n8n-nodes-morning

n8n community node for Morning (formerly Green Invoice / חשבונית ירוקה) — the Israeli accounting and invoicing API.

Full coverage of the API surfaces a real workflow needs: documents, clients, suppliers, items, expenses, accounting classifications, business profile, and the hosted-checkout payment flow with auto-issued tax invoice + receipt. Includes a trigger node that receives Morning's notifyUrl webhooks.

Built against the live sandbox API (verified 2026-05-31).

Recurring Payment and Retainer wrap Morning's recurring-income features (הכנסות קבועות). A Recurring Payment (/payments/recurrings) auto-charges a saved credit-card token on a schedule; a Retainer (/retainers) auto-issues a recurring document/payment-request to a client. These two endpoint families are not in Morning's official (Apiary) API reference — paths, verbs, bodies and enums were taken verbatim from Morning's own web-app client (and confirmed against a live recurring-payment response).

Note the two resources use different interval encodings: Recurring Payment is 1 / 2 / 3 / 12 (months); Retainer is 1m / 2m / 3m / 6m / 1y. Status filters are numeric: recurring 5/10/20/30/50/60/70 (pending/created/started/finished/canceled/suspended/expired), retainer 1/2/3/10/20 (created/started/finished/paused/deleted).

The retainer create/update body is nested (from the web app's buildData()): { startDate, endDate, interval, doc: { …document fields, type }, data: { paymentTerms, description } }, built via dotted properties (doc.*, data.*). paymentTerms is a number (Immediate -1, or Net 10/15/30/45/60/75/90/120); data.description is a token (my = month-year, pmy = previous-month-year) or free text.

Transaction (/payments/transactions) reads and reverses the actual charge records behind payment forms, token charges and recurring runs — the counterpart to Payment, which creates the checkout links/forms/tokens. Search takes { documentId, from, to, page, pageSize } (dates YYYY-MM-DD) and returns a paged items[] with aggregations; Get additionally returns the full paymentData (card number/expiry/token) that Search omits. Cancel (/cancel, no body) fully voids a still-cancellable charge; Refund (/refund, body { amount } — omit for a full refund) returns money on a settled one. Both produce a new, linked reversal transaction (type: 25, negative amount, relatedTransactionId → the original). Only rows with cancellable: true can be voided. Paths/verbs were taken verbatim from Morning's own web-app payment service.

Document → Create's "Enable Online Payment" attaches an online payment link (credit card / Bit / Apple Pay / Google Pay) directly to the document being created — the same one-call flow Morning's own web app uses when you toggle online payment on a Tax Invoice. It sends paymentRequestData: { plugins: [{ id: pluginId, type: 12200, group }, ...], maxPayments } in the same POST /documents body (not a separate /payments/form call); the response carries a paymentRequestId, and once the customer pays, Morning auto-issues a linked receipt and closes the document. This is distinct from Payment → Create Payment Form, which always creates a brand-new combo document (320/400/405) from scratch rather than attaching a payment link to an existing/being-created document. Undocumented in Morning's Apiary reference — reverse-engineered from a live sandbox request captured from the web app's network traffic.

Trigger: Morning Trigger

• Receives the form-urlencoded webhook Morning POSTs to notifyUrl after a payment
• Optional ?token= query-param verification (Morning does not sign webhooks, so this is the recommended guard)
• Output: parsed (camelCase normalized) or raw

Built-in helpers (so you don't trip on Morning's gotchas)

• Israeli mod-10 (Luhn-variant) checksum validates taxId on client/supplier create before the request goes out. Rejects "123456789" with a clear error instead of waiting for Morning's Hebrew rejection. Test value 000000018 passes.
• VAT math auto-compute (Payment → Create Payment Form): toggle "Auto-Compute Amount from Income" and the node calculates amount from income[] × vatRate per the chosen vatType. No more קיים חוסר התאמה בין סכום התקבולים לסכום התשלומים errors.

Install

Community Nodes panel (easiest — self-hosted n8n)

1. In n8n: Settings → Community Nodes → Install.
2. Enter the package name n8n-nodes-morning and confirm.
3. The Morning and Morning Trigger nodes appear in the node panel.

Requires self-hosted n8n with community packages enabled (N8N_COMMUNITY_PACKAGES_ENABLED=true, which is the default). n8n Cloud only lists verified community nodes in the panel.

npm (Docker / manual)

cd ~/.n8n/custom        # mkdir -p ~/.n8n/custom first if it doesn't exist
npm install n8n-nodes-morning
# restart n8n

From source (development)

git clone https://github.com/shirser121/n8n-nodes-morning.git
cd n8n-nodes-morning
npm install
npm run build
cd ~/.n8n/custom && npm install /absolute/path/to/n8n-nodes-morning
# restart n8n

The Morning node and Morning Trigger appear in the node panel.

Getting started

1. Generate API keys at app.greeninvoice.co.il → המשתמש שלי → כלי מפתחים → API Keys (separate tabs for sandbox vs production).
2. Create the credential in n8n: paste id, secret, pick environment. Hit "Test" — it should green-check against /businesses/me.
3. Discover your pluginId — drop a Morning node, Resource: Document, Operation: Get Info, Type: 320. The response contains paymentPlugins[0].id — that's your pluginId for any payment-form call.
4. Build the payment flow:
   • Morning node → Resource: Payment → Op: Create Payment Form. Paste the pluginId. Set notifyUrl to the URL of your Morning Trigger node.
   • Morning Trigger node → set a verification token, append ?token=<value> to the URL you paste into notifyUrl.
   • Customer redirected to response.url from Create Payment Form → pays → Morning issues a tax invoice + receipt → webhook fires → workflow continues.

Gotchas built into the node (so you don't trip on them)

• Field naming is non-obvious. The node uses Morning's exact names: income (not items), payment singular (not payments), emails always array (not email), lang (not language), remarks (not notes).
• VAT math — amount must match income[] based on vatType. The Auto-Compute toggle on payment-form does this for you. Manual math also works — the VAT-type dropdown spells out which mode means what.
• Documents are immutable — there is no Update operation on Document, because Morning returns 405. To fix an issued doc, create a credit note (type 330) with linkedDocumentIds, then issue a new one.
• Clients/suppliers with docs/expenses can't be deleted — set active: false instead (via Update).
• taxId must pass Israeli mod-10 checksum. The node validates this client-side. Test value: 000000018.
• Expense documentType — use the supplier's invoice kind (305/320/400), NOT 10 (quote). The dropdown only shows valid options.
• Expense number — must be ≥5 numeric digits. "INV-001" and "1001" are both rejected.
• accountingClassification — pass the UUID id from /accounting/classifications/map, not the code or key. Use Resource: Accounting → Get Classifications Map to discover.
• Rate limit ~3 req/s — n8n batches don't throttle by default. For high-volume workflows, add a Wait node.

Webhook security

Morning does not sign webhooks. Anything that knows your notifyUrl can forge a "paid" callback. Two guards:

1. Use the trigger's "Verification Token (Query Param)" — append ?token=<long-random> to the URL you give Morning. The node rejects anything without a match.
2. The trigger output's documentId is Morning's UUID. After receiving, use a Morning action node with Op: Get Document to fetch the canonical document — if the doc id is bogus, it 404s and you abort.

Notes for production

• The session token is cached for ~50 minutes (TTL is 60). The expirable: true flag on the credential's session token field tells n8n to re-call preAuthentication when needed.
• The notifyUrl callback comes from AWS eu-west-1 (34.255.212.236 observed) with User-Agent: GreenInvoice/2.1.
• Body is application/x-www-form-urlencoded — n8n parses it automatically into req.body.
• Be idempotent on documentId — Morning may retry on 5xx/timeout.
• Return 2xx fast (≤5s). Do heavy work async via a follow-on workflow.

dist/ is git-ignored and produced at build/publish time. Cutting a GitHub Release publishes the package to npm automatically (see .github/workflows/publish.yml).

For the n8n verified community-node badge, switch linting over to eslint-plugin-n8n-nodes-base (see the note in .eslintrc.js) and clear its findings before submitting to n8n.
