Suppliers without IBAN

# Instructions — Suppliers without an IBAN

## ⚠️ No hasIban=false filter

Filters available on `get_suppliers`:
- `ids`, `search`, `isArchived`, `iban` (exact match), `bankCountry`, `vatNumber`
- `createdAfter/Before`, `updatedAfter/Before`, `sortBy`, `sort`

**What does NOT exist**: `hasIban=false` or `ibanIsNull=true`

→ You must retrieve **all suppliers** and filter client-side.

## Step 1 — Paginate through all active suppliers

✅ **Bug resolved (verified 2026-07-22, PR #3169)**: `get_suppliers` no longer returns an `accountPayable.supplierIds` array — tested live with `pageSize=100` on suppliers sharing a consolidated AP account, no response-size overflow. The old risk of exceeding the response limit even at `pageSize=1` (81,179 characters) is no longer reproducible; see [[s22-fournisseurs-actifs-iban]] for details.

```json
{ "companyId": "...", "isArchived": "false", "pageSize": 100, "page": 1 }
```

Repeat with `page=2, 3, ...` until `hasNextPage=false`. **Before starting**: warn the user that this can still take several calls on a large master data set.

⚠️ Do not draw conclusions from the first page only — suppliers with an IBAN may be on other pages.

## Step 2 — Filter client-side

For each supplier returned, check:
```
if iban == null → no IBAN returned; this does not prove there are no bank details (account number, routing number and sort code are write-only and never returned)
if iban != null → IBAN available (can wire)
if bankDetailsUpdatedAt != null while iban == null → bank details were entered but cannot be read here (check in the Spendesk app)
```

Note: non-IBAN details (UK sort code, US routing number, account number) are never returned on read — the `bankInfo` object is write-only. A supplier paid through those details therefore shows `iban` = null.

## Step 3 — Display the report

Display two lists:
1. **Suppliers with no IBAN returned** (iban=null) — name + id — to be checked: they may hold non-IBAN bank details that the MCP does not return
2. **Suppliers with an IBAN** — name + truncated IBAN — ready for wire transfer

Always disclose the scope: *"Based on X active suppliers. Archived suppliers are not included."*

## Step 4 — Use case: supplier follow-up

⚠️ **`get_suppliers` returns no email/contact field at all** (verified live — confirmed by PR #3152, which dropped the "contact details" claim from the tool description since no contact field exists on the read path). No direct email follow-up via this tool.
→ Extract name + id to prepare the follow-up, and find the email through another channel (Spendesk app, or `get_requests` if the IBAN request is tied to an existing request).

## Live example (real data, first page)

- 20 suppliers returned, `hasNextPage=true` (incomplete list)
- 1/20 with an IBAN: +Simple.fr — `FR76151350050008004002...` (truncated for display)
- 19/20 with iban=null — including suppliers like 't Hotel, Oracle (id: 5lwylc0am6e0p7)...

## Example prompt

- "Which suppliers have no IBAN?" → paginate all + filter iban=null
- "List the suppliers we can wire money to" → filter iban != null
- "How many active suppliers have banking details?" → count iban != null on the full list
