## Fields on this page

Layout controls in source order, grouped by the container they sit in. Shows: the table field a control is bound to (or its expression as written); ToolTip: the control's own, else the bound field's (marked).

| Group | Control | Shows | ToolTip |
|---|---|---|---|
| Group | packageId | `Rec."Package ID"` | — |
|  | id | `Rec.ID` | — |
|  | displayName | `Rec.Name` | — |

|  | isInstalled | `isExtensionInstalled` | — |
|  | publishedAs | `Rec."Published As"` | TODO(pteisolation) We should remove the code cop error for API pages |

## Procedures

- `install(var ActionContext: WebServiceActionContext)`
- `uninstall(var ActionContext: WebServiceActionContext)`

## Triggers

OnAfterGetCurrRecord, OnOpenPage

## 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 2504 "Extension Management"](../codeunit/2504.md) (5 calls: `install → InstallExtension`, `install → IsInstalledByPackageId`, `OnAfterGetCurrRecord → IsInstalledByPackageId`, …)
- [Codeunit 457 "Environment Information"](../codeunit/457.md) (1 call: `OnOpenPage → IsSaaS`)

## Across versions

- Present in: BC29-30
- Changed (declaration) in: none

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: "page", object_name: "APIV1 - Aut. Extensions")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
