  • Third-party APIs are software tools that allow different systems and applications to communicate with each other. They provide a set of instructions and protocols for how different pieces of software can interact with one another. Whether you are a small startup or an established enterprise, using third-party APIs can greatly benefit your business.

  • When selecting a third-party API, we make a previous research: explore the requirements, consider compatibility with your platform and business needs, and assess the development support needed.

  • The time it takes to integrate a third-party API can vary depending on the complexity of your platform and the API itself. However, with planning and testing included, the integration can typically be completed within a few weeks.

  • Third-party APIs often provide sufficient security measures to protect user data and prevent unauthorized access. However, it is important to analyze the security protocols and measures of a third-party API before integrating it into the platform.

  • Certainly! We are able to provide support and updates to ensure your platform runs smoothly and continues to grow. As long as you see our work in action, we can work on new features development, the user experience enhancement or new integrations for your platform. Feel free to reach out for any development needs.

Ryan Wynch

Program Lead

Design Key did an excellent job by turning a concept into a working MVP that I could provide to my users. They know how to make the development process look easy, highlight underground stones, and suggest features and enhancements. Though I had a complex product, it was delivered on time and to spec. Highly recommended.

Lori Barao

Manager of Operations at MMI Direct

Design Key has worked on several development projects for me over the past two years. They are excellent experts with exceptional client service and communication skills. They are able to dig through complex project requirements and produce an end product that exceeds expectations.

Henry Biggs


Design Key is spectacular, and they do consistently exceptional work. There hasn't been anything they've told me they can't do… And I've asked for a lot over the years! I could not recommend them more highly.
