    I am building an app that will need to integrate with 3 3rd party API’s. Those API’s don’t have and official SDK for Node and I want a custom solution for the 3 API’s. The three API’s are: Lazada Open Platform API Shopee Open Platform API Line Shopping API Note that I only need maybe 5-10 endpoints from each of the API’s so we don’t need to support all of them. Mainly the endpoint are get and refresh access token, getOrders, getOrderDetails, etc. I will invite you to a Node.js backend app that you can contribute your code to. I am hoping to have this completed within one week, maybe two if needed, but definitely as soon as possible. Please start your bid with the code “s72h&i” so I can filter out the bots. Thank you.
