Our Strategy

Before starting with the designing and development process, it was important for us to understand HelloSign and its core functions properly. Then we searched for many websites that provide the same functionality.  After that checked integrations, but they were not providing direct integration with HelloSign, so we created a small API app to make a bridge between both applications. We analyzed the requirements, its various functions and then created a step by step strategy.
