I have followed the steps required to create a new application and getting consumer key, secret pairs and also the token access details. Now I would like to make calls to Tw
Apart from the authentication settings that are taken from twitter developer console, when searching q=target_user_id it worked as opposed from q=@target_user_id, where I got the error 32, could not authenticate you.
So, after numerous attempts, what made a difference was just removing the "@" symbol from the q parameter value.
Postman creates 6 character nonce, Twitter needs 32-character Nonce. So you can use any random value, I used ABCDEFGHIJKLMNOPQRSTUVWXYZ123456 (length=32)
If anyone reaches this in 2017, my problem was the nonce too but the one with length 32 didn't work for me. I checked the tutorial and used the one posted there and it started working. Make sure you choose postman to add the authorization data to the headers and not the body.
This is my working nonce: kYjzVBB8Y0ZFabxSWbWovY3uYSQ2pTgmZeNu2VS4cg
