## What you can build on Cegid Loop

### Get the Grand Livre of a dossier

Reads the Grand Livre (general ledger) of one client dossier for a period, one row per entry line, with the columns the ledger export uses.

- Takes: Dossier, period start, period end, account (optional)
- Returns: Entry date, journal, document number, general account and label, auxiliary account, entry label, debit, credit, due date

### Read the Balance de révision

Reads Révision > Balance de révision (trial balance) for one dossier, with the comparative periods set for its exercices.

- Takes: Dossier
- Returns: Account number, account label and balance for each period shown

### List entries to correct

Reads the Écritures tab's control interface for one dossier: entries in status À corriger or À vérifier, with their journal type and the controls they fail.

- Takes: Dossier, status (optional)
- Returns: Entry date, journal type, label, amount, status, failed controls

## Automate Cegid Loop with a workflow

A [workflow](/product/workflows) 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

Starts: Every weekday at 7:30

1. For each dossier you name, list the entries to correct with status À corriger.
2. Keep the entries that were not there on the last run.
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

Starts: Monthly, on the 5th at 8:00

1. For each dossier, get the Grand Livre for the previous month.
2. Stop for a dossier with no entry lines.
3. Post the lines, with debit, credit and accounts, to your reporting or ERP webhook.

### Weekly Balance de révision changes

Starts: Every Monday at 8:00

1. For each dossier, read the Balance de révision.
2. Keep the accounts whose balance changed since the last run.
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](/product/methods), 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.

Example request:

```
curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "loop.loopsoftware.fr/get_grand_livre",
    "input": {
      "dossier": "Northwind SARL",
      "period_start": "2026-10-01",
      "period_end": "2026-10-31",
      "account": "401"
    }
  }'
```

Example response:

```
{
  "status": "completed",
  "data": {
    "dossier": "Northwind SARL",
    "lines": [
      {
        "date_ecriture": "2026-10-06",
        "journal": "AC",
        "numero_piece": "F-2026-1184",
        "compte_general": "401000",
        "libelle_compte_general": "Fournisseurs",
        "compte_auxiliaire": "ACME",
        "libelle_ecriture": "Acme facture octobre",
        "debit": 0,
        "credit": 1440,
        "date_echeance": "2026-11-05"
      }
    ],
    "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.

| Option | What it covers | What it takes |
| --- | --- | --- |
| Cegid Loop APIs | Écriture comptable, Import des écritures comptables, Balance, Plan de comptes, Tiers, Codes TVA, Document management, Dossier Complet and more. | An APIKey from CegidLife set in LoopHub by an administrator (Standard free, Advanced billable) and a subscription key from your Cegid referent. |
| Excel Loop Connector | Exports the Grand Livre of a dossier to Excel with its standard columns. | Excel and access to the dossier in Cegid Loop. |
| Cegid Loop by hand | The Grand Livre, the Balance de révision and the Écritures control interface, one dossier at a time, copied to Excel when needed. | A Cegid Loop account with a Microsoft 365 login and rights to the dossier. |

## 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.

## Frequently asked questions

### Does Cegid Loop have an API?

Yes. Cegid publishes Cegid Loop APIs for entries, imports, the balance, the chart of accounts, tiers and documents. A firm administrator generates an APIKey in CegidLife, free (Standard) or billable (Advanced), and a Cegid contact issues the subscription key the calls also need.

### How do I export the Grand Livre from Cegid Loop to Excel?

Use the Excel Loop Connector. Its Grand Livre export has columns such as Date d'écriture, Journal, Numéro de pièce, Compte général, Compte auxiliaire, Libellé écriture, Débit, Crédit and Date d'échéance. The Balance de révision can also be copied into Excel with Ctrl+A and Ctrl+C.

### Which browser does Cegid Loop work in?

Chrome, which Cegid says gives the best compatibility, as well as Edge, Firefox and Safari on Mac. Cegid also asks for a Microsoft Office 365 account, at least 4 GB of RAM and 4 Mb/s of bandwidth per person.

### Can I see entries to correct across all my dossiers at once?

The Écritures control interface shows one dossier at a time. With Fous, you can build a workflow that runs on a schedule, loops over your dossiers, calls your entries method for each one and emails you the entries À corriger.

### Is Fous affiliated with Cegid?

No. Fous is an independent product. You use it with your own Cegid Loop account, and a method reads and does only what that account can.

Fous is an independent product: it is not affiliated with, endorsed by or sponsored by the operator of Cegid Loop (Cegid). The name is used only to say which system this page is about. Something here wrong or out of date? Write to legal@fous.com.
