- `Snapshot(Value: Text)`: The snapshot parameter is an opaque DateTime value that, when present, specifies the blob snapshot to retrieve.
- `Prefix(Value: Text)`: Filters the results to return only blobs whose names begin with the specified prefix.
- `Delimiter(Value: Text)`: When the request includes this parameter, the operation returns a BlobPrefix element in the response body that acts as a placeholder for all blobs with names that begin with the same substring until the delimiter character is reached. The delimiter may be a single character or a string.
- `MaxResults(Value: Integer)`: Specifies the maximum number of blobs to be fetch, from 1 to 5000 if not defined it will fetch 5000 If more than 5000 blobs then use NextMarker to fetch the next set of blobs. In certain cases, the service might return fewer results than specified by maxresults, and also return a continuation token....

- `GetParameters(): Dictionary of [Text, Text]` (internal)

Plus 2 local procedures.

## Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 9044 "ABS Format Helper"](../codeunit/9044.md) (5 calls: `LeaseId → RemoveCurlyBracketsFromString`, `Snapshot → GetRfc1123DateTime`, `SourceIfModifiedSince → GetRfc1123DateTime`, …)

## Called by

- [Codeunit 9051 "ABS Client Impl."](../codeunit/9051.md) (13 calls: `AcquireLease → LeaseAction`, `AcquireLease → LeaseDuration`, `AcquireLease → ProposedLeaseId`, …)
- [Codeunit 9042 "ABS Operation Payload"](../codeunit/9042.md) (2 calls: `SetOptionalParameters → GetParameters`, `SetOptionalParameters → GetRequestHeaders`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC24

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "codeunit", object_name: "ABS Optional Parameters")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
