OAuth nonce values already used?

Started by David Edwards -   in API Authentication

I'm trying to authenticate a private app using the Zend Framework OAuth classes. So far, I have got my Consumer looking in the right place, and I'm pretty sure I have the correct values for my consumer key/secret and RSA keys, but when trying to get a request token I get the standard nonce_used error in my responses:

"The nonce value "221d1a62562c1efaa8298dad7053d6cc9" has already been used"

(Naturally I get a different nonce each time)

Any hints as to where I'm going wrong?
Sorted my problem! Was failing to construct my own access token from the consumer key and secret. Not sure why that would have resulted in the responses I was getting, but at least I've cleared this particular hurdle.
