I want to analyze and investigate Mercari's private API. Especially Mercari's login API and login access token. There is a URL of Mercari API. However, an error will occur if normal access is performed. How can I get an access token using the API? A request parameter is required to obtain an access token. I want you to investigate this parameter. I also want to analyze the code created in C #. API can be provided. Please tell me the cost of the survey.
I have worked for about three months during my internship with involved major API integration and using third party API .I can assure you desired delivery on time.
