By default the customer must first claim non-custodial control via POST /v2/customers/{id}/wallets/claim-non-custodial; for organizations enabled for custodial wallets, the account is provisioned on the first call to this endpoint with no claim required. An idempotency-key header is required. For post-activation non-custodial accounts, returns 202 with a ceremonyId and verificationUrl when admin approval is required. ## OpenAPI ````yaml https://api.sandbox.conduit.financial/v2/api-docs/openapi.json post /customers/{customerId}/wallets openapi: 3.0.0 info: title: Conduit Sandbox API description: >- **Sandbox API** — clients integrate against this surface to exercise happy and unhappy paths without consuming real KYC/PSP credits or moving real money.

One or more fields have invalid values, missing required properties, or incorrect types.

Bodies declared as 'application/json' — and bodies with no Content-Type header, which are assumed to be JSON — must contain syntactically valid JSON. **IDEMPOTENCY_KEY_REQUIRED**: This endpoint requires an Idempotency-Key header to prevent duplicate processing. Generate a unique key per logical request and resend the request. **IDEMPOTENCY_KEY_INVALID**: The Idempotency-Key header value did not match the required shape (1-128 characters, letters / digits / underscore / dot / colon / hyphen). **IDEMPOTENCY_BODY_TOO_NESTED**: The request body exceeds the maximum nesting depth allowed by the idempotency fingerprint hasher.

Concurrent requests with the same key are rejected to prevent duplicate execution. **CONFLICT**: The request conflicts with the current state of the resource. This usually means a duplicate or a state transition that is not allowed. **WALLET_CUSTODY_NOT_CLAIMED**: The customer's wallet account is custodial, but custodial wallets are not enabled for this organization.
