Fronaccounting API integration

My project is for the integration of Fronaccounting API into an existing platform which is builed/developed PHP Laravel framework . The API code will be written in php and used to pull and post data out of the system. I require someone with experience in Frontaccount APIs and in securely integrating them into existing platforms. This candidate should know how to safely lock down the API from unauthorized access, while not compromising the performance of the system. The hired freelancer should be confident in their ability to integrate the API successfully and will have a thorough knowledge of the Fronaccounting system and its capabilities. Thanks for your interest.
