What Is an Open Banking Data Provider Platform?
What an open banking data provider platform does, who needs one, and what capabilities to look for. A guide for banks and financial institutions.
As open banking regulations roll out across the world, financial institutions face a common requirement: share customer data securely with authorised third parties through standardised APIs. A data provider platform is the infrastructure layer that makes this possible.
Whether you're called a data holder (Australia), an ASPSP (UK and Europe), or a data provider (US under Section 1033), the obligation is the same — expose customer account data via APIs when the customer consents to share it. A data provider platform handles the technical, security, and compliance requirements so your institution can meet this obligation without building everything from scratch.
What a Data Provider Platform Does
At its core, a data provider platform sits between your institution's core banking systems and the external ecosystem of fintechs, aggregators, and other third parties that need access to customer data. It handles:
Standardised API Layer
Your core banking system stores customer data in its own format. A data provider platform transforms this data into standardised API responses that conform to the relevant open banking standard — whether that's the Consumer Data Standards (Australia), FDX (US), UK Open Banking Standard, or PSD2-compliant formats (EU). This normalisation layer means you don't need to rebuild your core systems to comply.
Consent Management
Open banking is consent-driven. Customers must explicitly authorise what data is shared, with whom, and for how long. A data provider platform manages the entire consent lifecycle:
- Consent collection — presenting clear, understandable consent requests to customers
- Scope management — enforcing granular permissions (e.g., account details only, or accounts plus transactions)
- Time-boxing — limiting data access to the approved consent period
- Revocation — allowing customers to withdraw consent at any time
- Consumer dashboard — giving customers visibility into who has access to their data
Security and Authentication
Financial data requires financial-grade security. A data provider platform implements the security standards required by open banking regulations:
- Financial-grade API (FAPI) security profiles for authentication and authorisation
- Mutual TLS (mTLS) for secure communication between parties
- OAuth 2.0 with additional security extensions for token management
- Multi-factor authentication (MFA) integration with your existing identity systems
Third-Party Registry and Vetting
Before sharing data, you need to verify that the requesting party is authorised to receive it. A data provider platform maintains a registry of accredited third parties, validates their credentials against the relevant regulatory directory, and applies risk scoring to incoming requests.
Monitoring and Audit
Regulatory compliance requires a clear record of every data access event. A data provider platform provides:
- Immutable audit logs of all data requests and responses
- Real-time monitoring of API performance, uptime, and error rates
- Usage analytics showing data-sharing patterns and volumes
- Regulatory reporting capabilities
Who Needs a Data Provider Platform
Any financial institution with a regulatory obligation to share customer data through open banking APIs needs data provider infrastructure. Specifically:
Banks
In most open banking regimes, banks are the first institutions required to share data. In Australia, the four major banks went live in 2020, with smaller ADIs following. In the UK, the CMA9 banks led the way. In the US, Section 1033 will require banks to provide standardised data access. If you're a bank of any size operating in a regulated market, a data provider platform is either already required or will be soon.
Non-Bank Lenders
In Australia, non-bank lenders with over $1 billion in resident loans are being brought into CDR from 2026. BNPL providers, mortgage lenders, and consumer finance companies all need data provider infrastructure to meet their new obligations.
Energy Retailers
In Australia, energy retailers in the National Electricity Market with 10,000+ small customers are already required to share product and consumer energy data through CDR APIs.
Other Financial Institutions
As open banking expands to open finance, wealth managers, insurers, and other financial service providers may be brought into scope. Having data provider infrastructure in place makes future expansion straightforward.
Build vs. Buy
Financial institutions face a fundamental choice: build data provider infrastructure in-house or use a managed platform.
Building In-House
Building your own data provider infrastructure means:
- Implementing the full open banking API specification from the relevant standard
- Building consent management flows and consumer dashboards
- Implementing FAPI-compliant security (a significant engineering effort)
- Connecting to the regulatory directory for third-party verification
- Building monitoring, audit logging, and reporting systems
- Maintaining ongoing compliance as standards evolve (they update regularly)
This approach gives maximum control but requires a dedicated team and ongoing investment. Standards updates alone can require months of engineering work each year.
Using a Managed Platform
A managed data provider platform handles the API layer, security, consent management, and compliance for you. Your team focuses on integrating the platform with your core banking system — typically a 6–8 week project — and the platform handles everything else, including keeping up with standards changes.
For most institutions, the managed approach is faster, cheaper, and lower risk. The exception is the largest banks with existing API teams and a strategic investment in owning the full technology stack.
Key Capabilities to Evaluate
When evaluating data provider platforms, look for:
Multi-standard support. If you operate across jurisdictions, you need a platform that supports multiple open banking standards (CDR, FDX, UK OB, PSD2) without requiring separate implementations for each.
Granular consent controls. Basic consent management isn't enough. Look for scope-based permissions, time-boxing, bundled consents, and policy-as-code governance that lets you define field-level allow/deny rules and data masking.
Core banking integration flexibility. Your platform needs to connect to your specific core banking system. Look for pre-built connectors or a flexible integration layer that can normalise data from any source system.
Security certifications. SOC 2 Type II, FAPI conformance, and other relevant security certifications are the baseline. Ensure the platform meets the security requirements of your regulators and your own security team.
Uptime and performance. Open banking APIs need to be available 24/7 with low latency. Regulatory standards often define minimum performance thresholds. Look for platforms with 99.9%+ uptime guarantees.
Scalability. Data-sharing volumes grow as more third parties connect and more customers consent. The platform needs to handle increasing load without degradation.
Standards currency. Open banking standards are updated regularly. A good platform keeps your APIs compliant with the latest version without requiring major re-engineering from your side.
The Global Landscape
Data provider obligations exist in varying forms across the world:
- Australia — Consumer Data Right (CDR) with the Consumer Data Standards. Banks, energy retailers, and soon non-bank lenders.
- United States — Section 1033 of the Dodd-Frank Act, with the CFPB's Personal Financial Data Rights Rule. Financial Data Exchange (FDX) is the dominant API standard.
- United Kingdom — The UK Open Banking Standard, overseen by the FCA. Moving toward Smart Data expansion under the Data Protection and Digital Information Act.
- European Union — PSD2 currently, with PSD3 expected to bring enhanced data-sharing requirements. The Financial Data Access (FiDA) regulation will extend to insurance, investments, and pensions.
- New Zealand — Customer and Product Data Act, closely aligned with Australia's CDR.
- Brazil — Open Finance Brasil, one of the most comprehensive frameworks globally, covering banking, insurance, investments, and pensions.
For institutions operating across multiple markets, a data provider platform that supports multiple standards from a single deployment significantly reduces complexity.
