Abstract: Examples of the present disclosure describe systems and methods for command input using robust input parameters. In an example, a collaborative communication service may provide one or more commands that may be used to perform actions, retrieve information, or access other functionality. A user may use a command by providing an input comprising a trigger. Based on the trigger, a command may be identified, wherein the command may comprise one or more parameters. An input field may be generated for a parameter of the command, such that a user may enter information for the parameter. Once user input has been received, the received input may be validated according to validation logic associated with the parameter. If validation is successful, user input for a subsequent parameter may be requested, or the command may be submitted for processing. Ultimately, a processing result may be determined based on received user input.
