## 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 |
|---|---|---|---|
| Control1 | Name | [Description](../table/812.md#fields) | Specifies the name of the API page or query. |
|  | Type | [Object Type](../table/812.md#fields) | Specifies whether the API is implemented as an API page (read and write operations), an API query (read-only set of data), or an API codeunit (operations exposed as unbound actions). |
|  | ID | [Object ID](../table/812.md#fields) | Specifies the object ID of the underlying API page or query. Use this when troubleshooting integrations together with a developer. |
|  | API Publisher | [API Publisher](../table/812.md#fields) | Specifies the publisher segment of the API URL. The publisher identifies who owns the API and is part of the route used by external systems. |
|  | API Group | [API Group](../table/812.md#fields) | Specifies the group segment of the API URL. Use the API group to scope integrations to a related set of endpoints. |
|  | Entity | [Entity Name](../table/812.md#fields) | Specifies the entity that the API exposes. The entity name appears in the API URL and helps identify the originating solution. |
|  | API Version | [API Version](../table/812.md#fields) | Specifies the version segment of the API URL. Choosing the right version ensures compatibility when integrating with external systems. |
|  | API URL | `GetApiUrl(Rec)` | Specifies the full URL of the API endpoint in this environment. Choose the link to open the endpoint, for example to inspect its metadata or test a request. |

## Ask your agent

Procedure bodies are not stored here (D10). 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: "API Overview")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
