How to display attribute value label instead of numeric value on response of /V1/products/:sku and /V1/products/?searchCriteria?

Question

I have one multi-select attribute(filter_cuff). Its value is Single Button Cuff,Two Button Cuff,Single Button Rounded,Double Button Rounded. When I call /v1/products/:sku API, it shows response like:

custom-attributes{"attribute-code":"filter_cuff","value":"20"}

I want to show its value i.e. Single Button Rounded instead of 20. How can it possible?

Please Help me.
