Real-Time Payments Authorization with Memgraph

In the webinar, Martin Vo, the CTO of Paysure Solutions, offers insights into their experience using Memgraph for real-time payment authorization and enforcing various intricate rules. These rules span basic merchant categories and similarity or frequency checks to more complex insurance criteria. Utilizing Memgraph enabled them to achieve remarkably fast response times for their authorization service. This allowed them to determine promptly whether a payment should be authorized and record the expenditure — all with a single query. In effect, they replaced their complex payments stack, including aggregation workers, locking services, and message queues with Memgraph.

However, their journey with Memgraph was not without challenges. A significant hurdle was the size of their authorization query, which consisted of approximately 700 lines of code with numerous nested procedures. Fortunately, Memgraph's supportive community assisted them in overcoming these challenges, ensuring a production-ready state and preventing payment failures for their customers.
