🔗 URL Parameters

In Open WebUI, chat sessions can be customized through various URL parameters. These parameters allow you to set specific configurations, enable features, and define model settings on a per-chat basis. This approach provides flexibility and control over individual chat sessions directly from the URL.

The following table lists the available URL parameters, their function, and example usage.

web-search	Enables web search functionality if set to true.	/?web-search=true
tools or tool-ids	Specifies a comma-separated list of tool IDs to activate in the chat.	/?tools=tool1,tool2
call	Enables a call overlay if set to true.	/?call=true
q	Sets an initial query or prompt for the chat.	/?q=Hello%20there
temporary-chat	Marks the chat as temporary if set to true, for one-time sessions.	/?temporary-chat=true

• How to Set: Provide a comma-separated list of tool IDs as the parameter’s value.
• Example: /?tools=tool1,tool2 or /?tool-ids=tool1,tool2
• Behavior: Each tool ID is matched and activated within the session for user interaction.

• Example: /?temporary-chat=true
• Behavior: This initiates a disposable chat session without saving history or applying advanced configurations.

Example Use Case

Temporary Chat Session

Suppose a user wants to initiate a quick chat session without saving the history. They can do so by setting temporary-chat=true in the URL. This provides a disposable chat environment ideal for one-time interactions.

Using Multiple Parameters Together

These URL parameters can be combined to create highly customized chat sessions. For example:

/chat?models=model1,model2&youtube=VIDEO_ID&web-search=true&tools=tool1,tool2&call=true&q=Hello%20there&temporary-chat=true

This URL will:

• Initialize the chat with model1 and model2.
• Enable YouTube transcription, web search, and specified tools.
• Display a call overlay.
• Set an initial prompt of "Hello there."
• Mark the chat as temporary, avoiding any history saving.
