API Documentation

You can use the Sonder API to easily integrate into any of our supported core banking platforms. If you want to check if a specific platform is supported, please email founders@sonderlabs.io. Sonder allows you to use a standardized data schema to build out proof of concepts, easily scale your code across core banking systems, and build out CI/CD pipelines across disparate data platforms.

Getting started

To get started, create a new developer account and go to your developer settings. Save your API key somewhere safe, then get ready to build the future of banking products. When your BankTech product is ready to go live with a partner financial institution, reach out to us at founders@sonderlabs.io, or our dedicated developer slack channel.
