## 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 2356 "Http Response Message"](../codeunit/2356.md) (17 calls: `GetAsJson → GetContent`, `GetAsJson → GetException`, `GetAsJson → GetIsSuccessStatusCode`, …)
- [Codeunit 2354 "Http Content"](../codeunit/2354.md) (3 calls: `PatchAsJson → Create`, `PostAsJson → Create`, `PutAsJson → Create`)
- [Codeunit 2352 "Http Request Message"](../codeunit/2352.md) (2 calls: `Authorize → SetHeader`, `SendRequest → GetRequestUri`)
- [Codeunit 2362 "Rest Client Exception Builder"](../codeunit/2362.md) (1 call: `SendRequest → CreateException`)

## Called by

- [Codeunit 2350 "Rest Client"](../codeunit/2350.md) (14 calls: `AddCertificate → AddCertificate`, `Create → Create`, `GetAsJson → GetAsJson`, …)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC26

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: "Rest Client Impl.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
