Apply permission keys to the Web Service Component document to control who has access to use it.
Read access should only be given to users that are allowed to call the functions. For example, if a "purpose built" function has been developed to accept input from a specific source (ie. a third party application), then setup a dedicated Formbird account for the external integration system and provide it alone with access to this Web Service Component document.
Refer to the
Applying Security Keys section of the documentation on how to achieve this.
