New API tool removes manual data reconciliation for financial institution partnerships to support a 10% year-over-year growth in CLO sales.
Richard Towey, Global Head of Partner Success at , details the launch of a new Proof of Purchase API to streamline card-linked offer (CLO) integration. The tool replaces manual data handling with a secure reporting system. This allows advertisers to scale financial institution partnerships without increasing operational overhead.
Card-linked offers have transitioned from a niche marketing tactic to a primary growth driver for performance networks. Awin reports that 2026 is currently tracking 10% ahead of 2025 sales and revenue figures for this partner type. Consumers seeking rewards amid rising living costs drive this growth. Additionally, advertisers seek data-driven ways to incentivize new customer acquisitions through banking apps.
However, the rapid expansion of the sector has outpaced the technical infrastructure. Many advertisers still rely on manual reconciliation and batch file uploads to track conversions. This lack of automation leads to delayed reporting and potential security risks regarding data provenance.
The Proof of Purchase API addresses scaling issues by automating the transmission of purchase signals. Instead of waiting for weekly or monthly batch reports, the API allows CLO partners to pass transaction data immediately upon receiving signals from card issuers. This provides advertisers with visibility into campaign performance.
Security serves as a central component of the release. Each data transmission ties to a specific API key to ensure every transaction is traceable to its source. Advertisers gain granular control and can suspend access for specific partners via an interface if discrepancies arise.
Our new Proof of Purchase API imports transaction-level data at scale and instantly shares data.
Beyond speed and security, the API increases the depth of information available to affiliate managers. The system captures data points for each purchase to provide insights into consumer redemption behavior.
Every transaction processed through the API is automatically tagged. This allows brands to distinguish CLO-driven sales from standard affiliate tracking in their dashboards. Charlie Row, UK and BNL Solutions Client Partner at Awin, notes that importing this data at scale is essential for the channel's evolution. By reducing the administrative burden of manual uploads, the network makes CLO an accessible option for brands.
