Partially update ONE guard rule

Updates only the fields you send. Common uses: toggle is_active to disable a guard temporarily; add a channel to selected_channels; tighten when_condition text after testing. Switching then_action between forward and end_conversation is supported but make sure the corresponding destination/say_before_* fields are set.

Authorizations

Authorization · string · header · required

Use a Bearer token to access these API endpoints. Example: "Bearer {your-token}"

Path Parameters

uuid · string<uuid> · required

ruleUuid · string<uuid> · required

Body

application/json

Guard rules let the agent forward or end a conversation when a defined situation arises (compliance, safety, escalation). The runtime AI relies on when_condition and example_phrases to decide whether a customer utterance triggers the guard — rules without those fields filled cannot fire reliably.

name · string | null

Optional short name for the guard rule.

Example:

"Legal complaint escalation"

when_condition · string

Required. Natural-language description of the situation that should trigger this guard. The runtime AI uses this as instructions when classifying customer utterances. Be specific — 'customer is angry' is too vague; 'customer uses profanity or threatens to escalate' is actionable.

Example:

"Customer mentions a legal complaint, lawyer, lawsuit, or threatens to take legal action."

example_phrases · string[]

Customer utterances that should trigger this guard. Provide 3-5 varied phrasings — the runtime AI uses these as positive examples when classifying.

then_action · enum<string>

What the runtime agent does when the guard fires. forward transfers to a human or another agent; end_conversation politely ends the call/chat.

Available options: forward, end_conversation

Example:

"forward"

selected_channels · enum<string>[]

Channels where this guard is active. Defaults to phone-only.

Available options: phone, instagram, whatsapp, facebook_messenger

say_before_forwarding · string | null

Message spoken before the transfer when then_action=forward.

Example:

"I understand this is important — let me connect you with someone who can help."

say_before_end · string | null

Message spoken before ending when then_action=end_conversation.

Example:

"I'm sorry I couldn't help further. Please contact our team directly. Goodbye."

destination_type · enum<string> | null

Where the call is sent when then_action=forward (same semantics as routing rules).

Available options: extension, phone, agent

destination · string | null

Destination value (extension, SIP URI, or E.164 phone) when then_action=forward.

destination_agent_uuid · string<uuid> | null

Target agent UUID when destination_type=agent.

is_active · boolean

Example:

true

is_default · boolean

Marks this guard as a default that auto-applies to new agents in the workspace.

Example:

false
