OneDrive Connector

The OneDrive connector uploads to and downloads from the OneDrive cloud storage service.

Key Capabilities

Microsoft OneDrive cloud storage integration with OAuth authentication and automatic token refresh
Bidirectional file transfer functionality with folder-based organization and glob pattern filtering
Optional file deletion after download with overwrite protection
Optional caching to ensure only new or updated files are downloaded

Overview

Each OneDrive connector connects to a specified OneDrive storage account. Within the remote storage, you set a single folder as the upload target and a single folder as the download target. Files that reach the OneDrive connector in the Arc flow are uploaded to the upload target folder, and files found in the download target folder are downloaded and entered into the Arc flow. The connector supports upload and download filters to send and receive only specific file names and/or file extensions. Account authentication uses OAuth, so you must enter account credentials in an external site portal the first time the connector connects. The external portal generates an OAuth token that the connector uses to connect, then the connector handles token refresh automatically.

Connector Configuration

This section contains all of the configurable connector properties.

Settings Tab

Authorization

Setting	Description
Connector Id	The static, unique identifier for the connector.
Connector Type	Displays the connector name and a description of what it does.
Connector Description	An optional field to provide a free-form description of the connector and its role in the flow.

Click the Connect button to authorize the connector with the storage service by redirecting to a site login portal. Once you enter the account credentials in the portal, the resulting authorization token is returned to Arc and stored for repeated use.

Send

Settings related to uploading to the remote storage.

Setting	Description
Remote Folder	Files processed by the connector are uploaded to the folder specified here.
Overwrite	Whether files that already exist in the remote folder should be overwritten or skipped.

Receive

Settings related to downloading from the remote storage.

Setting	Description
Remote Folder	The remote folder from which files are downloaded.
File Mask	A glob pattern that determines which files in the Remote Folder should be downloaded (for example, .txt). If you need to specify multiple file masks, use the Receive Filter* in the Advanced Settings instead.
Delete	Check this to delete successfully downloaded files from the remote storage.

Caching

Settings related to caching and comparing files between multiple downloads.

Setting	Description
File Size Comparison	Check this to keep a record of downloaded file names and sizes. Previously downloaded files are skipped unless the file size is different than the last download.
Timestamp Comparison	Check this to keep a record of downloaded file names and last-modified timestamps. Previously downloaded files are skipped unless the timestamp is different than the last download.

Arc automatically cleans up the resource cache. This process runs in the background during every receive cycle and removes stale cache entries for files that are no longer present on the remote server. This keeps the cache size manageable without requiring any manual action.

By default, files are retained for 30 days, but you can use the ResourceCacheRetentionDays setting in the Other Settings field on the Advanced tab to adjust it to fit your environment. For example, ResourceCacheRetentionDays=15 retains files for 15 days before removing them.

When you enable caching, the file names are case-insensitive. For example, the connector cannot distinguish between TEST.TXT and test.txt.

Advanced Tab

Advanced Settings

Settings not included in the previous categories.

Setting	Description
Recurse	Whether to download files in subfolders of the target remote path.
Timeout	The duration the connector waits for a connection response before throwing a timeout error.
Receive Filter	A glob pattern filter to determine which files should be downloaded from the remote storage (for example, .txt). You can use negative patterns to indicate files that should not* be downloaded (for example, -.tmp). Use this setting when you need multiple File Mask* patterns. Multiple patterns can be separated by commas, with later filters taking priority except when an exact match is found.
Local File Scheme	A scheme for assigning filenames to messages that are output by the connector. You can use macros in your filenames dynamically to include information such as identifiers and timestamps. For more information, see Macros.
Processing Delay	The amount of time (in seconds) by which the processing of files placed in the Transactions tab is delayed. This is a legacy setting. Best practice is to use a File connector to manage local file systems instead of this setting.

Proxy Settings

These are a collection of settings that identify and authenticate to the proxy through which the connection should be routed. By default, this section uses the global settings on the Proxy Settings portion of the Security Settings page. Clear the checkbox to supply settings specific to your connector.

Setting	Description
Proxy Type	The protocol used by a proxy-based firewall.
Proxy Host	The name or IP address of a proxy-based firewall.
Proxy Port	The TCP port for a proxy-based firewall.
Proxy User	The user name to use to authenticate with a proxy-based firewall.
Proxy Password	A password used to authenticate to a proxy-based firewall.
Authentication Scheme	Leave the default None or choose from one of the following authentication schemes: Basic, Digest, Proprietary, or NTLM.

Logging

Settings that govern the creation and storage of logs.

Setting	Description
Log Level	The verbosity of logs generated by the connector. When you request support, set this to Debug.
Log Subfolder Scheme	Instructs the connector to group files in the Logs folder according to the selected interval. The Weekly option (which is the default) instructs the connector to create a new subfolder each week and store all logs for the week in that folder. Leaving this setting blank tells the connector to save all logs directly in the Logs folder. For connectors that process many transactions, using subfolders helps keep logs organized and improves performance.
Log Messages	Check this to have the log entry for a processed file include a copy of the file itself. If you disable this, you might not be able to download a copy of the file from the Transactions tab.

Miscellaneous

Miscellaneous settings are for specific use cases.

Setting	Description
Other Settings	Enables you to configure hidden connector settings in a semicolon-separated list (for example, `setting1=value1;setting2=value2`). Normal connector use cases and functionality should not require the use of these settings.

Automation Tab

Automation Settings

Settings related to the automatic processing of files by the connector.

Setting	Description
Send	Whether files arriving at the connector are automatically uploaded.
Retry Interval	The amount of time before a failed upload is retried.
Max Attempts	The maximum number of times the connector processes the input file. Success is measured based on a successful server acknowledgement. If you set this to 0, the connector retries the file indefinitely.
Receive	Whether the connector should automatically poll the remote download path for files to download.
Interval	The interval between automatic download attempts.
Minutes Past the Hour	The minutes offset for an hourly schedule. Only applicable when the interval setting above is set to Hourly. For example, if this value is set to 5, the automation service downloads at 1:05, 2:05, 3:05, etc.
Time	The time of day that the attempt should occur. Only applicable when the interval setting above is set to Daily, Weekly, or Monthly.
Day	The day on which the attempt should occur. Only applicable when the interval setting above is set to Weekly or Monthly.
Minutes	The number of minutes to wait before attempting the download. Only applicable when the interval setting above is set to Minute.
Cron Expression	A five-position string representing a cron expression that determines when the attempt should occur. Only applicable when the interval setting above is set to Advanced.
Start Date and Time	The date and time at which the automation first runs. Every run after that follows the interval setting above. The last and next run times appear in the Automation Status section.

Automation Status

Performance

Settings related to the allocation of resources to the connector.

Setting	Description
Max Workers	The maximum number of worker threads consumed from the threadpool to process files on this connector. If set, this overrides the default setting on the Performance Settings portion of the Advanced Settings page.
Max Files	The maximum number of files sent by each thread assigned to the connector. If set, this overrides the default setting on the Performance Settings portion of the Advanced Settings page.

Establishing a Connection

All that you need to establish a connection with the OneDrive connector is a set of OneDrive account credentials. Click the Connect button on the Settings tab to be directed to a login portal site. Enter your account credentials in this portal to return an authorization token to the connector. This process is only necessary for the first time the connector connects to the storage service.

Uploading and Downloading

Upload

To upload files, set the Remote Folder field in the Send portion of the Settings page to the folder where files should be uploaded. Each OneDrive connector uploads to a single folder location. Use the Overwrite remote files option to indicate whether files that already exist in the remote folder should be overwritten or skipped. After configuration is complete, files placed in the connector Transactions tab are uploaded to the remote storage. If Send Automation is enabled, the upload happens automatically; otherwise, you can send individual files from the Transactions tab.

Download

To download files, set the Remote Folder field in the Receive portion of the Settings page to the folder where files should be downloaded. Use the File Mask to set a glob filter (for example *.txt) that limits the downloads to files matching the filter. To specify multiple filters, use the Receive Filter option on the Advanced tab. Use Delete to specify whether successfully downloaded files should be removed from the remote storage. After configuration is complete, files are downloaded according to the Receive Automation settings, or you can manually click the Receive button on the Transactions tab.
