I've gone in to Notification Delivery and selected usa.bulksms.com in the predefined list and entered my account info below with username and password and account ID. I've then in the Notifications section clicked on my object and made the Send to Number field my group ID on Bulk SMS. After all of this i still get an error in the Logs saying
|"Error sending "SMS": Number=241508, Message=Password is wrong."
I've also tried the custom URL that some articles mention substituting the ** for the actual username and password and but still have had no luck.
Any one able to help me out with this or point me to a step by step tutorial. I'm at a complete loss right now.
