The individual records carry no identity of their own: the credential decides the org and user. Duplicate signals are reported as `deduped` rather than stored twice. ## Authorization This route requires the `write` scope. A missing or invalid credential returns 401 [`authentication_error`](/errors/authentication_error). A valid credential without the scope returns 403 [`permission_denied`](/errors/permission_denied), and the problem body names the exact scope required. ## Headers These are request conventions the contract does not declare as parameters, so they do not appear in the schema tables below. | Header | Applies | What it does | | ----------------- | ------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `X-Exo-API-Key` | Required | Your Exo API key, `exo__`. `Authorization: Bearer exo_...` is accepted as an alternate. | | `X-Exo-Subject` | Refused | This route scopes data by the key owner. Sending the header returns 400 [`subject_not_supported`](/errors/subject_not_supported), rather than silently reading the wrong partition. | | `Idempotency-Key` | Not honoured | This route does not replay: signals deduplicate per record. | | `X-Request-Id` | Response | Returned on every response, including `204`s. Quote it in a support request. | ## Success responses | Status | Meaning | | ------ | ---------------------------------------------------------- | | `202` | How many signals were queued and how many were duplicates. | ## Errors | Status | Code | When | | ------ | ------------------------------------------------------ | -------------------------------------------------------------- | | `400` | [`invalid_request`](/errors/invalid_request) | Malformed request, for example an invalid cursor. | | `401` | [`authentication_error`](/errors/authentication_error) | Missing or invalid credentials. | | `403` | [`permission_denied`](/errors/permission_denied) | Missing scope, or an unprovisioned subject selector. | | `404` | [`not_found`](/errors/not_found) | The resource does not exist, or is not visible to this caller. | | `409` | [`conflict`](/errors/conflict) | A conflict with the current state of the resource. | | `422` | [`validation_error`](/errors/validation_error) | The request was understood but failed field validation. | | `429` | [`rate_limit_exceeded`](/errors/rate_limit_exceeded) | Rate limit exceeded. Retry after the Retry-After interval. | | `503` | [`service_degraded`](/errors/service_degraded) | A dependency is temporarily unavailable. Safe to retry. | Every error is an RFC 9457 `application/problem+json` body carrying a stable `code`, a `requestId`, and a `suggestedAction` where Exo has one.
