Never invent compatibility fields, alternate endpoints, or additional source models. > Preserve explicit nulls, decimal strings, timestamps, source identifiers, immutable version identifiers, and document-version links exactly as defined. # Retry a failed webhook delivery > Requeues a dead-lettered delivery without changing its event, body, timestamp, key version, or signature. ## OpenAPI ````yaml /openapi/ingestion.openapi.yaml post /api/ingestion/webhook-endpoints/{endpointId}/deliveries/{deliveryId}/retry openapi: 3.1.0 info: title: Karsa Data Ingestion API version: current description: >- Source-bound writes for documents, business onboardings, customers, kyb-dossiers, accounts, transactions, outcomes, screening observations, screening dispositions, monitoring controls, monitoring control executions, historical RFI events, source checkpoints, native SEON screening observations, native AiPrise screening observations, and native Chainalysis screening observations. servers: -
