Hi!
My name is Eliot.
I have previous experience with Betfair API.
I was able to complete the following project, which had to gather data for all events in Betfair:

I passed some aspects of Betfair, such as using an App key to connect, parsing Json format for navigation data, and others. This will help me comply with your requirements.
Please let me know if interested.
Best regards.
Eliot
