Automate iConnectData 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.

• Yesterday's declined transactions, every customer ID

  Build this

  Starts

  Every weekday at 7:00

  Step 1

  For each customer ID you name, get yesterday's real-time transaction history with the status Declined.

  Step 2

  Stop when there are none.

  Step 3

  Email you the list grouped by cardholder, with card number, merchant name and authorized amount.

• Posted transactions, handed to your accounting system

  Build this

  Starts

  Every day at 6:00

  Step 1

  For each customer ID, get the last 7 days of real-time transaction history with the status Posted.

  Step 2

  Keep the transactions that were not there on the last run.

  Step 3

  Post each one, with cardholder, card number, merchant, MCC and posted amount, to your ERP webhook.

• Express Codes with a balance left or a check Pending

  Build this

  Starts

  Every Monday at 8:00

  Step 1

  For each customer ID and sequence number in your list, check the Express Check code activity.

  Step 2

  Keep the codes with a balance above zero or a check still Pending.

  Step 3

  Email you the list with original amount, amount used and balance.

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 real-time transaction history” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "w6.iconnectdata.com/get_real_time_transactions",
    "input": {
      "customer_id": "AC123",

      "start_date": "2026-11-10",
      "end_date": "2026-11-11"
    }
  }'

        "mcc": "5542",
        "currency_code": "USD"
      }
    ],
    "count": 1
  }
}

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.

IConnectData’s own options

Comdata offers web services (WSDL requests over SOAP) for its Fleet Card, Mastercard and Virtual Card programs, and REST APIs through a developer portal. Comdata says any action in its web interfaces can also be done with its web services, such as ordering and blocking cards. Access goes from a mock service to a sandbox to production, after a skill certification with Comdata's technical team. No price is published.

Signing in to iConnectData

iConnectData asks for your username and password, then a six-digit single-use code from the verification method you set up: Okta Verify or Phone. Signing in again from the same IP address can skip the code for 12 hours. With Fous you sign in once through iConnectData's own sign-in with your own account: the login is sealed with AES-256 and never shown to code or AI agents.

Worth knowing

45 days at a time, 180 days back

Real Time Transaction History searches at most 45 days within the previous 180 days. For a longer period, call the method once per 45-day window.

Reports run, then you download them

A reportQ report is listed under Report Status and History with a Report Running icon until it is ready. The Download link appears in the Action field only then.

Express Code fees: P or L

Each Express Code carries a fee code: P invoices the fee to your company, L deducts it from the check's balance. Display Charges shows the charges before you retrieve the code.

Access follows customer IDs

Real Time Transaction History filters by account code, five digits assigned by Comdata, and customer ID. Without access to a customer ID, or the authority for an action, Express Check shows an error.
