"Failed to validate oauth signature and token" when acquiring a request_token

[episod]

I’m not aware of what Fidder does or does not do, but it’s possible it’s invalidating your request in other ways. A web console like that isn’t the best way to test the API nor the token negotiation methods.

Also, in your request for a request token there, you’re including an oauth_token – oauth_tokens aren’t a valid parameter for the request token step.

The issue is encountered directly from the Fiddler client or in our own code.

The oauth_token was inserted in the header request using your oauth tool. If its not required why does your tool insert?

[episod]

The OAuth tool’s purpose is mainly to address resource API requests – it has less practicality for the OAuth authorization scenario. It’s not aware of which paths mean what, it simply takes the variables you provide to it and builds what a technically valid request would look like given those parameters.

The reason an oauth_token is accepted for oauth/request_token is because it’s a method without a pre-existing context – there’s no access token (no user making the request) and there’s no request token (you’re asking for that).

Hi, I have a “NETWORK_ERR: XMLHttpRequest Exception 101” on this request :

http://api.twitter.com/oauth/request_token?oauth_consumer_key=vMTuvpBlvhEHBd4zhAw7wA&oauth_nonce=qjp8l&oauth_signature=4cQ1rwgLXBkZHT9VAxIX7ir%2BB%2Bk%3D&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1350405504

When I put it into the browser, I get a “Failed to validate oauth signature and token”.
But it was working before…
For what I can see, the query is well formatted, isn’t it ?
Any idea ?

[episod]

You’re missing an oauth_version parameer there it looks like. You’ll find better results using HTTP headers instead of query string parameters.

You should also never use XMLHttpRequest for any steps of the OAuth process. It’s a server-to-server operation.

I have the same problem with him in the.net environment but I haven’t found how to change because I.net also is not very understanding, there’s no such examples, can you give me a reference, it will thank you very much

[episod]

Check out these examples of using the .NET library LINQ to Twitter: http://linqtotwitter.codeplex.com/wikipage?title=Making%20API%20Calls&referringTitle=Home

I am having the same problem, using this PHP SDK: https://github.com/abraham/twitteroauth
this is my url:
https://api.twitter.com/oauth/request_token?oauth_callback=http%3A%2F%2Flocalhost%2Fsparkmetricspro%2Fprojects%2FgetTwitterToken&oauth_consumer_key=gCSfhVwDhO4tzUhvGKgeVQ&oauth_nonce=7396c7c9e04225adbba95e3224481e96&oauth_signature=bq9%2Fm7e542SKrxn3urS72oK%2BChI%3D&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1371567893&oauth_version=1.0

[BluePandaSDA]

Hi did you resolve this issue? I’m getting same problem

[brianjaputra]

Same problem here. I have tried many things, from using abraham and codebird library, built similar library from zero, even used OAuth tool from Twitter application so I can test to execute cUrl generated from Twitter ITSELF. And the result is still same. I wonder what’s wrong with this API.

[Santu_Clabs]

Did u solve this?

[shafiq]

I was also getting same error and spent few hours to figure it out. One extra space was added in the beginning of CONSUMER_SECRET Code while copying it from dev.twitter.com.

That was some silly mistake that wasted my precious time. Hope it’ll help someone.

Hello, even if this is a quite old thread, i am stuck on a very similar problem.
I do use the twitcurl API (with libcurl, libssh2, openssl) and the provided example application TwitterClient do have problems in requesting the following:
https://api.twitter.com/oauth/request_token

Authorization: OAuth oauth_consumer_key=“rm8eGW26CLqGUJnEoXJkbag6m”,oauth_nonce=“1401750717128”,oauth_signature=“JIOdZZJ7dt9kKMlW6n7DS8mvSJw%3d”,oauth_signature_method=“HMAC-SHA1”,oauth_timestamp=“1401750717”,oauth_version=“1.0”

The answer is error code 401: Failed to validate oauth signature and token
The CustomerKey and CustomerSecret are correct, and the HMAC(EVP_sha1(),… , base64_encode(… and urlencode(… of the oauth_signature works properly.
The content of the oauth_signature which get crypted with he secret key is following:

GET&https%3a%2f%2fapi.twitter.com%2foauth%2frequest_token&oauth_consumer_key%3drm8eGW26CLqGUJnEoXJkbag6m%26oauth_nonce%3d140175102412b%26oauth_signature_method%3dHMAC-SHA1%26oauth_timestamp%3d1401751024%26oauth_version%3d1.0

Is it correct that way?
Any ideas?

Thanks

[azamalvi]

I figured it out and found the solution.
It is due to session. When we first send call to twitter and we login form twitter then it sets the session variables. After same time we again login then this error comes. Solution is only destroy the session then again do that this time error will not come.

Hope this will help

I am having same trouble using this PHP library: https://github.com/abraham/twitteroauth by @abraham.

I tested this library on my domain and is working, but on aws company server don’t working.

I found that a possible solution could be, setup properly the server clock. I checked server clock and is wrong, but for any reason, we must not change that.

http://www.blainegarrett.com/2009/07/14/failed-to-validate-oauth-signature-and-token-on-twitter-oauth-check-your-cloc/

Any idea?

[andypiper]

Unfortunately if it is a timing issue, then you’d have to ensure your clock is correct as PHP runs server side.
