moov-io/ofac

Office of Foreign Asset Control (OFAC) is an HTTP API and Go library to download, parse and serve United States OFAC sanction data along with the BIS Denied Person's List (DPL) for applications and humans. Also supported is an async webhook notification service to initiate processes on remote systems connected with OFAC. The US Treasury department offers a search page for OFAC records.

All United States companies are required to comply with OFAC regulations and sanction lists and the US Patriot Act requires compliance with the BIS Denied Person's List (DPL). Moov's primary usage for this project is with ACH origination in our paygate project.

To get started using OFAC download the latest release or our Docker image. We also have a demo OFAC instance as part of Moov's demo environment.

We offer hosted api docs as part of Moov's tools and an OpenAPI specification for use with generated clients.

Web UI

OFAC ships with a web interface for easier access searching the records. Our Docker image hosts the UI by default, but you can build and run it locally as well.

$ make
...
CGO_ENABLED=1 go build -o ./bin/server github.com/moov-io/ofac/cmd/server
...
npm run build
...
Success!

$ go run ./cmd/server/ # Load http://localhost:8084 in a web browser

Configuration

Environmental Variable	Description	Default
OFAC_DATA_REFRESH	Interval for OFAC data redownload and reparse. off disables this refreshing.	12h
OFAC_DOWNLOAD_TEMPLATE	HTTP address for downloading raw OFAC files.	(OFAC website)
DPL_DOWNLOAD_TEMPLATE	HTTP address for downloading the DPL	(BIS website)
INITIAL_DATA_DIRECTORY	Directory filepath with initial files to use instead of downloading. Periodic downloads will replace the initial files.	Empty
WEBHOOK_BATCH_SIZE	How many watches to read from database per batch of async searches.	100
LOG_FORMAT	Format for logging lines to be written as.	Options: json, plain - Default: plain
BASE_PATH	HTTP path to serve API and web UI from.	/
HTTP_BIND_ADDRESS	Address for OFAC to bind its HTTP server on. This overrides the command-line flag -http.addr.	Default: :8084
HTTP_ADMIN_BIND_ADDRESS	Address for OFAC to bind its admin HTTP server on. This overrides the command-line flag -admin.addr.	Default: :9094
HTTPS_CERT_FILE	Filepath containing a certificate (or intermediate chain) to be served by the HTTP server. Requires all traffic be over secure HTTP.	Empty
HTTPS_KEY_FILE	Filepath of a private key matching the leaf certificate from HTTPS_CERT_FILE.	Empty
DATABASE_TYPE	Which database option to use (Options: sqlite, mysql)	Default: sqlite
WEB_ROOT	Directory to serve web UI from	Default: examples/ofac-search-ui/build/

Storage

Based on DATABASE_TYPE the following environment variables will be read to configure connections for a specific database.

MySQL

• MYSQL_ADDRESS: TCP address for connecting to the mysql server. (example: tcp(hostname:3306))
• MYSQL_DATABASE: Name of database to connect into.
• MYSQL_PASSWORD: Password of user account for authentication.
• MYSQL_USER: Username used for authentication,

Refer to the mysql driver documentation for connection parameters.

• MYSQL_TIMEOUT: Timeout parameter specified on (DSN) data source name. (Default: 30s)

SQLite

• SQLITE_DB_PATH: Local filepath location for the paygate SQLite database. (Default: ofac.db)

Refer to the sqlite driver documentation for connection parameters.

Features

• Download OFAC and BIS Denied Persons List (DPL) data on startup
  • Admin endpoint to manually refresh OFAC and DPL data
• Index data for searches
• Async searches and notifications (webhooks)
• Manual overrides to mark a Company or Customer as unsafe (blocked) or exception (never blocked).
• Library for OFAC and BIS DPL data to download and parse their custom files

Webhook Notifications

When OFAC sends a webhook to your application the body will contain a JSON representation of the Company or Customer model as the body to a POST request. You can see an example in Go.

An Authorization header will also be sent with the authToken provided when setting up the watch. Clients should verify this token to ensure authenticated communicated.

Webhook notifications are ran after the OFAC data is successfully refreshed, which is determined by the OFAC_DATA_REFRESH environmental variable.

Watching a specific Customer or Company by ID

OFAC supports sending a webhook periodically when a specific Company or Customer is to be watched. This is designed to update another system about an OFAC entry's sanction status.

Watching a customer or company name

OFAC supports sending a webhook periodically with a free-form name of a Company or Customer. This allows external applications to be notified when an entity matching that name is added to the OFAC list. The match percentage will be included in the JSON payload.

Prometheus Metrics

• http_response_duration_seconds: A Histogram of HTTP response timings
• ofac_match_percentages A Histogram which holds the match percentages with a label (type) of searches
  • type: Can be address, q, remarksID, name, altName
