I assume you're using cUrl over a secure connection to send them stuff? At least got the secure connection part nailed? OK, good. I've found that Authorize.net is pretty solid, so if you're getting "incorrect login id or password", it's probably a good guess that that is exactly what the problem is. What you'll probably find is that anyone doing custom work (which this sounds like) is using the AIM method. Can you send us your code? (with the UN/PW/merchant ID replaced with #'s or something similar, of course) Otherwise, you would be best served by searching Google for cUrl tutorials as a starting point. http://www.johnconde.net/blog/tutorial-integrating-the-authorizenet- aim-api-with-php/ Hmmmm... 5th link on a Google search for "sending information to authorize.net via aim" As I said, please feel free to send us over some code to troubleshoot. -- Joe On Sep 11, 2008, at 12:47 PM, Reji Jayan wrote: > Hello all, > > i am asked this type of question by a friend of mine ... since i > dont have any idea about this i am forwarding this here .. > expecting fast reply > > > > the query is on how to connect to authorize.net > > there are some methods like AIM and SIM methods in this/.. for > doing the payment.its same as paypal..but the coder work is some > what different. > We need to give login id and transaction key of the owner to > connect to the authorize.net for online shopping. > where as in pay pal we give the owners email id to connect to paypal. > > so i need some assistance for connecting to authorize.net > please ask for sample code which has successfully connected to the > authorize.net > > and how to give the login id, transaction key..in the source code.. > > i got the sample code from authorize.net but it doesnot connect to > the site..its showing error "incorrect login id or password". > > > Reji. > > Connect with friends all over the world.
