Cant Get Frub - signature failed

[A Meidan]

Hi,

I'm trying to get a frub, and get an error stating "Invalid
Signature" .
This is my java code for generating the MD5:

String strToDigest = sharedSecret+"api_key"+API_KEY;
MessageDigest md5 = MessageDigest.getInstance("MD5");

byte[] msgToDigest = strToDigest.getBytes("UTF-8");
byte[] sigBytes = md5.digest(msgToDigest);

api_sig = new BigInteger(1,sigBytes).toString(16);

Please Help.
Thanks.

The string to digest should also include the method (and format if you are using that parameter).

for example: SHAREDSECRETapi_keyAPIKEYformatjsonmethodrtm.auth.getFrob

I built a tool called milkapi.com to help with using the RTM API which may help you as well.

Thanks,
I'm doing it for educational purpose, so I'm cool with getting my
hands dirty. :)

Another question, if you don't mind,
When do i need to do the authentication sequence? each request? only
when logging in?

Thanks.

Once you acquire the auth token via the authentication sequence, you just use the auth token for all further requests.
