These URLs are required when creating submissions via a message queue. You can choose one of the following options for your submission retrieval store: - Amazon S3 - Open Computer and Software Inventory (OCS) - Deprecated in v43, with support ending in v46 - Not supported for SaaS instances - General web storage (HTTP / HTTPS) - Azure Blob Storage - Supported in v39.2 and later - Google Cloud Storage (GCS) - Supported in v42 and later ## Setting up your submission retrieval store To set up your submission retrieval store, follow the instructions in the “Submission Initialization” or “Submission Bootstrap” section of the “Flow Blocks” article for your version of Hyperscience ( [v38](/v38/docs/flow-blocks#submission-initialization) | [v39](/v39/docs/flow-blocks#submission-initialization) | [v40](/v40/docs/flow-blocks#submission-initialization) | [v41](/v41/docs/flow-blocks#submission-initialization) | [v42](/v42/docs/flow-blocks#submission-bootstrap) | [v43](/v43/docs/flow-blocks#submission-bootstrap) ). If you are using an S3 bucket as a submission retrieval store, you need to configure its permissions as described in [S3 Submission Retrieval Store](/deployment/docs/s3-submission-retrieval-store).
