How to test the multilingual chatbot integrated to Facebook messenger, Dialogflow always uses English(Default language) when integrated to FB messenger.
I tried to changed the facebook profile settings also, but still it is not recognizing the other languages other than the English.
So, How to test/work with multilingual chatbot in Facebook messenger?
Thanks in Advance.

I´m actually after the same thing, I reached DialogFlow support, and they told me this:
Thanks for reaching out to Dialogflow Support.
At the moment, Dialogflow does not yet support multiple languages for any of its built-in integrations - so requests from Facebook Messenger will automatically only be sent to the Default Language of the agent.
However, you can try to make your own implementation for this. You may consider creating a middleware that would serve as a bridge between your Dialogflow agent and your Facebook Messenger bot.
When a user sends a query from Facebook Messenger, your middleware should detect which language was used and then it should send a detectIntent request (https://cloud.google.com/dialogflow/docs/reference/rest/v2/projects.agent.sessions/detectIntent ) to Dialogflow containing both the query and a "languageCode" parameter field with the language tag (https://cloud.google.com/dialogflow/docs/reference/language ) of the end-user's language. You can use Dialogflow's REST API (https://cloud.google.com/dialogflow/docs/reference/rest/v2-overview ) or client libraries (https://cloud.google.com/dialogflow/docs/reference/libraries/overview ) to integrate your middleware to Dialogflow.
