Errors when requesting an OAuth token

Hello,

I am the lead developer at a premium WordPress plugin development agency, and we're currently working on an integration with BitBucket. The first problem, however, is that I am unable to even request a token so that the user can authenticate access to their BitBucket account. This is the url that I am attempting to browse to:

https://bitbucket.org/api/1.0/oauth/request_token?oauth_version=1.0&oauth_nonce=d799ffdce7ffaa13f8239a406875e081&oauth_timestamp=

{timestamp}

&oauth_consumer_key=

{key}

&oauth_signature_method=HMAC-SHA1&oauth_signature=

{secret}

&oauth_callback=http%3A%2F%2Flocalhost%2Ftest%2F

The url was generated using the testing site recommended on the BitBucket documentation page here: https://confluence.atlassian.com/display/BITBUCKET/OAuth+on+bitbucket

It's also worth pointing out that the testing site recommended on the document listed above doesn't allow requesting an initial request token, because it doesn't send an oauth_callback parameter. Therefore, the BitBucket API just returns an error every time you attempt to use it.

I have tried every permutation of the url above that I can think of, using PLAINTEXT, generating a new APP with new keys/secrets, generating new timestamps. Nothing has worked.

My goal with this plugin is to allow users to download tags as zip files from private and public repos. I'm thinking that I can do something like:

https://bitbucket.org/

{user}

/

{repo}

/get/

{branch,tag}

.

{zip,tar.gz,tar.bz}

and pass the authentaicated OAuth token as a parameter to access the zip file.

We have been working on this integration for a few weeks, and we would like to get this plugin into the hands of our users as quickly as possible.

Thank you very much for the time.
