## Properties

| Property | Value |
|---|---|
| Caption | Contact Sync User |
| DataClassification | CustomerContent |

## Fields

Explanation: the field's ToolTip in the code; without one, the ToolTip of a page control bound to the field (marked via the page); without that, its Caption (marked caption) when that differs from the name.

| No. | Name | Type | Explanation | Notes |
|---|---|---|---|---|
| 1 | ID | Integer | — | AutoIncrement; DataClassification SystemMetadata |
| 2 | User ID | Code[50] | — | TableRelation User."User Name"; NotBlank; DataClassification EndUserIdentifiableInformation |
| 3 | Last Sync Date Time | DateTime | — | not editable; DataClassification SystemMetadata |
| 4 | Folder ID | Text[250] | — | DataClassification SystemMetadata |
| 5 | Delta Url | Text[2048] | Delta URL <small>caption</small> | DataClassification SystemMetadata |
| 6 | Folder Name | Text[250] | — | DataClassification SystemMetadata |

## Keys

- PK: ID (clustered)
- UserFolder: User ID, Folder ID
- FolderEmail: Folder ID
- UserFolderSync: User ID, Folder ID, Last Sync Date Time

## Trigger event subscribers

- OnBeforeInsertEvent: [Codeunit 7100 "Contact Sync User Subscriber"](../codeunit/7100.md) OnBeforeInsertContactSyncUser
- OnBeforeModifyEvent: [Codeunit 7100 "Contact Sync User Subscriber"](../codeunit/7100.md) OnBeforeModifyContactSyncUser

## Procedures

- `SetDeltaUrl(NewDeltaUrl: Text)`
- `GetDeltaUrl(): Text`
- `EnforceRecordOwnership()` (internal)
- `EnforceRecordOwnershipOnModify(OriginalUserId: Code[50])` (internal)
- `ValidateApprovedGraphDeltaUrl(DeltaUrlToValidate: Text): Boolean` (internal)

## 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 3060 "Uri"](../codeunit/3060.md) (1 call: `ValidateApprovedGraphDeltaUrl → ValidateIntegrationURL`)

## 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: "table", object_name: "Contact Sync User")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
