downloading an attachment via Yahoo! Mail API

Obiora4 Jan 2011 5:06 PM

Hello, I am having issues with downloading an attachment via the API for Yahoo! Mail.

I have used several different Oauth libraries and have recently tested code (http://nullinfo.wordpress.com/oauth-yahoo/) for CallContact, which does work.

I am using the data generated from CallContact to download an attachment and the sent header and response are below:

The mid has been encoded and the URL is correct and is based on the documentation. Is there something that I am missing that the documentation does not cover??

Thank you.

great to here, so maybe you can help me out :) I didn't understand what's the solution -  1. did u use an OAuth Authorization header or sent all the oauth parameters in the url? 2. should the signature contains the regular params (mid, fid... ) or just the basic url + oauth parameters? this is my request: http://mail.yahooapis.com/ya/download?clean=0&fid=Inbox&inline=0&mid=1_22_1_4931_0_AIHTimIAAAG0Tmsv5AzWR1FOqEA&pid=2&oauth_consumer_key=..............&oauth_nonce=8016381357093189350&oauth_signature=EcZSH5%2B6ny6U%2BHWAmLgWG9RXQlk%3D&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1316881005&oauth_token=A%3DkOSQRMrSmwPrWniqY02.4qxYoKKD61EIL19M9uDuBvRBbtxCiRVx7jJum3cV6ebWNdM0zDF7sU2ezKPa2Y6cT9ZJIlazRBkxhasb_l1n3I_DmRY48drpYDMB2g4IEPZF355iOQ7FGIJaxTCT6E1nJSlmgqbx7zmrJHOe43qiyhWWSVNOLzVWUjAWdTUYN4jJ3hodR1o.55sbHlBIdq.L.lmR5D4VS7tBbqg7mt9t9gclib3s17JNwmvX.8s7OJRQ5fZMBbxWaTKytcnl_DaNlUAljYX6yEbaxkTmOMB7fNrEFeexklpNfAlTy8.rmVAddLh8J0vI12hNYYuuPRRXzMrSgDoDV27x1AsiMDt1fJWj43Sd3NPvmmwCCXwxwCXn0ad_1h.YJPUqyJxEwxuYFK85XdrHpfeULgwth6Fukh7PaC5v9jvQOQR9p_wDIHJKuBFcmZkjlp7h1ID0Y08WbdMotaX1qMkbPmMvPhX7AV8VfasFxj3vo3.MVmc6ndWLPAXX0ep6EkNrpBZadI6tK_5a213QvRPlZcneCcdXWJWD5BpyDrMXdyVdMMC5bB6jQ0jBEN9GmxbMuvt9Xo0N8IlKLJII7jfmZZpPjC8V8HklHbpOOQaDsGU1muDdNAgPKi6qp53ZH5.TuUd7X3C_51pvPC0uopJaAs7SE9XBEVjCNeEZ9jkbJuRoUgTkoBcZTNa6PJXH7j9q5NZ4KTiL2z2Kjq_3fPrO3U0plPn7cF.T0UmqLwhtZisL1HouwQ--&oauth_version=1.0 I keep getting 404 Not Found for that request.  If I drop the mid,fid.. params I get "500 unable_to_get_message_info_or_part". other calls to the Yahoo mail web services are working just fine with the oauth mechanism... any ideas? thank a lot, Asi. <div class="quote "><div class="quotetop ">QUOTE<cite>(Obiora @ 23 Sep 2011 5:09 PM)</cite><blockquote class="quotemain">Yes, I did resolve the problem.
