",
  "max_historical_days": 180,
  "access_valid_for_days": 30,
  "access_scope": [
    "balances",
    "details",
    "transactions"
  ],
  "accepted": "",
  "institution_id": "REVOLUT_REVOGB21"
}

Step 4: Build a Link

You need to create a requisition which is a collection of inputs for creating links and retrieving accounts. For requisition API requests you will need to provide:

  • institution_id from Step 2;
  • redirect URI where the end user will be redirected after finishing authentication in financial institution;

and optionally:

  • reference as a unique ID defined by you for internal referencing;
  • agreement as end user agreement ID from Step 3;
  • user_language to enforce a language for all end user steps hosted by Nordigen passed as a two-letter country code (ISO 639-1). If user_language is not defined a language set in browser will be used to determine language.
curl -X POST "https://ob.nordigen.com/api/v2/requisitions/" 
-H  "accept: application/json" 
-H  "Content-Type: application/json" 
-H  "Authorization: Bearer ACCESS_TOKEN" 
-d "{  
      \"redirect\": \"http://www.yourwebpage.com\", 
      \"institution_id\": \"REVOLUT_REVOGB21\",
      \"reference\": \"124151\", 
      \"agreement\": \"2dea1b84-97b0-4cb4-8805-302c227587c8\", 
      \"user_language\":\"EN\" }"

Response:

{
  "id": "8126e9fb-93c9-4228-937c-68f0383c2df7",
  "redirect": "http://www.yourwebpage.com",
  "status": {
    "short": "CR",
    "long": "CREATED",
    "description": "Requisition has been succesfully created"
  },
  "agreements": "2dea1b84-97b0-4cb4-8805-302c227587c8",
  "accounts": [],
  "reference": "124151",
  "user_language": "EN",
  "link": "https://ob.nordigen.com/psd2/start/3fa85f64-5717-4562-b3fc-2c963f66afa6/{$INSTITUTION_ID}"
}

Follow the link to start the end-user authentication process with the financial institution. Save the requisition ID (id in the response). You will later need it to retrieve the list of end-user accounts.

 


Step 5: List accounts

Once the user is redirected back to the link provided in Step 4, the user's bank accounts can be listed. Pass the requisition ID to view the accounts.

curl -X GET "https://ob.nordigen.com/api/v2/requisitions/8126e9fb-93c9-4228-937c-68f0383c2df7/" 
-H  "accept: application/json" 
-H  "Authorization: Bearer ACCESS_TOKEN" 

Response:

{
  "id": "8126e9fb-93c9-4228-937c-68f0383c2df7",
  "status": "LN",
  "agreements": "2dea1b84-97b0-4cb4-8805-302c227587c8",
  "accounts": [
    "065da497-e6af-4950-88ed-2edbc0577d20",
    "bc6d7bbb-a7d8-487e-876e-a887dcfeea3d"
  ],
  "reference": "124151",
}

Step 6: Access accounts, balances, and transactions

There are three separate endpoints for accessing account details, balances, and transactions. See account endpoints to view respective endpoints.

In this quickstart, we will showcase the transactions endpoint, where you need to pass the account ID (see "accounts" from the output of Step 5) to access transaction information. You will need to query each account separately.

curl -X GET "https://ob.nordigen.com/api/v2/accounts/065da497-e6af-4950-88ed-2edbc0577d20/transactions/" 
-H  "accept: application/json" 
-H  "Authorization: Bearer ACCESS_TOKEN"

Response:

{
  "transactions": {
    "booked": [
      {
        "transactionId": "2020103000624289-1",
        "debtorName": "MON MOTHMA",
        "debtorAccount": {
          "iban": "GL53SAFI055151515"
        },
        "transactionAmount": {
          "currency": "EUR",
          "amount": "45.00"
        },
        "bookingDate": "2020-10-30",
        "valueDate": "2020-10-30",
        "remittanceInformationUnstructured": "For the support of Restoration of the Republic foundation"
      },
      {
        "transactionId": "2020111101899195-1",
        "transactionAmount": {
          "currency": "EUR",
          "amount": "-15.00"
        },
        "bankTransactionCode": "PMNT",
        "bookingDate": "2020-11-11",
        "valueDate": "2020-11-11",
        "remittanceInformationUnstructured": "PAYMENT Alderaan Coffe"
      }
    ],
    "pending": [
      {
        "transactionAmount": {
          "currency": "EUR",
          "amount": "-10.00"
        },
        "valueDate": "2020-11-03",
        "remittanceInformationUnstructured": "Reserved PAYMENT Emperor's Burgers"
      }
    ]
  }
}
      

What's next.

Congratulations - you now can connect to end-user bank accounts and access raw account and transaction data. To learn more about the output data structures and see more details behind the keys, please visit accounts, balance and transactions.

Note: although financial institutions are supposed to follow the same recommendations in terms of data structures, this is not always the case. We're filling in the gaps as much as possible, but you should anticipate situations where the amount of data delivered differs between banks, e.g., some banks may include ownerName with the account details, some may opt not to do this. If you spot any specific issues, please don't hesitate to contact us!
