Automate CARM with a workflow

A workflow runs your methods as one process, with nobody at the screen. A schedule or a call from your own system starts it, the steps run in order, and the result arrives in your inbox or in the systems you already use.

• Releases still waiting for a CAD, every RM account

  Build this

  Starts

  Every weekday at 8:00 Eastern

  Step 1

  For each RM account you name, list the releases without a CAD.

  Step 2

  Keep the releases that were not on the last run, or whose CAD deadline is today or tomorrow.

  Step 3

  Email you the list by RM account, with transaction number, release date and CAD deadline.

• Statement of Account to your accounting system

  Build this

  Starts

  Monthly on the 26th at 9:00 Eastern, the day after the SOA is issued

  Step 1

  For each RM account, get the Statement of Account for the billing period that just closed.

  Step 2

  Post the account, billing period, payment due date and balance to your ERP webhook.

  Step 3

  Email you a one-line summary per account.

• New penalty assessments and credits on your account

  Build this

  Starts

  Every weekday at 7:00 Eastern

  Step 1

  Get the transaction history for each RM account for the last 3 days.

  Step 2

  Keep the penalty assessments, payments and refunds not there on the last run.

  Step 3

  Post each one, with transaction number, type, amount and due date, to your webhook.

You can run a workflow by hand on every plan, Free included. Schedules and webhook triggers come with the paid plans, from $29 a month.

Once built, one call from your code

Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get the Statement of Account” would look like.

    ]
  }
}

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

CARM’s own options

The CBSA accepts commercial accounting declarations and their corrections through the CARM Client Portal, EDI or an API, and lists a CARM Open API catalog. To file by EDI or API, an importer or broker first applies through the CBSA's online client support contact form. Daily Notices come only by EDI, and statements can be sent by EDI after a BSF815 request.

Signing in to CARM

CARM signs you in with a GCKey or with a Sign-in Partner through Interac, then sends a one-time passcode by email at every sign-in. The passcode expires after 5 minutes and the step cannot be turned off. With Fous you sign in once through CARM's own sign-in with your own account: the login is sealed with AES-256, the emailed code is handled, and an expired session is signed back in.

Worth knowing

Five business days to account

A Type AB CAD must be accepted within 5 business days of release, with the release day as day zero. When it is late, a $100 late accounting penalty is applied automatically and appears on that period's SOA.

Statements on the 25th, payment 10 weekdays later

The SOA covers goods released from the 18th of one month to the 17th of the next and is issued on the 25th. Payment is due 10 weekdays, holidays included, after the 17th: 30 October for the October 2026 statement.

Corrections close on the payment due date

Corrections are open to RPP importers and their delegated broker until 11:59:59 pm on the payment due date and need a reason code and remarks. Supporting documents go only through the portal, up to 45 MB a file.

No Daily Notice in the portal

The Daily Notice is sent only by EDI. In the portal the same postings appear in Transaction history in real time, so a daily workflow can read that page instead.
