I need to have a possibility to send sms form different users with different phone numbers. Support Team recommended me setup connection from different users. The app I`m creating is integration between RingCentral and Salesforce.
I created another test account, made the same in there and it works. In this account I got the error but all credentials are correct. I am using password from service as required.
