Deprecated. Project Constants are no longer available to new customers. This feature has been replaced by Conversation Variables, which provide the same static value reuse with additional support for dynamic values and cross-culture usage.
What were Project Constants?
Project Constants allowed you to define a list of named static values at the project level — for example, a phone number, product name, or URL — and reference them inside article answers. If the value changed, you only needed to update the constant in one place rather than editing every answer that used it.
Migration
Conversation Variables replace Project Constants entirely. A conversation variable with a default value behaves identically to a project constant. To migrate:
-
Go to Configuration > Conversation Variables and recreate each constant as a conversation variable with the same name and default value.
-
Replace the constant references in your article answers with the corresponding conversation variable.
-
Publish the project.
See Guide to Conversation Variables for step-by-step instructions.
