The challenge

Delivering a brand-new financial API platform

UK credit card usage is substantial — around 60 percent of adults own one — and it’s growing year on year. With over 5 million credit customers, our client is a major player in this industry. However, the client recognised that digital innovation was key to maintaining this market-leading position.


This search for increased revenue and market share led the client to consider creating a pioneering digital credit card. This would effectively be a digital version of its “cobrand” credit cards, which high-street chains wrap in their own branding for use as store cards, retail-branded credit cards, and reward cards. As well as the usual credit card functionality, these cards offer benefits such as shopping discounts and loyalty points.


Overall, the client’s business goals with this digital credit card were:


  • to grow their near-prime business by approving more customers for credit
  • to gain greater returns from their existing investment in cobrand credit products


Expanding their cobrand credit cards into a digital format was a fast way to further these goals, as it would help them tap into the online shopping market. However, the client lacked the in-house expertise to make this dream a reality.

The solution

White-label credit card processing with Azure

Aware of our reputation as financial software developers, the client approached the Influential team for a solution. And we determined that the challenge was a perfect use case for an API platform built in Microsoft Azure.


Using Azure’s serverless technologies, our integration engineers developed a suite of interconnected APIs. Each of these performed a specific function, such as performing credit checks and identity checks with third-party databases.


A major benefit of Azure — besides its cost-effective and scalable services — was the free and automatically generated developer portal. This site allowed developers from our client’s partners to use and test the credit card APIs securely and easily. This eased the roll-out of the digital credit card across the client’s partner network, ensuring the new product could gain traction quickly.

The benefits

A financial API platform to beat the competition

Thanks to our fast and flawless delivery of the credit card API integration, our client was in a position to corner the online credit market. This cemented the company’s position as a finance leader and provided a sizeable new revenue stream.


From the client’s perspective, the business benefits of this financial API platform were:


  • disrupting the market with a world-first financial innovation
  • allowing expansion of the client’s credit business into online shops
  • giving partners’ developers safe and easy access to the APIs


And for the customers who adopted the white-label credit card processing solution, the benefits were:


  • a fast and financially compliant way to provide online credit
  • increasing customer loyalty through own-brand credit schemes
  • boosting sales through promotional payment options online


Based on our success in this credit card payment integration project and related work, the client has chosen our team as its go-to system integrators. From GDPR data solutions to customer service integration, the client continues to benefit from our enterprise integration expertise. And each of these projects is showing ongoing returns in the form of greater efficiency, agility, and profitability.

Google Analytics
The cookie _gcl_au is used by Google Analytics to understand user interaction with the website.

For example, in order for Google Analytics to determine that two distinct hits belong to the same user, a unique identifier, associated with that particular user, must be sent with each hit.

The analytics.js library accomplishes this via the Client ID field, a unique, randomly generated string that gets stored in the browsers cookies, so subsequent visits to the same site can be associated with the same user.

By default, analytics.js uses a single, first-party cookie named _ga to store the Client ID, but the cookie's name, domain, and expiration time can all be customized. Other cookies created by analytics.js include _gid, AMP_TOKEN and _gac_. These cookies store other randomly generated ids and campaign information about the user.
