How to open sales statistics by promo code

[mixfaq]

Good day everyone

I'm starting work with shopify, I have a question about development. One of the stages of promotion is posts from bloggers. The blogger posts a post with a link to my store and gives customers a promo code. How can I share promo code usage statistics with a blogger?

Best regards, Nikita

P.S. It is important that this is not a screenshot or something like that. A blogger must understand that I am honest with him and do not hide sales from him through his advertising.
