Automate Cegid Loop 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.

• Entries À corriger in every dossier, each morning

  Build this

  Starts

  Every weekday at 7:30

  Step 1

  For each dossier you name, list the entries to correct with status À corriger.

  Step 2

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

  Step 3

  Email you the list, one section per dossier, with the controls each entry fails.

• Last month's Grand Livre, sent to your reporting system

  Build this

  Starts

  Monthly, on the 5th at 8:00

  Step 1

  For each dossier, get the Grand Livre for the previous month.

  Step 2

  Stop for a dossier with no entry lines.

  Step 3

  Post the lines, with debit, credit and accounts, to your reporting or ERP webhook.

• Weekly Balance de révision changes

  Build this

  Starts

  Every Monday at 8:00

  Step 1

  For each dossier, read the Balance de révision.

  Step 2

  Keep the accounts whose balance changed since the last run.

  Step 3

  Have an AI step summarize the changes per dossier and email you the summary.

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 Grand Livre of a dossier” would look like.

curl https://api.fous.com/v1/runs \

      }
    ],
    "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.

Cegid Loop’s own options

Cegid publishes Cegid Loop APIs for entries, the balance, the chart of accounts, tiers and documents. A firm administrator generates the APIKey in CegidLife: Standard is free and can be shared with partners, Advanced is billable and for the firm itself. Calls also need a subscription key from a Cegid contact.

Signing in to Cegid Loop

Cegid Loop signs you in at loop.loopsoftware.fr, on a sign-in address with your firm's own path, with a Microsoft 365 account whose password is changed at office.com. Clients on a collaborative offer sign in with the login they gave their accountant and a password. With Fous you sign in once through Cegid Loop's own sign-in with your own account, and the login is sealed with AES-256.

Worth knowing

Opening an entry marks it as seen

In the Écritures control interface, selecting an entry switches it to Vue and it leaves the list of unseen entries. The interface is a Preview feature you request from your CSM, for profiles 3 and above.

Ten controls decide an entry's status

Entries are À corriger, À vérifier or Conforme. The controls include a missing label, reference, due date or supporting document, a suspense account, and duplicate invoices or payments.

The balance shows the comparative periods

The Balance de révision shows the periods set in Dossier > Exercices > Modifier. Client and supplier balances have to be condensed before a multi-period export.

The API needs two keys and a retry policy

Each call carries the APIKey (key, colon, client secret) in an x-apikey header and a subscription key. Cegid advises a retry policy because some APIs may sometimes be unavailable.
