Test your TrueLayer integration

Test our TrueLayer integration by reading test data from the Demo Bank account or an alternative banking source

You can test your TrueLayer banking integration by retrieving test data from the Demo Bank account, or another banking source. We recommend you do this before sending Link URLs to your SMB customers.

You'll need to:

  • Set up a test company and generate a Link URL
  • Connect to a bank account
  • Check your banking data

Then, you can retrieve and check data from the connected bank account.

Prerequisites

Before you start, decide which type of banking source you want to test. This procedure uses the Demo Bank source, which is enabled in the TrueLayer settings in the Codat Portal by default. You'll need to adapt these steps if you choose to use an alternative banking source.

Retrieve the platform key of the Demo Bank data source, or an alternative banking source, and then generate a Link URL.

  1. Log in to the Codat Portal.
  2. Open the GET integrations endpoint.
  3. Send a GET request to return a list of all integrations.
  4. Search for Demo Bank, or the alternative banking source you want to use. All banking integrations have a sourceType of Banking. For example:
{
"key": "demobank_truelayer",
"logoUrl": "https://static.codat.io/public/platforms/demobank_truelayer.png",
"name": "Demo Bank",
"enabled": true,
"sourceId": "22222222-7778-46cc-8544-952fe34a5e3a",
"integrationId": "22222222-b2bf-4213-b594-1fb9474cbaf0",
"sourceType": "Banking"
}

Use these details to create a company; this returns the Link URL you need for testing.

  1. Open the POST /companies endpoint.
  2. Enter a name for your test company and add the platform key for your chosen banking source:
{
"name": "companyname",
"platformType": "demobank_truelayer"
}
  1. Send your request to create the test company and its corresponding Link URL. The response looks something like this:
{
"id": "22222222-9b99-475f-b7e8-4f9a09b9289d",
"name": "companyname",
"platform": "TrueLayer Open Banking",
"redirect": "https://link.codat.io/link/start/22222222-9b99-475f-b7e8-4f9a09b9289d/00dbe10e-8f4a-43c2-935f-45d474576fb7",
"status": "PendingAuth",
"dataConnections": [
{
"id": "22222222-8f4a-43c2-935f-45d474576fb7",
"integrationId": "22222222-b2bf-4213-b594-1fb9474cbaf0",
"sourceId": "22222222-7778-46cc-8544-952fe34a5e3a",
"platformName": "TrueLayer Open Banking",
"linkUrl": "https://link.codat.io/link/start/22222222-9b99-475f-b7e8-4f9a09b9289d/00dbe10e-8f4a-43c2-935f-45d474576fb7",
"status": "PendingAuth",
"created": "2020-06-24T11:13:27.6232806Z"
}
],
"created": "2020-06-24T11:13:25.8263019Z"
}

Copy the JSON response to use in the next procedure.

Connect to a bank account

Bank account login details

If you've chosen to connect to a bank data source other than the Demo Bank, you'll need login details for an account at that institution.

For testing purposes only, follow the process that your customers normally use to authorize a connection to their bank accounts.

  1. In your browser, enter the linkUrl value from the JSON you saved in steps 6 and 7 of the preceding task. The link takes you to a TrueLayer landing page.
  2. Select ALLOW to link the Demo Bank account. A login page is displayed.
  3. For the Demo Bank, enter the test credentials shown on the login page. The account is linked automatically and you return to Link.

You're now ready to start testing.

Check your banking data

You can check data from Demo Bank account in two ways: in the Codat Portal and through the Codat API.

To perform a quick check in the Codat Portal:

  1. On the navigation bar, select Companies, and search for the test company that you created.
  2. Click on the company name.
  3. Select Data > Banking in the side navigation menu.
  4. In the Data type dropdown, select New to show the new banking data types.
  5. Click Banking - Accounts to view accounts and related transaction data.

To retrieve the same data from the Codat API, you'll need the JSON from step 6 of "Set up a test company and generate a Link URL".

To retrieve account details using the Codat API:

  1. Open the GET /companies/{companyId}/connections/{connectionId}/data/banking-accounts endpoint.
    • Replace {companyId} with the id of your test company.
    • Replace {connectionId} with the id from dataConnections.
  2. Send your request to return a list of account details:
{
"results": [
{
"id": "2cbf9b6063102763ccbe3ea62f1b3e72",
"name": "Business Current Account",
"informalName": "Codat",
"holder": "Codat Ltd",
"type": "Debit",
"balance": {
"available": 459987.97,
"current": 459987.97,
"limit": -10000
},
"identifiers": {
"type": "Debit",
"subtype": "Business",
"number": "46762629",
"bankCode": "009911",
"iban": "GB29 LOYD 4773 2346 7626 29",
"bic": "LOYDGB21006",
"maskedAccountNumber": "1111111"
},
"currency": "GBP",
"institution": {
"id": "lloyds-bank",
"name": "Lloyds Bank"
},
"modifiedDate": "2022-06-21T16:14:11.194Z",
"sourceModifiedDate": "2022-06-21T16:14:11.194Z"
}
  1. Optional: Use the GET /companies/{companyId}/connections/{connectionId}/data/banking-transactions endpoint in the same way to retrieve the transactions for each account.

You're now ready to set up and connect your SMB customers. Follow the methods described in Set up a test company and generate a Link URL.
