Hello, i wish to develop an application with a react js based frontend, working with a Laravel php backend/API. At first i was thinking my frontend would call my backend and Shopify's API separately. But what if i want my backend to be able to make the calls to Shopify also? Do i / can i put the same api keys from my partner dashboard in both my react front-end and php backend? Or do i need to generate 2 applications in my dashboard for this? but then, wouldn't customers have 2 applications to install? which i wouldn't want. Any explanation or clarification is appreciated thank you!
