DevConnect API

We know every business has unique needs when it comes to web developer solutions. That’s why we’ve created our DevConnect product, which makes it easy for developers to integrate their legacy systems with our ACH and credit card back end processors using a single API.Collect payment information through your existing system and seamlessly submit it to E-Complish’s suite of tools for instant authorization.

What is DevConnect?

DevConnect technology is the integration system of choice for companies with the ability to initiate server side and client side SSL connections. This preferred technology gives merchants a high degree of control while securely processing all ACH and credit card transactions. DevConnect is unique in that it is a single web service that transmits both   ACH   and   credit   card transactions through a single API. No more writing two sets of code! Customer payment data travels to the gateway via a server-to-server link launched by the merchant server. The merchant server gets its authorization straight from the E-Complish gateway, providing companies with heightened control over responses to customers.
