What is the recommended way for handling a multilingual service? I'm using the Services module together with a multilingual backend (field translation). My endpoint is v1. What I would like to have is &lt;domain&gt;/v1/fr/....

Is this possible without having a redirect?

If you are using the language code as a URL prefix, then you should be able to access your endpoint as usual with the language code prefixed to it:

?q=fr/v1/...


For example, to get a node in French you could make a GET call on:

?q=fr/v1/node/123.json
