Yes you can use the headers() field in next.config.js or middleware for this

but that will be for the page, right

[cunning oak]

Nope. It is for everything

[nocturne lance]

Understood!.. can it be possible to set it directly in the /api/route?

[cunning oak]

I think headers() in config should have a way to configure setting certain headers for certain route patterns, while for middleware it is either the matcher or something like if (req.nextUrl.pathname.startsWith("/api"))

Okay!.. I am not pretty sure about how middleware works, so I guess first request will go to middleware then to API and back to middleware, right?

[cunning oak]

Not sure about the “back to middleware” part because I’ve never used middleware that way, but you can test. Otherwise yes, middleware runs first then the api route is run

[nocturne lance]

Okay!.. I am very new to this middleware part
