Activate a Knowledge base version

POST /v1/knowledge-bases/{knowledge_base_id}/versions/{version}/activate

Property	Value
Operation	`activate_knowledge_base_version`
Group	Knowledge bases
Scope	`knowledge:write`
Route class	`control`
Idempotency	`Idempotency-Key` accepted: a retry with the same key replays the first answer
Audit	Audited `knowledge.version.activate` (mutation)
Released in	1.53.0
Phase 0 host	Served (the hosted api pins 1.65.0)

Makes the version the active one and answers it (1.53.0): bindings that track active resolve it from the next dispatch, and Calls in progress keep the version they resolved. Activating an older version is the rollback. A retired version is refused with 409 knowledge_base_version_retired.

Request

Set VOCAL_API to the base URL of your API and VOCAL_API_KEY to an API key with the knowledge:write scope (Authentication and keys). Replace each placeholder, such as agt_... or <name>, with your own value.

curl -X POST "$VOCAL_API/v1/knowledge-bases/kb_.../versions/1/activate" \
  -H "Authorization: Bearer $VOCAL_API_KEY" \
  -H "Idempotency-Key: $(uuidgen)"

const response = await fetch(`${process.env.VOCAL_API}/v1/knowledge-bases/kb_.../versions/1/activate`, {
  method: 'POST',
  headers: {
    Authorization: `Bearer ${process.env.VOCAL_API_KEY}`,
    'Idempotency-Key': crypto.randomUUID(),
  },
});
console.log(response.status, await response.text());
