Flipkart Seller API Usage in PHP or Python 3 - Small Project

Hi, I need just the basic code to be created, more like a function in either PHP or Python for the following function: - When SKU is provided get all the details related to it. The GET Listing/V3 on below mentioned page has the details [login to view URL] - Update SKU Details, mainly the price and quantity Again, details for it is provided on this page: [login to view URL] - Not required, but if possible to fetch all SKU from flipkart. I know basics or Python and PHP, but I am not a pro. This is for my personal use as such so I just need the basic function and I will take care of rest. To use the ABOVE API token is needed, which I will provide. The token will remain same, or if necessary I can provide the token generation code. For a person who has worked with seller API of flipkart or has API knowledge, this should not take long. Please place your bid and mention the word "BEYOURSELF" Thank you.
