A robust set of tools and resources

Smart API

We've applied best practices in designing Finexer API making it flexible and easy to adopt. It uses the industry-leading REST-based service that meets the unique needs of every business.

Expert developer support

We offer a seamless, reliable experience, and we’ll work with you and the financial institution to put things right and solve your case including answering API-related and technical queries.

Free live and sandbox accounts

Managing multiple businesses with multi-Finexer account feature, and sandbox accounts for testing end-to-end integration not affecting live environment is free of charge.

Designed for Developers

We understand how tricky integrating various applications can be, which is why at Finexer, we aim to keep working towards developing a useful, scalable API infrastructure, with 99.99% uptime.
