# Save business approval rules (Sandbox)

`POST /money/test_approval_rules`

## Request

- Base URL: `https://api.stablesea.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.stablesea.com/money/test_approval_rules`
- Auth: none declared

Uses your business's isolated Sandbox data with your existing signed-in member permissions. Replaces changed business approval rules and records the signed-in administrator. Unchanged saves retain the current version without notices. Send expected_version_id from GET to reject stale changes with 409. Requires `approval_controls_manage` in enforced mode or `permissions_manage` in legacy mode. Rule writes must be enabled. Send an Idempotency-Key to prevent duplicate revisions and notices on retry; a duplicate returns 409. Read the current rules after an uncertain response.

## Headers

- `Idempotency-Key` string: Optional client idempotency key; a duplicate save with the same key is rejected with 409 without another revision or notice.

## Request body

- MoneyMovementsPutApprovalRulesInput
  - `expected_version_id` string, nullable: Optional current version from GET. Empty means expect no version. Stale returns 409; omission retains compatible serialized replacement.
  - `rules` MoneyMovementsApprovalRuleInput[], nullable, required
    - `also_required_ind_id` string
    - `comparison` 'gt' | 'gte'
    - `flows` MoneyMovementsApprovalFlow[], nullable, required
    - `id` string: Current rule reference; omit min_amount_usd to retain its exact stored threshold.
    - `min_amount_usd` string, nullable: Exact USD threshold. Omit only with a current rule id to retain its server-known amount.
    - `required_approvals` integer, required

    - `individual_id` string
    - `selected_eligible` boolean
  - `gateable_flows` MoneyMovementsApprovalFlow[], nullable
