Send a guided-control packet (highlight / scroll / form-fill)
Broadcasts an agent-initiated control packet into the co-browse data room, after validating the target selector (and, for form-fill, the input type) against the tenant’s cobrowse_privacy policy. A packet targeting a blocked selector, an always-blocked region, or a password-type input is rejected with 403 and audit-logged — this hard floor cannot be relaxed by tenant config. Requires the visitor to have granted control on this session.

Headers
Stripe-style idempotency token. Pass a stable, client-generated value (1-255 chars) to dedupe retries on transient timeouts. The same key+credential+path replays the original response for 24h on 2xx (5min on 4xx, 30s on 5xx). Returns 409 if a concurrent request with the same key is already in flight; replayed responses include the Idempotency-Replay: true response header.
1 - 255Sandbox opt-in for Clerk-session-authenticated requests. Set to true to route the call through the test-mode pipeline: no real provider delivery, no credits deducted, response meta.test_mode: true. Ignored for live API keys (dv_live_sk_*) — server-to-server clients must use a test-prefixed key (dv_test_sk_*) to exercise sandbox. Test-prefixed keys unconditionally enable sandbox regardless of this header.
true, false Path Parameters
Body
What the visitor's browser renders. Only form_fill writes a value into the page.
highlight, scroll, form_fill CSS selector of the DOM node the packet targets. Refused with COBROWSE_CONTROL_BLOCKED when it falls inside a privacy-blocked region.
Type of the targeted input (form_fill only), so the password hard floor is enforced even when the selector carries no attribute hint.
Text to write into the visitor's field. Sent for form_fill only; ignored for highlight and scroll.
Response
Successful response.
