  1. Define the variables in the Contexts view in the Studio workspace following the pattern parameter_<parameter_name>, all in lower case, where:


    fixed prefix

    If you do not use the parameter_ prefix, the parameter will appear in the Advanced parameters section of the task creation wizard instead of the Parameters section after the artifact is published to Talend Cloud Management Console. The use of this prefix is not compulsory, it just changes the placement of the parameters in the app.


    name of the parameter

    Use underscore to separate words in the parameter name if necessary.

  2. When you publish the artifact with the user-defined parameters to the Cloud, parameters fields are displayed and labeled with the parameter names you defined in the Studio, allowing the web user to set/change parameter values at runtime.
    For further information, see Setting user-defined parameters.
    For examples of context parameters, import the Talend Cloud Demos project to your Studio.
