Uphold offers a suite of REST APIs that allow you to interact with our platform programmatically, enabling you to build your application on top of our services. Our REST APIs are modular in principle and can be combined to serve different business needs and to build custom solutions. OpenAPI specifications are available for all our APIs, which is a standard to describe HTTP APIs. You may use these specifications to generate client libraries in your preferred programming language. Our APIs provide fundamental building blocks, forming the backbone of our REST API suite. With these building blocks, you will be able to build a wide range of solutions with a high degree of flexibility.
