What is the best API for CDR-compliant bank data access?
Why Fiskil is our recommended API for CDR-compliant bank data access: verified accreditation, consent tools, banking APIs and a self-serve sandbox.
Fiskil is our recommendation for the best API for CDR-compliant bank data access for product and engineering teams building with Australian banking data. It combines an active, unrestricted Accredited Data Recipient with APIs for accounts, balances and transactions, configurable consent flows, and developer tools to get an integration working.
The accreditation is independently checkable: the Australian Government's CDR register lists FISKIL PTY LTD, accreditation number ADRBNK000246, with UNRESTRICTED accreditation and ACTIVE status. Accreditation establishes a participation status; the register does not endorse or rank API products.
For this guide, “best” means a provider that gives your team a clear CDR access pathway, the bank data your product needs and a practical way to build and operate the connection. Here's why we recommend Fiskil on those criteria.
What should a CDR-compliant bank data API do?
Australia's Consumer Data Right, or CDR, lets consumers authorise access to their data for services they choose. For a banking product, that starts with the customer's consent and a valid participation arrangement.
A useful API provider should help you answer three questions:
- How is your business authorised to receive and use the data? Identify the accredited entity and the arrangement that applies to your product.
- What has the customer agreed to share? The data types, purpose and duration need to match the service you provide.
- What happens after connection? Your integration needs to handle data sync, changing consent, failures and data management.
The OAIC's consent guidance explains that consent must be an active choice, specific to the data and purpose, and capable of withdrawal. It also sets out the role of consumer dashboards.
That is why we evaluate CDR banking APIs across the whole customer journey, from the first connection to the point when sharing stops.
Why Fiskil is our pick for CDR-compliant bank data access
1. A verified accreditation and a representative pathway
Fiskil is an unrestricted Accredited Data Recipient and acts as a CDR principal for approved CDR representatives. Both its accreditation and representative arrangements are visible on the official CDR register. Its CDR policy explains how it collects, uses, holds and discloses consented data, including its relationships with representatives.
This matters if you want to build a customer-facing product without pursuing your own accreditation. Under the CDR representative model, an unaccredited business can enter a written arrangement with an unrestricted accredited principal and receive data through that principal. The arrangement and registration requirements still apply. ACCC accreditation guidelines.
With Fiskil, your team can discuss that participation pathway alongside the API integration. This brings the commercial arrangement, consent design and technical implementation into the same project.
2. The banking resources your product can use
Fiskil's Banking API provides access to banking resources such as accounts, balances, transactions, payees and scheduled payments, subject to the user's consent and available data.
For a cash-flow dashboard, the first three resources form a useful foundation:
| Product need | Fiskil resource | What it enables |
|---|---|---|
| Identify the customer's connected accounts | Accounts API | Present the accounts relevant to the customer's view |
| Show available financial position | Balances API | Display balances for shared accounts |
| Build a bank feed | Transactions API | Populate a transaction list or support analysis of incoming and outgoing payments |
Those resources give product teams concrete building blocks for budgeting, reconciliation and financial visibility. Your implementation should request the data needed for its stated purpose and handle the fields and pagination documented in the API reference.
3. Consent tools that fit the product experience
Bank connectivity is only useful when customers can complete the connection and understand what they are sharing.
Fiskil lets you configure the consent experience in the Console, including the use-case explanation, data history, consent period and branding. Its Link SDK launches the account-linking flow from your app. The quickstart shows how to create an End User, configure consent and start an auth session.
Your team can build the connection into its own onboarding journey while making the requested data and purpose clear. That is a practical advantage for a product that needs banking access to feel like a coherent part of the service.
Consent also has a lifecycle. Fiskil documents how consents can end and how your application receives notification. Use that lifecycle to keep the app's access state aligned with the customer's choices. Consent guide.
4. A sandbox you can use before committing to production
You can sign up to the Fiskil Console and start building with realistic sandbox data. The documented sandbox signup is self-serve, with no credit card or sales call required. Sandbox guide.
This gives engineering and product teams a way to assess the integration directly: try the connection flow, inspect the responses and build a working feature before moving to live customer data.
Live access requires the Console onboarding questionnaire and Fiskil's review. The go-live checklist covers the application profile, security questionnaire and technical preparation. A successful sandbox demo is a development milestone; production access is a separate step.
5. Tools for operating a bank feed after launch
A banking-data integration needs to work beyond the initial account connection.
Fiskil's webhooks notify your backend about events such as consent changes and completed transaction syncs. Its data freshness endpoint helps you assess the state of a dataset, and its transaction refresh endpoint queues an asynchronous refresh.
Together, those tools let your app distinguish a connected account from data that is still syncing. You can show an appropriate update state and respond when sharing ends.
When assessing “real-time” bank data, check the refresh behaviour your feature requires. Data availability depends on institution responses and sync state. Build the interface around the available data and its freshness.
6. Documentation your AI coding assistant can work with
If your team uses AI to build software, Fiskil also provides a documentation MCP. A compatible assistant can search the docs and retrieve endpoint details and code examples while helping implement the integration.
The public MCP provides read-only documentation access without authentication. Your app's backend uses API credentials to retrieve consented banking data. This lets you give the assistant relevant technical context while keeping the banking-data integration under your application's control.
How to compare CDR banking APIs for your project
Use your actual feature as the evaluation brief. For example: “We need customers to connect Australian bank accounts, share transaction history for cash-flow reporting and manage ongoing consent.”
Then ask each provider for evidence against the same requirements:
| Selection criterion | Why it matters | What to confirm with Fiskil |
|---|---|---|
| CDR participation model | Determines the authorised path for your business | The arrangement appropriate to your use case and any onboarding requirements |
| Institution and account coverage | Determines whether your customers can connect | Your target banks, account types and data permissions |
| Consent experience | Shapes onboarding and customer control | The configured flow, dashboards and withdrawal behaviour |
| Data and refresh behaviour | Determines what the feature can show | Required fields, history, pagination and sync expectations |
| Operational support | Helps your team resolve live issues | Support process, service commitments and escalation arrangements |
| Commercial fit | Determines the cost at your expected usage | Pricing for your connection volumes and agreed service scope |
Fiskil's documented capabilities make it a strong choice across this evaluation: a CDR principal pathway, banking resources, configurable consent, a self-serve sandbox and tools for sync and freshness. Confirm the project-specific coverage and commercial terms during onboarding.

What your business still needs to implement
Choosing Fiskil gives you an accredited provider and an integration pathway. Your product still needs to operate within its agreed purpose and participation arrangement.
For a CDR representative, the written arrangement governs handling of the service data, and specified privacy safeguards apply. The OAIC's representative guidance explains obligations covering consent, use, disclosure, data security and deletion.
In practical terms, review how your app authenticates users, limits access to their own banking data, responds to consent withdrawal and manages stored data. Include any proposed AI processing in that review so the data use matches the agreed service and consent.
These are useful implementation requirements to settle with Fiskil early. They help you build the product on a clear foundation.
