Connectors

Why multiple processors?

As your business grows faster, there would be a need to expand payment offerings with more payment processors. This need might arise due to multiple reasons:

• Reducing dependency on a single processor and reducing vendor lock-in

• Introducing a challenger processor for better cost and auth rates

• Launching a business in new geography with a local payment processor

• Offering local or new payment methods for your customers

• Reducing technical downtimes and improving success rates with a fallback

Integrating and maintaining multiple payment processors and their different versions is a time and resource intensive process. Hyperswitch can add a new PSP in 2-4 weeks allowing you to focus on you core business activities.

Adding a connector

Most connector integrations follow a simple click-and-connect flow on Hyperswitch using your connector credentials. However, some connectors may require additional setup details as required on the control center. The standard setup steps are as follows :
