description

Send registered (LREL) or priority (LEL) French postal mail via laposte.fr from the terminal using `laposte_cli`. Use when the user wants to send a paper letter, a recommandé/AR, an e-lettre rouge, or upload one or more PDFs for La Poste to print + distribute. The CLI uploads PDF(s), RNVP-certifies recipient address(es), creates a cart entry, then opens https://www.laposte.fr/checkout/recapitulatif so the user can confirm payment in the browser with a saved card. Cookies are read live from the user's browser — no manual paste, no API key.

laposte-cli

CLI on top of laposte.fr's "Courrier En Ligne" (CEL) back-end. PDF only. Handoff payment — the CLI never sees or transmits card data; it stops at the payment page and the user clicks Payer themselves.

When to use

"envoie cette lettre en recommandé à X"
"fais-moi un envoi postal de ces 3 PDF pour mon notaire"
"génère un recommandé avec AR pour ce courrier"
"envoie ça en e-lettre rouge demain"

When NOT to use

The user has only text (no PDF). The website's "Rédiger un texte" mode is broken as of 2026-05-13 and the CLI doesn't support it. Render the text to PDF first (e.g. via pandoc, libreoffice, or weasyprint), then upload.
The user wants the CLI to pay automatically. V1 is handoff only — payment lives in the browser. Do not attempt to bypass this.

Usage by an agent

1. Verify login state

Before anything, run:

laposte-cli whoami

If it returns a User ID: line, the user is logged in and the CLI can read cookies from their browser. If it errors with "Not logged in", the user needs to:

Open https://www.laposte.fr in Chrome (or another supported browser: firefox/safari/edge/brave/chromium/opera/arc) and log in.
Run laposte-cli login --browser <name> once. On macOS Chrome the first read may pop a Keychain prompt — the user accepts it once.

whoami after that should succeed. Agents should not try to bypass this step — there is no API key.

2. List sender addresses (optional, for `--from`)

laposte-cli addresses

Prints a table of the user's saved postal addresses with their IDs and labels. Useful for picking --from <label> (otherwise the primary address is used).

3. Send

laposte-cli send <pdf> [<pdf>...] --to "Civ Prenom Nom|street|CP VILLE" [options]

Required:

One or more PDF paths (positional, repeatable). Max 20 Mo per PDF.
One or more --to flags. The pipe | is the field separator. Format: "M Jean Dupont|1 rue de la Paix|75001 PARIS". Civility is M or MME (defaults to M if missing). Up to 100 recipients per letter.

Format / options:

--format recommande (default, LREL) | lettre-rouge (LEL, J+1).
--ar — avis de réception (LREL only, +1,25 €).
--tracking — postal tracking (LEL only, +0,50 €).
--color / --bw — color print (+0,50 €) or B&W (default).
--duplex / --simplex — recto-verso (default) or recto only.
--from <id-or-label> — sender address, default = primary.
--no-sender — omit the return address.
--date DD/MM/YYYY — deposit date, default = today.
--dry-run — upload + price only, don't create the cart.
--no-open — print the checkout URL but don't open it in a browser.

Example: registered letter with AR (recipient provided by the user)

laposte-cli send acte.pdf annexes.pdf \
  --to "<civility> <First> <Last>|<street>|<cp> <city>" \
  --format recommande --ar

Example: e-lettre rouge with tracking, batch send

laposte-cli send invoice.pdf \
  --to "<civility> <First> <Last>|<street>|<cp> <city>" \
  --to "<civility> <First> <Last>|<street>|<cp> <city>" \
  --format lettre-rouge --tracking

Expected output (success path)

From: <label> — <street> <cp> <city>
Resolving 1 recipient(s)…
  → <FULL NAME> — <street> <cp> <city> (ceaid=<10-char-RNVP-code>)
Uploading 1 PDF(s)…
  → acte.pdf (4 page(s), id=<doc-uuid>)
Draft id: <sending-uuid>…
Tarif : 8,60 € (8.596 EUR)
Creating cart entry (server is generating PDFs, ~5s)…
✓ Cart entry created (?).

Pay here: https://www.laposte.fr/checkout/recapitulatif

After this the user must visit (or have their browser opened to) that URL and click Payer with one of their saved cards. The CLI's job is done.

Failure modes

Symptom	What it means	Action
`Not logged in`	No supported browser session found	Tell user to log in to laposte.fr in their browser, then `laposte-cli login --browser <name>`
`SERCADIA could not RNVP-certify`	The recipient address is not in La Poste's database	Recheck the spelling; try with the official postal address
`Price calc failed: 500 ... sheetsCount null`	We forgot to populate page metrics	Bug — file an issue. Should not happen for PDF input.
`Cart creation failed: 400 ... recipientId`	/recipients endpoint refused our shape	Re-check the `--to` syntax; report the address that failed
HTTP 503 Backend fetch failed (Varnish)	Transient La Poste hiccup	Just retry
`Upload failed: 400 ... SENDING_NOT_FOUND`	sendingId out of sync	Should self-recover; re-run

After sending

The cart sticks around for ~24h in https://www.laposte.fr/checkout/recapitulatif. If the user wants to cancel a queued cart, they can empty it in the browser (no CLI command for that yet — V3 territory).

Architecture (for maintenance)

Step	Endpoint
Auth	`browser_cookie3.chrome(domain_name="laposte.fr")` — read live every call
Sender list	`GET /cel/address/lpelPart/account/profiles/CURRENT/postal-addresses`
RNVP cert	`GET /cel/address/sercadia/check?streetName=&place={CP}+{VILLE}`
Wipe draft	`DELETE /cel/sending/lpelPart/{userId}`
Upload	`POST /cel/occ/.../e-service/cel/upload` (multipart, omit sendingId on first call)
Sync state	`POST /cel/sending/lpelPart/{userId}` (full draft JSON)
Recipients	`POST /cel/occ/.../e-service/cel/recipients` `{addresses, sendingId, postageType}`
Price	`POST /cel/occ/.../e-service/cel/price` (celConfigurationWsDTO + sheetsCount)
Cart	`POST /cel/occ/.../e-service/cel/users/current/carts/current` (addEServiceToCart item)

Gotchas worth knowing:

The CEL API uses postal line-number address naming (line1 = street, town, postalCode, country: {isocode}, ceaId capital I, titleCode: "mr"/"mrs" + title: "M."/"Mme"). The translation lives in _to_api_address() in the script.
lpel_ftid_cel_part / lpel_ftid_chkt_part / lpel_ftid_ecom_part share a UUID — only the prefix differs.
The lpel_cel cookie tracks the active server-side draft; the CLI ignores it and lets /upload allocate a fresh one each run.

Don't

Don't try to also drive the payment from the CLI. Tell the user the payment is in their browser.
Don't paste cookies for the user from logs/transcripts; cookies rotate and they're in the user's browser already.
Don't reuse old sendingId across runs — let the server allocate.
