It's already a little late to do what you ask.
I uninstalled the Hikashop component,
I bought the component: Buy Points With Cryptocurrencies: Bitcoin Ethereum, Litecoin, with the aim of testing it independently from Hikashop.
But throw the same problem, does not update the status of the purchase of points.
I installed joomla from scratch to test it independently of my template, and other components that could have some conflict and still does not work.
I verified that coinbase could connect correctly with my site and connects without problems, however I can not find the reason of the problem.
I hope you can help me because I have time limit to present the work.
I wrote another topic in the forum and I attached the images of what is happening, can you check it please ?:
