Twitter update.json reply to a tweet id result in "could not authenticate 32"

[Nkatkamwar]

GET search.json, POST status update.json works

but POST https://api.twitter.com/1.1/statuses/update.json?status='+'test@testUser+'&in_reply_to_status_id='+56xxxxxxxxxxxxxxx

results in { errors: [ { message: 'Could not authenticate you', code: 32 } ] }

Can somebody tell me where am I wrong ?

What HTTP response code are you getting? Take a look at the docs on error response codes as that may help you to debug this.

response code is 200 OK . I am trying multiple ways but still it would not authenticate me. I dont know where am I going wrong …
