PostingInstructionBatchCreatedEvents are published by the vault.api.v1.postings.posting_instruction_batch.created Kafka response topic.

The Contracts Transaction Bridge consumes messages from vault.api.v1.postings.posting_instruction_batch.created and only processes PostingInstructionBatches where the client_id is “CoreContracts”.

In the case of PostingInstructionBatches that meet the defined criteria the Contracts Transaction Bridge will call the Experience Layer’s Transaction service to create corresponding Transactions for customer accounts.

Transactions are then stored and are available for retrieval or update via the Experience Layer’s API.
