Create a json script to update a database via API

I require a JSON expert who can read and understand an API document, and create a script in accordance with the document to achieve certain objectives. Project Details : I have a set of videos on Wistia (Wistia is a media streaming service) which need to be configured to play in a standard way. Wistia provide an API which allows the videos to be configured via JSON script. Whilst I could configure them manually via the user interface, I have a lot of videos which all need to be updated, so it is worthwhile getting a standalone script written. I need the script to do two things; i) Obtain the first frame image from a set of videos; ii) Set each image as the thumbnail for the video; iii) Configure the 'player' settings e.g. video to play on opening, loop, and no play bar. All of the functions required to achieve these objectives are detailed in the Wistia documentation. Here is a link to the Wistia API wiki [login to view URL] I'm keen to find a quality programmer who is an expert in JSON and who is familiar with reading and understanding API interface documents. I have contacted Wistia support and they have advised me that what I am trying to achieve is straight forward within the API, so I just need someone with the skills to assist me. Before you bid, please confirm that you have reviewed the requirements, opened the url link to the Wistia API wiki, that you are a JSON expert, and with a timeframe for completing the work Any questions please ask
