Introducing Cayan's Test Processor

Dominic Lachowicz

Mock objects play a big role in software development at Cayan. It allows us to decouple our test cases from 3rd party dependencies, such as other credit, debit, gift, or loyalty networks. One of the tools we’ve built simulates a payment processor, such as First Data or Elavon, unimaginatively referred to as our “Test Processor”. Cayan's Test Processor triggers specific responses based on the criteria submitted in your transactions, allowing test cases to work uniformly across all of our products

Merchant Best Practice - Have a WAN Backup Plan

Dominic Lachowicz

Wide area network (WAN) outages are unfortunately a fact of life for many enterprises, whether they are caused by natural disasters, unreliable aging networks, or human errors. A surprisingly large number of merchants experience outages in their stores multiple times a month due to issues with their local ISPs. Having a wireless WAN backup option – such as those provided by cellular 3G and 4G networks - can help keep merchants running in spite of unreliable wired ISPs.

Introducing Cayan’s Public Status Page

Josh Ford

In the software as a service business, service-impacting incidents happen. When a service-impacting incident happens, keeping your users informed of real-time status and setting expectations on what to expect next during an incident is a critical action to take in terms of maintaining a user’s trust and confidence in your service delivery.

Hackathon 3.0 Project - Overlaying maps with data from Splunk

Krisztian Feher & Lewis Reilly

Every day, Cayan amasses gigabytes of machine-generated data – data about our merchants, their transactions, what items they sold. For our hackathon project, our team wanted to add context to this raw data. Our goal was to help support our sales engineering colleagues to get useful, high level information at a glance by looking at a map. We wanted to give our users a way to view their merchants’ activity over time.
