Hi Mate, how it is going?
MY EXPERIENCE IN EBAY APPLICATION DEVELOPMENT:
I am an ebay developer and well aware of ebay APIs(GetOrder Trending API in your case) as i have built 3 ebay enterprise applications which are as follows-
* ALL THESE 3 APPLICATION IMPORT ORDERS, SELLER DASHBOARD, MONTHLY REPORTS, RETURN REPORTS, INVOICES, BUYER MESSAGES ETC FROM EBAY USING DIFFERENT EBAY APIS.
1. Automatic tracking numbers upload application- It reads the gmail account pull the tracking numbers from suppliers emails & upload it to respective ebay order in real time.I can show you demo on dev server. It is similar to [login to view URL]
2. ebay profit loss calculator application similar to [login to view URL]
3. ebay repricing and auto listing application similar to [login to view URL]
UNDERSTANDING OF YOUR PROJECT:
You have not describe what data you want to import to perform your analysis but i am assuming that you want to import ebay statistical data like sales, top rated discount, total return, total disputes, fee fvf fee, paypal fee, ebay listing fee etc etc... so that you can perform data analysis and grow your ebay drop shipping business.
The other part of the application is related to updating the ebay active listings, i am assuming the price and inventory needs to be updated, i need details from you as you have not describe much in project description.
1. I will build an ebay application that will run on your server
2. You ebay store will be linked with this application
3. I will create an auto import script and set it to run automatically every 15 minutes
4. So in every 15 minutes this script will import orders, sales, reports, invoce, returns, etc etc whatever the information you want to import from ebay for your data analysis. However, you need to tell me what are the set of information you want to import then i will tell you if it is possible or not, i have got excellent experience of almost all ebay APIs so i know what is possible and what is not.
5. I will write another web service that will run every 15 minutes automatically and will update your lisings, however, you need to share with me what needs to be updated on listing and i will see what is possible of what is not.
1. Do you want me to work on ebay live account or you have already setup ebay sandbox?
2. Do you want to make an application where you can manage everything in the user dashboard or you just need generic code that does above work?
3. eBay APIs work differently in each country so your store is on .us or .com ebay site?
4. eBay API call limit is 5000 everyday, do you think it is enough or your call can be more that 5000 everyday?
Let's chat and discuss in detail and let me first give you the demo of the exactly same same ebay application that i have build. It calculates the base profit of every ebay sale, that includes everything FVF fee, listing fee, paypal fee, supplier price, ebay price, ebay shipping, ebay tax, top rated discount etc etc...All this information comes form various ebay APIs that i have integrated.
