API coverage

What this crate wraps of the Invoice Ninja v5 API, and what it doesn't.

Checked against routes/api.php on the v5-stable branch of the invoiceninja repo, which declares 34 Route::resource groups and 274 explicit route declarations (272 single-verb, plus two Route::match pairs registering two verbs each).

Note on sources: Invoice Ninja's published openapi/api-docs.yaml is reliable for schemas but incomplete for routes — it documents /{id} and action paths only for clients, locations, and tags. Use routes/api.php and the controllers when checking whether an endpoint exists or what it returns.

All 34 Route::resource groups are now wrapped, plus users (which is not a resource group). 265 methods in total.

Resources with full CRUD + bulk

30 resources, each with list_*, list_all_*, get_*, create_*, update_*, delete_*, and bulk_*:

Resource	Path	Model
Clients	/clients	Client (+ ClientContact)
Invoices	/invoices	Invoice (+ InvoiceItem)
Quotes	/quotes	Quote (alias of Invoice)
Credits	/credits	Credit (alias of Invoice)
Payments	/payments	Payment (+ PaymentInvoice)
Products	/products	Product
Purchase Orders	/purchase_orders	PurchaseOrder
Recurring Invoices	/recurring_invoices	RecurringInvoice
Recurring Quotes	/recurring_quotes	RecurringQuote (alias of RecurringInvoice)
Recurring Expenses	/recurring_expenses	RecurringExpense
Subscriptions	/subscriptions	Subscription
Projects	/projects	Project
Tasks	/tasks	Task
Task Statuses	/task_statuses	TaskStatus
Expenses	/expenses	Expense
Expense Categories	/expense_categories	ExpenseCategory
Vendors	/vendors	Vendor (+ VendorContact)
Bank Transactions	/bank_transactions	BankTransaction
Tax Rates	/tax_rates	TaxRate
Payment Terms	/payment_terms	PaymentTerm
Webhooks	/webhooks	Webhook
Bank Integrations	/bank_integrations	BankIntegration
Bank Transaction Rules	/bank_transaction_rules	BankTransactionRule
Company Gateways	/company_gateways	CompanyGateway
Designs	/designs	Design
Group Settings	/group_settings	GroupSetting
Locations	/locations	Location
Tags	/tags	Tag
Task Schedulers	/task_schedulers	TaskScheduler
Tokens	/tokens	CompanyToken

bulk_* accepts any action the endpoint supports; archive, restore, and delete work on all of them. An ids list matching nothing returns an empty Vec, not an error.

Resources without a bulk route

Three Route::resource groups have no /bulk route, so they get the six CRUD methods but no bulk_* (which would just 405). These use crud_methods! rather than resource_methods!:

Resource	Path	Model
Client Gateway Tokens	/client_gateway_tokens	ClientGatewayToken
Companies	/companies	Company
System Logs	/system_logs	SystemLog

Company and GroupSetting keep their settings blob as serde_json::Value: CompanySettings is the largest object in the API, and Company itself returns over a hundred fields, so only the structural ones are modeled and extra carries the feature toggles.

Users

/users is not a Route::resource and has no DELETE /users/{id}, so it is hand-written:

Endpoint	Method	Needs password?
GET /users	list_users, list_all_users	no
GET /users/{id}	get_user	yes
POST /users	create_user	yes
PUT /users/{id}	update_user	yes
DELETE /users/{id}/detach_from_company	detach_user_from_company	yes
POST /users/bulk	bulk_users	yes

"Needs password" means the route sits behind the API's password_protected middleware and requires an X-API-PASSWORD header on top of a valid token. Supply it with InvoiceNinjaClient::with_api_password, which also unlocks client and vendor merge, and client/company/user purge. Note that even reading a single user is gated this way.

Entity actions

GET /{resource}/{id}/{action} exists for only four resources — invoices, quotes, credits, and purchase orders. Each gets {singular}_action(id, action) and download_{singular}(id).

Actions returning the entity: auto_bill, clone_to_invoice, clone_to_quote, mark_paid, mark_sent, archive, restore, delete.

Actions that do not return the entity, and so are not usable through *_action:

Action	Returns	Use instead
download	application/pdf stream	download_invoice(id) etc.
convert_to_purchase_order	a purchase order	convert_invoice_to_purchase_order(id)
cancel, history, delivery_note	empty body (upstream quirk)	— not wrapped

Each of the four also gets download_{plural}(&ids) — the bulk download action, which streams one merged PDF. It can't go through bulk_* for the same reason: the response isn't JSON.

Convenience wrappers: mark_invoice_sent and mark_invoice_paid.

Other wrapped endpoints

Endpoint	Method
GET /documents, /documents/{id}	list_documents, list_all_documents, get_document
PUT/DELETE /documents/{id}	update_document, delete_document
GET /documents/{id}/download	download_document → bytes
POST /documents/bulk	bulk_documents
POST /reports/{name}	report(name, body) → raw bytes (CSV for most)
POST /charts/{name}	chart(name, body) → caller-chosen T
POST /search	search(body)
GET /statics	statics()
POST /emails	send_email(body)
POST /payments/refund	refund_payment(body)
GET /ping	ping()
GET /health_check	health_check()

report and chart take the name as a string, so all 32 report and 11 chart endpoints are reachable without a per-endpoint method:

• Reports — activities, ar_detail_report, ar_summary_report, client_balance_report, client_contacts, client_locations, clients, client_sales_report, contacts, credits, documents, expenses, invoice_items, invoices, locations, payments, preview, products, product_sales, profitloss, projects, purchase_order_items, purchase_orders, quote_items, quotes, recurring_invoice_items, recurring_invoices, tasks, tax_period_report, tax_summary_report, user_sales_report, vendors
• Charts — totals, totals_v2, chart_summary, chart_summary_v2, calculated_fields, analytics_summary, analytics_totals, cashflow_forecast, client_payment_analytics, project_analytics, project_burnup

Three of these take a further path segment rather than carrying the id in the body: charts/project_analytics/{project}, charts/project_burnup/{project}, and reports/preview/{hash}. The name argument is interpolated as-is, so pass the whole tail — chart("project_burnup/<id>", &body).

Large report exports are queued and emailed rather than returned inline; in that case the body is a short JSON message instead of CSV.

Not covered

Blocked on a dependency change

Multipart uploads — PUT /{resource}/{id}/upload exists for clients, companies, credits, expenses, group_settings, invoices, payments, products, projects, purchase_orders, quotes, recurring_expenses, recurring_invoices, recurring_quotes, tasks, and vendors. These need reqwest's multipart feature, which isn't currently enabled. This is the main reason Document has no create_document.

Resource groups not wrapped

None — all 34 Route::resource groups are covered.

Adding a new one is mechanical: add a model under src/models/, re-export it from src/models/mod.rs, and add a resource_methods! invocation in src/client.rs (or crud_methods! if the resource has no /bulk route — check routes/api.php).

Password-protected endpoints still unwrapped

with_api_password makes these reachable, but the methods themselves aren't written yet:

• POST /clients/{id}/purge
• POST /clients/{id}/{other}/merge
• POST /vendors/{id}/{other}/merge
• POST /companies/purge/{company}, POST /companies/purge_save_settings/{company}
• POST /users/{id}/invite, POST /users/{id}/purge, GET /users/create

Individual endpoints not wrapped

• Client extras — updateTaxData, show_settings, peppol_discovery, check_vat, vat_status, documents
• Bank integration extras — refresh_accounts, remove_account/{id}, get_transactions/{id}, and POST /bank_transactions/match
• Company gateway extras — test, clone, import_customers
• Company extras — GET /companies/{id}/logo, POST /companies/{id}/default, updateOriginTaxData, POST /companies/current
• Design extras — POST /designs/set/default
• Client gateway token extras — setAsDefault
• Task extras — POST /tasks/sort
• Webhook extras — POST /webhooks/{id}/retry
• Subscription extras — GET /subscriptions/steps, POST /subscriptions/steps/check
• User extras (not password-protected, unlike the rest of /users) — POST /users/{id}/disconnect_mailer, POST /users/{id}/disconnect_oauth, POST /user/{id}/reconfirm
• Preview — POST /preview, POST /preview/purchase_order, live preview
• Activities — GET /activities, POST /activities/entity, POST /activities/notes, download_entity/{activity}
• Email history — POST /emails/clientHistory/{client}, POST /emails/entityHistory
• Auth — /login, /logout, /refresh, /connected_account, passkey routes
• Import/export — /import, /preimport, /import_json, /export, /migration/start
• Invoice extras — delivery_note, payment_schedule, update_reminders
• Public invitation-key downloads — GET /{entity}/{invitation_key}/download for invoice, quote, credit, and purchase_order (note the singular path segment), plus the matching e-invoice variants download_e_invoice, download_e_quote, download_e_credit, download_e_purchase_order. These are invitation-key based and take no auth token, so they don't fit the client's authenticated request path.
• Integrations — Stripe, QuickBooks, Apple in-app purchase, PostMark, einvoice (17 routes), calendar_connection, self-update, templates, hooks, Yodlee (/yodlee/*), Nordigen (/nordigen/institutions)
• Misc — /company_users, /company_ledger, /client_statement, /claim_license, /check_license, /check_subdomain, /one_time_token, /last_error, /support/messages/send, /verify/*, /accounts/{id}, /feedback, /filters/{entity}, /scheduler, /mailer/check, /smtp/check, /password_timeout, /refresh_react, /webcron, /token_hash_router, /reactivate_email/{bounce_id}, /protected_download/{hash}, /confirm_purchase, /exports/preview/{hash}, /templates/preview/{hash}

Typed response gaps

statics, chart, search, send_email, and health_check are generic over T: DeserializeOwned rather than returning concrete structs, because none of them has a stable published schema. Pass serde_json::Value, or your own struct to pin the parts you rely on.

Compared with the official PHP SDK

invoiceninja/sdk-php is the first-party wrapper. It's worth checking against, but it is deliberately thinner than this crate: every one of its endpoint classes is just a URI on top of a shared BaseEntity offering all, get, create, update, bulk, archive, delete, restore, and download. Only Companies and Statics add anything of their own.

It covers nothing we don't. The five resources it used to have on us — users, companies, group_settings, bank_integrations, client_gateway_tokens — are all wrapped now.

We cover a lot it doesn't: payment_terms, task_statuses, recurring_quotes, recurring_expenses, bank_transaction_rules, company_gateways, designs, locations, tags, task_schedulers, tokens, system_logs, documents, per-entity actions (mark_sent, mark_paid, clone_to_*, …), per-entity PDF download, reports, charts, search, send_email, refund_payment, ping, health_check, automatic pagination (list_all_*), and X-API-PASSWORD support for the password-protected routes.

Deliberate differences in behaviour:

	PHP SDK	This crate
Request bodies	form_params (urlencoded)	JSON
Base URL	host only; appends /api/v1 itself	full API root, or hosted()
Single-entity delete	none — delete() is bulk	delete_*(id) via HTTP DELETE, plus bulk_*
Validation errors	surfaces only the first message	whole per-field errors map on Error::Api
List filters	arbitrary array	typed setters plus ListParams::param

The urlencoded-vs-JSON difference is the one that matters: form encoding bracket-encodes nested structures, so a payload like an invoice's line_items array of objects is far cleaner as JSON. Both are accepted by the API.

Two things in the PHP SDK are not worth copying: it sends stream: false in download payloads, but no controller reads a stream input, and its BaseEntity::download is available on every resource even though only PDF-rendering entities support the action.
