Requests the câmara's acceptance of a withdrawal — voluntary or required — of guarantee, margin or securities (Vol II, Evento LDL1006 Descrição). The câmara answers per asset, accepting or rejecting each one it was sent (Evento LDL1006 Observação), so a single answer can carry both outcomes. The request is minted, built, signed, encrypted and durably recorded BEFORE anything reaches the queue, so this returns 202 with the control number the câmara will echo; the answer (LDL1006R1) arrives asynchronously and is read back with getLDL1006. Every amount and quantity is a decimal STRING carried to the wire exactly as written. A deployment with no send leg configured answers 503 with SILOC-0023; one whose dispatcher is not running answers 503 with SILOC-0024. ## OpenAPI ````yaml /es/openapi/v3-current/siloc.yaml post /api/v1/siloc/outbound/withdrawal-acceptance-requests openapi: 3.1.0 info: description: >- OpenAPI 3.1 surface for Lerian SILOC, the participant-side rail connecting the institution to Núclea's SILOC deferred-net interbank settlement. title: Lerian SILOC API version: 1.0.0 servers: - url: https://siloc.sandbox.lerian.net security: [] paths: /api/v1/siloc/outbound/withdrawal-acceptance-requests: post: tags: - Collateral summary: Ask the câmara to accept a collateral withdrawal description: >- Issues a LDL1006 to the Câmara LDL on behalf of an Entidade Responsável (Catálogo de Serviços do SFN v5.13, Vol II).
