In Customer Portal (CP) versions 3.8 and lower there is a 'valid_file_extensions' attribute in the ChatAttachFileButton widget where you can define a list of accepted file extensions without leading periods and separated by commas. CP 3.9 and greater uses the CP.ValidFileExtensions and CP.ValidFileMimeTypes values set in siteConfig.json instead.

Please note, the 'valid_file_extensions' default for the attribute is defined by all extensions.

You can edit this widget by going to the path below:

Customer Portal v3.x (3.8 and lower):

standard/chat/ChatAttachFileButton

Example:
<rn:widget path="chat/ChatAttachFileButton" valid_file_extensions="gif,pdf,doc" />

 

For customers on CX version 23A+ will also have access to a config verb called VALID_FILE_EXTENSIONS. You will need to make sure that any changes you make to the siteConfig.json (CPv3.9), or 'valid_file_extensions widget (CPv3.8) matches the config verb. If not, then the restrictions will not work.
