I hit the API using Postman
I can get tweets for a single user without any problems.
If i specify multiple users"code": 32, "message": "Could not authenticate you."Will come out.

The URL is percent encoded.
(&→% 2C)
User_name of the tweet I want to get
・ Aaaa123
・ Xxx0000
Will be.

I want to get a list of tweets from multiple users.
Thank you.
