API: HTTP Show Optouts
The Show Optouts command allows you to return all contacts that are opted out of a single list, regardless of origin of the event. The command requires the following arguments: Command, Realm, Password, List ID, and Days.
api_web?r=myrealm&p=mypass&c=show_opt&list_id=5&days=7
The command is ‘show_opt’, the realm is ‘myrealm’, the password is ‘mypass’ and will return optouts that occurred for list_id='5' in the last 7 days.
The command will attempt to find all contact optouts associated with the specified list and return the results. A successful search will return a list of email addresses that have been opted out of the list.
Example
Using all commands and arguments (please note the command is wrapped for display purposes only):
api_web?c=show_opt&r=myrealm&p=mypass&list_id=5&days=30&output_format=csv&headers=1
Successful results return:
"Email"
"jane@mydomain.com"
"john@mydomain.com"
"joe@mydomain.com"
Some systems have the ability to define a unique Customer Key per contact. If your realm has Customer Key enabled, and additional column "customer_key" will be included in the results.
Results
The Show Optout command outputs either the results of the search or a FAILURE message.
SUCCESS
The Show Optout command does not explicitly return a Success code. Instead, it outputs the email address of the contact in plain text format. Use the output_format argument to return the results in an alternate format.
If there are no results matching the request, nothing is returned.
FAILURE
A Show Optout command will fail for several reasons, such as if the list doesn't exist. The result format is:
FAILURE: [Reason]
