Replace the export map
Replaces one export system’s whole account map and makes that system the workspace’s active one. system is a lowercase name of at most 32 characters, such as ledger_one; entries names each account once, at most 1,000 in all, and an account left out leaves the map. Answers the map as saved, and 409 when another save of it is under way. Every mapping read then answers stale: true until that mapping has been prepared again with the new codes, and extraction.mapped announces each one. Requires a plan that includes spreads; other plans get a 403.
Requires the chart_of_accounts:write scope. Rate limit: 200 requests per minute per key (the api lane).
Authentication
Bearer token. Use ss_live_… for live data or ss_test_… for the sandbox (test mode). See Authentication.
Headers
Idempotency token. Retries that reuse the key within 24h replay the original response. Up to 255 characters; a UUID is typical. See Idempotency.
Pin the API version, e.g. 2026-07-19. Omit to get the latest. See Versioning.
Request
The export system's name: a lowercase letter followed by up
to 31 lowercase letters, digits, underscores or hyphens, such as
ledger_one.
Response headers
Set to true when the response is replayed from the idempotency cache for a request that re-presented an Idempotency-Key it had already used. Absent on the original (winner) response. A replay repeats the original status and body. When the original could not be stored (an unhandled server fault, or a body over the 1 MiB replay cap) the replay is an error envelope that says so; the operation is never re-run under the same key.
The API surface version the server resolved for this request. Always present, regardless of whether the client supplied the request-side SpreadSpace-Version header. Default: 2026-07-19.
Request budget of the endpoint's rate-limit policy per 60-second sliding window. See Rate limits.
Requests left in the current window. Suppressed on 429 responses produced outside the rate limiter (for example a usage throttle), where a remaining budget would be misleading.
