}Interactions
Create Interactions Bulk
Record up to 1000 interactions in one call — for backfilling history.
Each interaction is enriched (reward_value, feature_uri/context promotion)
exactly like the single-create path, then written. Reward config is resolved
ONCE per distinct retriever (not per interaction). Dedup and the real-time
session cache are skipped — bulk writes are for historical backfill, not
live in-session adaptation. Set each interaction’s occurred_at to its
true timestamp so temporal decay weights it by real age.

}Authorizations
Mixpeek API key, sent as Authorization: Bearer mxp_sk_.... Create one in Studio under Settings → API Keys, or with an admin key via POST /v1/organizations/users/{user_email}/api-keys. A missing, malformed, unknown, revoked, inactive or expired key returns 401; a key without the permission, scope or plan an operation needs returns 403.
Namespace id (ns_...), not the namespace name. This scopes the request rather than authenticating it, and it is required on every operation marked x-mixpeek-namespace-scoped.
Body
application/json
Keys this body does not declare are refused with 422 extra_forbidden naming the accepted keys (since 2026-11-02).
Record many interactions in one call — for backfilling historical logs.
The intended use is migrating an existing click/purchase history into
Mixpeek: send the interactions in chunks (≤ 1000 per call) with each one's
occurred_at set to its true timestamp, so learned-fusion temporal decay
weights them correctly. Backfilled events bypass the real-time session cache.
Interactions to record (1-1000). For historical backfill, set each interaction's occurred_at to its true time.
Required array length:
1 - 1000 elementsShow child attributes

Response
Successful Response
Result of a bulk interaction write.
Number of interactions accepted for write.
Number that could not be processed (see errors).
Per-interaction error messages (indexed), if any failed.
Per-item results with assigned interaction IDs.
