Update channel settings by a custom channel type

custom_type

string

Specifies the custom channel type.

display_past_message

For example, if the value of user_messages_per_channel is set to 7 and the value of user_messages_per_channel_duration is set to 3, a user can send seven messages in three seconds and any messages beyond the seventh one will be blocked. (Default: 1)

domain_filter

nested object

A domain filter configuration to filter out text and file messages with URLs that contain the domain set.

domain_filter.domains[]

array of strings

Specifies an array of domains to detect. Each item of the array should be specified in a combination of domain name and TLD (top level domain) like amazon.com.

domain_filter.type

integer

Determines which filter to apply to messages with URLs that contain 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 (*).

profanity_filter

nested object

A filter configuration on certain words and patterns for matching character combinations in strings, which are not allowed to be used within the application.

-*word filters all words that end with "word" including "word" itself.
- word* filters all words that start with "word" including "word" itself.

profanity_filter.regex_filters[]

array of strings

Specifies an array of regular expressions used for detecting. Each item of the list should be specified in {"regex": "a pattern in regular expression"}format.

profanity_filter.type

integer

Determines which filtering method to apply to messages that contain the specified keywords or regular expressions. Acceptable values are the following.
- 0 (none): Takes no action on matched messages. This is the default value.
- 1 (replace): Detects and replaces words that match the keywords property with asterisks (*).
- 2 (block): Prevents users from sending messages that contain the keywords property or match the regex_filters property.

profanity_triggered_moderation

nested object

A moderation configuration on which penalty is automatically imposed on users who reach the profanity violation limit within a channel.

profanity_triggered_moderation.count

integer

Specifies the number of profanity violation limit before a penalty is imposed on a user.
- A value of 0 indicates that automatically-triggered moderation is turned off.
- A value of greater than or equal to 1 indicates that the moderation is turned on and imposes a penalty on a user who commits a number of violations equal to or beyond the set value of the count property within the set time of the duration property. (Default: 0)

profanity_triggered_moderation.duration

integer

Specifies the duration of the time window in seconds which counts the number of a user’s violations within a channel. For example, if the count property is set to 2 and the duration property is set to 5, the number of violations equal to or beyond two will be moderated for every five seconds. The maximum value is 86400 which indicates 24 hours. (Default: 1 second)

profanity_triggered_moderation.action

integer

Determines the type of moderation penalty within a channel which is permanently imposed on users until canceled. Acceptable values are 0 (no action), 1 (mute), 2 (kick), and 3 (ban). (Default: 0)

image_moderation

nested object

A moderation configuration on inappropriate images in the application. Google Cloud Vision API is used for image moderation and supports many types of images.

image_moderation.type

integer

Determines the moderation method to apply to the images and image URLs in the text and file messages. Acceptable values are the following.
- 0 (none): No moderation is imposed. This is the default setting.
- 1 (normal): The messages with images or image URLs are blocked if the images or image URLs violate the content policies.
- 2 (strict): The file messages with no images are also blocked in addition to the messages with explicit images or inappropriate image URLs.

image_moderation.soft_block

boolean

If true, the moderation method set by the type property above is ignored and no moderation is imposed on the text and file messages in regard to explicit images or inappropriate image URLs. It will only give the image analysis results in the response. If set to false, the image moderation works according to the moderation method already set.

image_moderation.limits

nested object

A set of values returned after an image has been moderated. These limit numbers range from one to five and specify the likelihood of the image passing the moderation standard. Acceptable likelihood values are 0 (unknown), 1 (very unlikely), 2 (unlikely), 3 (possible), 4 (likely), and 5 (very likely).

image_moderation.limits.adult

integer

Specifies the likelihood of the image containing an adult content.

image_moderation.limits.medical

integer

Specifies the likelihood of the image being a medical image.

image_moderation.limits.violence

integer
