Could not authenticate you Postman

[ivbojic]

Hello. I’m calling GET users/show api from Postman and cannot pass authentication.

Steps taken:

1. Create a developer app.
   a. Set Website url, do not enable sign in with twitter (i.e. no call back url)
   b. Generate keys and tokens (2 consumer api and 2 access)
   c. Set permission to read and write
2. In postman
   a. set authorization data to “Request Headers”, copy the 4 keys and tokens
   b. send GET request https://api.twitter.com/1.1/users/show.json?screen_name=ivbojic

This resulted in code 32: Could not authenticate you.

3. Go back to developer app
   a. enable sign in with Twitter
   b. add call back url
   c. change access presmission to Read, write, and direct messages
   d. Re-generate keys and tokens (2 consumer api and 2 access)

4. In Postman
   a. update the re-generated keys
   b. send GET request

Still cannot pass the authentication:
Error code 32: Could not authenticate you.

Note: signature,timestamp, nonce,version and realm are autogenerated generated by postman for empty values

Any idea what am I missing?

Thanks
