    Copy link

    The domain filter is designed to detect anything that is seemingly inappropriate in user-submitted messages, images, and more. It allows you to filter out certain domains contained in text and file messages as well as users’ profile images according to your policies and criteria.

    HTTP request

    // To apply the settings application-wide.

    // To apply the filter to channels with a custom channel type.

    Property nameTypeDescription


    nested object

    Specifies a domain filter configuration to filter out text and file messages that contain an URL matching the domain set. This property also filters out a user's profile image URL if it matches the domain set.


    array of objects

    Specifies an array of domains to detect. Each item of the array is specified with a combination of domain name and TLD (Top Level Domain) such as amazon.com.

    * Domain moderation applies only to the message property of a text or file message resource, not the data property or the metaArrays property.



    Determines which filtering mode to apply to messages that contain URLs matching any of the domain set. Acceptable values are the following:
    - 0 (none): takes no action on matching messages. This is the default value.
    - 1 (allow): only allows messages containing URLs that match the domains property.
    - 2 (block): blocks messages containing URLs that match the domains property.
    - 3 (replace): detects and replaces URLs that match the domains property with asterisks.



    Determines whether to apply the domain filter of the application settings to messages in addition to domain_filter of the custom channel type. The default value of the property in the global settings is false. (Default: false)
