Hello there, I've been reading that you're wanting to have a solution to take the sales data of your existing sales from Ebay API and save the same to sql.
I do have over 7 years of experience with specific expertise working with ebay API as well as sql and shall therefore be glad to have this opportunity of working with you and build that you need done.
Particularly, you're wanting to have from old till the newest sales data be stored to Sql tables and have the script run on regular interval such as 5 minutes to grab the newest data and store the same.
I'm sure to build the required solution with highest quality and quick turnaround.
What I'll need is the following:
-Access to your ebay API creddentials (using your secret keys and seller ID)
-Any specific field from sales data that you want me to capture or avoid
Please write back and I'll be happy to answer any questions that you may have. Any questions in regards to ebay API, sql, programming language (PHP, .net and java), please let me know and I'll be happy to answer the same.
Looking forward to your response and get started.
