Update Tax Treatment
PUT/api/ledger/connections/:connectionId/tax-treatment
Set who computes the tax on documents pushed to this connection.
This endpoint currently requires session authentication; Personal Access Token scope support is in progress.
Authentication: Requires Bearer token.
Body fields:
mode(string, required) —provider_computedorposted_as_line.
Forward-only: changing the mode never re-pushes documents that already synced — it only affects how the next document is built. In provider_computed mode, a document whose line carries an unmapped tax rate will fail to sync with an actionable error until the rate is mapped.
Returns the refreshed tax-treatment state. Returns 404 when the connection id does not name the configured accounting connection; 422 when the mode is not a known option.

Response Headers
Unauthenticated — the bearer token is missing, revoked, expired, or malformed. Never retry automatically; fix the credential. See the Errors guide.
Forbidden — the token lacks a required scope, the endpoint is not available to API tokens, or the user behind the token lacks the permission. A human must adjust the token scopes or user permissions; do not retry.
Not found — no record with the given identifier (or the route does not exist). Verify the ID before retrying.
Unprocessable Entity
Response Headers
Rate limited — platform limit is 1,000 requests/min; individual tokens may carry lower limits. Honor the Retry-After header before retrying. See the Rate Limits guide.
