Twitter API Postman: Code 32: Could not authenticate you

Question

I want to test the Twitter api for an app in the future. I was trying to test it with Postman but I get this error all the time.

"code": 32, "message": "Could not authenticate you."

I made an new app from my developers account and put all the generated tokens into postman like this:

My parameters are the same like this screenshot: (with the correct tokens)

Do I need to check something important? I hope someone has already faced this problem or just can help me with this.

Solution 1

Under the "Authorization" tab in Postman, choose "Request Headers" from the "Add authorization data to:" drop down.

Useful reference: https://developer.twitter.com/en/docs/basics/authentication/guides/authorizing-a-request.html

Solution 2

Error 32 "Could not authenticate you" can also happen when the content of the tweet triggers the Twitter censorship filter.

Solution 3

For anyone still having issues...

My problem was that the Content-Type: application/x-www-form-urlencoded header was not set for my POST request when testing with Postman. Once I added that, all was well.

Solution 4

Follow the picture and you will get the correct return.

Solution 5

Another thing to check is the ! character in the status that's being posted. Ensure it's encoded correctly.

Thanks for your answer, I accept it because it solved my problem. unfortunately I have the same problem with an other api call. I chose Request Headers, but It gives me again code 32: Could not authenticate you api.twitter.com/1.1/search/tweets.json?q=%23somerandomhashta‌​g

@Peter I have the exact same problem... I'm able to authenticate on the /user_timeline endpoint but not on the /search endpoint. I'm digging in and will update if I can get a solution.

by giving OAuth 1.0, I got answer in postman ,but in localhost it shows "code": 32, "message": "Could not authenticate you." how could i resolve the prolem?

@Miles Did you solve this issue. I only get this error if I add query params to the query. If I hit the end point without any params, all works ok.

[Miles]

@wuf810 Nope. I punted and moved on. I got it working with fetch() in my app. Which is all that really matters I guess.

@wuf810 I had the same problem. For me it was changing the Content-Type: application/x-www-form-urlencoded like ryanulit answered that solved it.

Read every answer here and could not get this to work using Postman. As was the case with @Miles I eventually got it working correctly with Fetch. No idea why.
