API Security
The API will only work from the IP addresses or IP address ranges specified, and if you have an API password specified in your account. If you do not specify an IP address or IP address range or do not specify an API password, you will not have access to the API.

You can set these IP’s by logging into your account, selecting “Advanced Mode” or "Advanced Mode", and then clicking on “Setup & Options” , then click on “Advanced Settings”. Enter your trusted IP’s in the textbox provided, separated by commas.

If you need to change your API password, you need to contact support.
