DELETE/v1/conversations/{conversation_id}/tagsbeta

Untag a conversation

Needs: Manage conversations: notes, assign, close, tags, reminders (inbox:write)
Plan: Any plan with API access
Limits: 60 a minute per key
Dry run: Yes — every check runs with ?dry_run=true, nothing changes
Undo: Add them back with Tag a conversation.

Removes tags from a conversation, by id and/or name, given as query parameters (repeat one for several: ?tag_ids=4&tag_ids=7). Tags the conversation does not have are ignored, so a retry is harmless. The tags themselves stay in the workspace.

Try it

Path

conversation_idrequiredstring

The conversation id.

Query (2)

tag_idsoptionallist

Conversation tag ids to remove.

tag_namesoptionallist

Tag names to remove.

Idempotency-Keyoptional — made for you if empty

Protects against doing it twice if you retry: a retry with the same key gets the first answer back instead of running again.

Test mode (dry run): nothing will change

Run liveTurns test mode off for this page only. It switches back when you leave the page.

curl -X DELETE 'https://mcp.wa-api.cloud/v1/conversations/77410/tags?tag_ids=7&dry_run=true' \
  -H "Authorization: Bearer $API_KEY" \
  -H "Idempotency-Key: $(uuidgen)"

The code reads your key from $API_KEY.

Errors

Errors are application/problem+json. Branch on code.

Status	Code	When
400	invalid_input	A field is missing or has the wrong format. `errors[]` points at each field. Neither `tag_ids` nor `tag_names` was given (up to 20 each).
401	unauthenticated	The Authorization header is missing, the key is unknown, expired or revoked.
403	entitlement_required	The workspace's plan does not include API access (`api_access`).
403	insufficient_scope	The key does not have the permission this operation needs.
404	not_found	No conversation with this id.
409	conflict	Also returned while a request with the same Idempotency-Key is still running.
429	rate_limited	The key or workspace went over its rate limit. Wait for `Retry-After` seconds.
503	upstream_unavailable	A service behind the API is briefly unavailable. Safe to retry with backoff.
504	timeout	The change did not finish in time. Retry with the same Idempotency-Key: it never runs twice.
