Esri ArcGIS Online (AGOL) Feature Service Writer Parameters

Service Connection

These are the credentials required to log into ArcGIS Online.

Constraints

Note: Writers created before FME 2022.1 will have a single Feature Service parameter which is used to specify the feature service.

Feature Service

This parameter specifies the Feature Service for which to write features. Click the Browse button to obtain a list of all Feature Services accessible by the current user. A connection window appears while the system browses all accessible folders and groups for Feature Services. You can select only one Feature Service.

This parameter takes the form of folder or group name/feature service name, and is optionally suffixed with the Feature Service Item ID if the name is ambiguous. Note that a group name can only be used to specify an existing feature service. If you wish to share a new feature service with a group, you can first create it in your own account and then share it to the group with the Esri ArcGIS Online Connector.

Constraints

Item Source

This parameter is used to determine whether the feature service to write to will be specified using a user folder or a group.

  • User Content (default) – Select this option when writing to a user folder.

  • Group – Select this option only when writing to an existing feature service.

Folder

This parameter is used when Item Source is set to User Content and specifies the name of the target folder for the feature service.

The default value of / (forward slash) represents the root user folder. Clicking the Browse button will display a list of a user’s folders.

Group

This parameter is used when Item Source is set to Group and specifies the ID of a group for an existing feature service. Clicking the Browse button will display a list of the groups a user belongs to, as well as all the groups in their organization.

Feature Service

This parameter is used to specify a single feature service. Clicking the Browse button will display a list of all the feature services in the selected group or user folder. If selecting an existing feature service, the Feature Service Item ID will be appended to the name of the feature service.

Assuming the correct user folder is selected, these are all valid ways to specify an existing feature service with name My Feature Service and ID 567aba67c25cb60ee159d3fbe2b16eff:

  • My Feature Service(567aba67c25cb60ee159d3fbe2b16eff)

  • (567aba67c25cb60ee159d3fbe2b16eff)

  • My Feature Service

Tips:

  • To create a new feature service, provide only the name of the new feature service.

  • If you manually enter an ID, you must enclose it within parentheses. Providing a Feature Service Item ID will override the destination specified by the User Folder or Group parameters. The provided ID must match a Feature Service item on ArcGIS Online; otherwise, the writer will fail when the translation is run.

Feature Service Handling

This parameter is only available when Item Source is set to User Content.

  • Use Existing – This is the default value.
  • Create If Needed – If the specified Feature Service does not exist in the specified folder, the ArcGIS Online Feature Service Writer will create it. Refer to Feature Service Creation for details regarding this procedure.
  • Overwrite – If the specified Feature Service exists, it will be overwritten. Otherwise, this is identical to Create If Needed.

Tips:

  • When creating or overwriting a feature service, the feature operation of all the writer’s feature types should be set to Insert. Note that the Feature Type Handling option should not be set to Truncate Existing.

  • If you wish to share a new feature service with a group, you can first create it in your own account and then share it to the group using the Esri ArcGIS Online Connector.

Publishing

Target WKID

This optional parameter specifies the target spatial reference of the published Feature Service. It’s only applicable when the writer creates a Feature Service.

The default value is WKID 102100. This value corresponds to the Web Mercator projection, which is the standard projection used to create XYZ tiled web maps. If not specified, the server default is used (which is typically also WKID 102100).

Advanced

This parameter specifies the maximum number of features that may be present in a single write request to the server. This limit applies to Insert, Update, Delete, Upsert, and truncation. The writer will issue a request to the server whenever a single feature type accumulates the number of output features specified by this parameter.

Note: This parameter is only applicable when writing to an existing Feature Service. If the Feature Service was created in the same translation, then this parameter is ignored.

This parameter is useful for avoiding server timeouts or HTTP 500 responses that may result from long write operations.

If this parameter is not provided, it defaults to 1000.

This parameter specifies whether Global IDs are to be used as the primary key for write operations, instead of Object IDs. Enabling this parameter is necessary in order to use the Upsert feature operation. This behavior may be necessary to use some ArcGIS features, such as Feature Service Sync.

When this parameter is set to Yes, it remains possible to insert features without a value for the Global ID attribute.

If this parameter is not provided, it defaults to No.

Note: A warning is logged if this parameter is set to Yes, but the Feature Service created during the translation has feature types that did not define a Global ID attribute. An error is raised if this parameter is set to Yes, but the server or Feature Service does not support Global IDs.

When Use Global IDs is set to Yes, this parameter determines the behavior during Insert/Upsert operations when a feature without a Global ID value is encountered.

  • Yes – An error is raised if the feature does not have a Global ID. This is the default behavior for workspaces created before FME 2020.2.
  • No – Auto-generated Global IDs are assigned to features without one.
