Account Aggregator

Overview

Account Aggregator V2 provides a robust set of APIs designed to facilitate secure, consent-based financial data aggregation and retrieval from multiple financial institutions. This category enables developers to seamlessly initialize data aggregation sessions, refresh financial information in real-time, and retrieve comprehensive financial statements in multiple formats. The APIs empower fintech applications, lending platforms, and financial service providers to access verified financial data with user consent, streamlining processes like loan underwriting, credit assessment, and financial planning.

Category Details

APIs in this category: Init, Refresh Data, Fetch JSON Report, Fetch Statement PDF

Key Capabilities

Main Functionality

This category provides comprehensive financial data aggregation capabilities through the Account Aggregator framework, enabling secure retrieval of bank statements, transaction histories, and financial reports from multiple institutions through a unified interface. The APIs support both structured (JSON) and document (PDF) formats, with built-in refresh mechanisms to ensure data accuracy and timeliness.

Session Initialization & Consent Management

Initialize secure data aggregation sessions with user consent tracking, establishing authenticated connections to financial institutions while maintaining compliance with data protection regulations and the Account Aggregator framework guidelines.

Real-Time Data Synchronization

Trigger on-demand refresh of financial data from linked accounts, ensuring that applications always work with the most current information for accurate decision-making and analysis in time-sensitive scenarios like loan approvals.

Multi-Format Data Retrieval

Fetch comprehensive financial reports in both machine-readable JSON format for programmatic processing and PDF format for document verification, supporting diverse use cases from automated credit scoring to manual review workflows.

Common Use Cases

Lending & Credit

Wealth Management

Business & Enterprise

Instant Loan Underwriting: Aggregate bank statements and transaction data to automate credit assessment and reduce loan approval time from days to minutes

Credit Score Enhancement: Analyze banking behavior and transaction patterns to provide alternative credit scoring for thin-file or new-to-credit customers

Income Verification: Validate salary credits and income stability for personal loans, mortgages, and credit card applications without manual document collection

Integration Considerations

Best Practices

Implement proper consent workflows: Always obtain explicit user consent before initiating data aggregation, clearly explaining what data will be accessed and how it will be used

Handle refresh cycles strategically: Use the Refresh Data API judiciously to balance data freshness with API rate limits; implement caching strategies for frequently accessed data

Build format-specific processing: Develop separate processing pipelines for JSON and PDF responses, leveraging JSON for automated analysis and PDFs for audit trails and regulatory compliance

Implement robust error handling: Account for network timeouts, institution-specific delays, and consent revocation scenarios with appropriate retry logic and user notifications

Secure data storage: Encrypt aggregated financial data both in transit and at rest, implementing data retention policies that comply with local regulations

Important Limitations

Consent Validity: Data access is dependent on active user consent; expired or revoked consents will result in failed API calls requiring re-authentication

Institution Availability: Data retrieval success rates may vary based on individual financial institution uptime and maintenance windows

Data Latency: Real-time refresh may experience delays ranging from seconds to minutes depending on the source institution's response time

Format Differences: PDF statements may have varying structures across institutions; JSON reports provide standardized format but may have institution-specific field variations

Rate Limits: Excessive refresh requests may be throttled; implement appropriate cooldown periods between refresh calls for the same account

How APIs in this Category Work Together

The Account Aggregator V2 APIs are designed to work in a coordinated sequence, creating a complete data aggregation lifecycle from initialization through retrieval. Each API serves a specific purpose in the workflow, with outputs from one API serving as inputs or triggers for subsequent calls.

Key Integration Patterns:

Init + Refresh Data: After initializing a data aggregation session with user consent, use Refresh Data to trigger immediate synchronization of the latest financial information from linked institutions before fetching reports

Refresh Data + Fetch JSON Report: Once data refresh is complete, retrieve the structured JSON report for programmatic analysis, enabling automated credit scoring, risk assessment, or financial health checks

Fetch JSON Report + Fetch Statement PDF: Combine structured data analysis with document retrieval by fetching both JSON for automated processing and PDF statements for audit trails, regulatory compliance, or manual review by underwriters

A typical end-to-end workflow begins with the Init API establishing a secure session and capturing user consent to access specific accounts. Once initialization succeeds, call the Refresh Data API to ensure you're working with the most current information—particularly important for time-sensitive decisions like loan approvals. After the refresh completes, use Fetch JSON Report to retrieve structured transaction data for automated analysis (calculating average balances, identifying recurring payments, detecting financial stress signals), and simultaneously call Fetch Statement PDF to obtain official bank statements for regulatory compliance, document verification, or situations requiring human review. This comprehensive approach ensures you have both machine-readable data for scalable automation and human-readable documents for transparency and compliance.

The Account Aggregator V2 category integrates seamlessly with other financial data and verification APIs to create comprehensive financial service solutions. These related categories complement the data aggregation capabilities by adding verification, analysis, and alternative data sources.

Related Categories include:

Bank Verification APIs: Use Account Aggregator data alongside penny-drop verification and bank account validation APIs to create multi-layered identity and account ownership verification workflows

Credit Bureau & Scoring APIs: Enhance traditional credit bureau reports with real-time banking data from Account Aggregator to build more comprehensive credit risk models for underserved segments

GST & Tax Verification APIs: Combine banking transaction data with GST returns and tax filing information to verify business revenue claims and detect discrepancies in B2B lending scenarios

For consumer lending applications, you might first use Bank Verification APIs to validate account ownership, then leverage Account Aggregator V2 to pull detailed transaction histories, and finally cross-reference with Credit Bureau APIs to generate a 360-degree credit profile. In business lending, integrating Account Aggregator V2 with GST Verification APIs enables lenders to correlate claimed revenues in GST returns with actual bank deposits, significantly reducing fraud risk. For wealth management platforms, combining this category with Investment Account APIs (if available) creates a unified financial dashboard spanning both banking and investment portfolios.
