I want to know how we can call an external service from Sitecore and include the retrieved data from its response into the layout service using JSS.
We manage the core Product data in Sitecore and also build a micro service to serve the frequently updated data such as Price. So, we would like Sitecore to call our micro service to retrieve the product price data and then show it in front-end along with other product data stored in Sitecore.
Could you please advise me on the right approach using Sitecore JSS?
