Why am I getting an IP Address Not Allowed error message using SOAP?

Environment:

Oracle B2C Service version May 2013 and newer, Connect Web Services for SOAP API

 Resolution:

There are many reasons to get the Access Denied message but because of increased security on Oracle B2C Service version May 2013 and newer, there is a new configuration setting that needs to be set if you are connecting through SOAP API and not having this configuration set will cause the above error. 
Check your SEC_PAPI_INTEG_HOSTS_SOAP setting and add your IP Address, domain names with wildcards or subnet masks (for example, *.rightnow.com,1.2.3.4, 10.11.12.0/255.255.255.0) if applicable.

Default is blank.
