Suppressions are recipient email addresses that are added to unsubscribe groups. Once a recipient's address is on the suppressions list for an unsubscribe group, they will not receive any emails that are tagged with that unsubscribe group.
This endpoint allows you to add email addresses to an unsubscribe group.
If you attempt to add suppressions to a group that has been deleted or does not exist, the suppressions will be added to the global suppressions list.
Bearer <<YOUR_API_KEY_HERE>>The on-behalf-of header allows you to make API calls from a parent account on behalf of the parent's Subusers or customer accounts. You will use the parent account's API key when using this header. When making a call on behalf of a customer account, the property value should be "account-id" followed by the customer account's ID (e.g., on-behalf-of: account-id <account-id>). When making a call on behalf of a Subuser, the property value should be the Subuser's username (e.g., on-behalf-of: <subuser-username>). See On Behalf Of for more information.
