README

A comprehensive Laravel wrapper for the Pennylane API v2. Covers all ~127 endpoints with typed Response DTOs, cursor-based pagination, OAuth 2.0 support, and automatic retry.

Built on Laravel's HTTP client (Illuminate\Http\Client).

Requirements: PHP 8.1+, Laravel 8+

Installation

composer require c-delouvencourt/laravel-pennylane

Publish the configuration file:

php artisan vendor:publish --provider="CLDT\PennylaneLaravel\PennylaneLaravelServiceProvider" --tag="config"

Authentication

Bearer token (default)

PENNYLANE_API_KEY=your_api_key

OAuth 2.0

PENNYLANE_AUTH_METHOD=oauth2
PENNYLANE_OAUTH_CLIENT_ID=your_client_id
PENNYLANE_OAUTH_CLIENT_SECRET=your_client_secret
PENNYLANE_OAUTH_REDIRECT_URI=https://your-app.com/callback
PENNYLANE_OAUTH_TOKEN=your_access_token
PENNYLANE_OAUTH_REFRESH_TOKEN=your_refresh_token

Retry

All HTTP requests are automatically retried on recoverable failures (5xx server errors, 429 rate limiting, and connection timeouts). Client errors (400, 401, 403, 404, 422) are not retried since they would never succeed. You can configure this behavior via environment variables:

PENNYLANE_RETRY_TIMES=3      # Number of attempts (default: 3)
PENNYLANE_RETRY_SLEEP=500     # Delay in ms between attempts (default: 500)
PENNYLANE_RETRY_THROW=true    # Throw exception after all attempts fail (default: true)

Or directly in config/pennylane-laravel.php:

'retry' => [
    'times' => 3,
    'sleep' => 500,
    'throw' => true,
],

Error Handling

All API calls throw typed exceptions on failure. Every exception extends PennylaneApiException, so you can catch specific errors or handle them all at once:

use CLDT\PennylaneLaravel\Exceptions\PennylaneApiException;
use CLDT\PennylaneLaravel\Exceptions\PennylaneNotFoundException;
use CLDT\PennylaneLaravel\Exceptions\PennylaneBadRequestException;
use CLDT\PennylaneLaravel\Exceptions\PennylaneAuthenticationException;

try {
    $invoice = $pennylane->customerInvoices()->get(999);
} catch (PennylaneNotFoundException $e) {
    // 404 — resource not found
    $e->getStatusCode();    // 404
    $e->getErrorMessage();  // Error message from the API
    $e->getResponseBody();  // Full decoded JSON response
} catch (PennylaneBadRequestException $e) {
    // 400 — includes structured error details
    $e->getField();          // ?string — the field that caused the error
    $e->getBadRequestCode(); // ?BadRequestCode enum — e.g. BadRequestCode::NotExistRequiredKey
    $e->getPayload();        // ?string
} catch (PennylaneAuthenticationException $e) {
    // 401 — invalid or missing token
} catch (PennylaneApiException $e) {
    // Catch-all for any other API error (403, 422, 429, 5xx...)
    $e->getStatusCode();
    $e->getErrorMessage();
}

Exception hierarchy:

Exception	HTTP Status
`PennylaneBadRequestException`	400
`PennylaneAuthenticationException`	401
`PennylaneAuthorizationException`	403
`PennylaneNotFoundException`	404
`PennylaneValidationException`	422
`PennylaneRateLimitException`	429
`PennylaneServerException`	5xx
`PennylaneApiException`	Any other non-2xx

All exceptions provide: getStatusCode(), getErrorMessage(), getResponseBody(), getResponse().

Usage

All methods return typed Response DTOs with readonly properties. List endpoints return a PaginatedResponse with cursor-based pagination.

Pagination

use CLDT\PennylaneLaravel\PennylaneLaravel;

$result = app(PennylaneLaravel::class)->customers()->list();

$result->items;       // array of CustomerResponse
$result->has_more;    // bool
$result->next_cursor; // ?string

// Fetch next page
$nextPage = app(PennylaneLaravel::class)->customers()->list(['cursor' => $result->next_cursor]);

Migrating from v2.0 to v2.1

HTTP client

The underlying HTTP client has been migrated from GuzzleHTTP to Laravel's HTTP facade (Illuminate\Http\Client). This change is transparent for most usages, but if you were injecting GuzzleHttp\ClientInterface directly, you need to update to Illuminate\Http\Client\PendingRequest.

File uploads

The import() and upload() methods now use multipart/form-data and accept two parameters instead of one:

Method	Before	After
`customerInvoices()->import()`	`import(array $data)`	`import(array $fields = [], array $attachments = [])`
`customerInvoices()->uploadAppendix()`	`uploadAppendix(int $id, array $data)`	`uploadAppendix(int $id, array $fields = [], array $attachments = [])`
`supplierInvoices()->import()`	`import(array $data)`	`import(array $fields = [], array $attachments = [])`
`fileAttachments()->upload()`	`upload(array $data)`	`upload(array $fields = [], array $attachments = [])`
`ledgerAttachments()->upload()`	`upload(array $data)`	`upload(array $fields = [], array $attachments = [])`
`eInvoices()->import()`	`import(array $data)`	`import(array $fields = [], array $attachments = [])`

Each attachment is an array with the following keys:

['name' => 'file', 'contents' => $fileContents, 'filename' => 'invoice.pdf']

Error handling

API errors now throw typed exceptions (PennylaneApiException and subclasses) instead of silently returning partial data. If your code relied on checking response arrays for errors, wrap your calls in try/catch blocks instead. See the Error Handling section.

Retry

Automatic retry is now configured by default (3 attempts, 500ms delay) and only retries recoverable errors (5xx, 429, connection failures). Client errors (4xx) are thrown immediately. See the Retry section to customize.

Dependencies

Removed: guzzlehttp/guzzle
Added: illuminate/http

Migrating from v1 to v2

v1	v2	Notes
`invoices()`	`customerInvoices()`	`invoices()` still works as deprecated alias
`estimates()`	`quotes()`	`estimates()` still works as deprecated alias
`enums()->get('unit')`	Removed	Use PHP enums in `Dto\Enums\*` instead
Array returns	DTO returns	All methods return typed Response DTOs
Offset pagination	Cursor pagination	Use `PaginatedResponse` with `next_cursor`
`PENNYLANE_API_KEY`	`PENNYLANE_API_KEY`	Same env var, new config structure

Response DTOs

All responses use readonly properties and can be created from arrays:

use CLDT\PennylaneLaravel\Dto\Responses\ProductResponse;

$product = $pennylane->products()->get('1');
$product->id;                // int
$product->label;             // string
$product->price_before_tax;  // ?string
$product->currency;          // ?string
$product->created_at;        // ?string

PHP Enums

All API enum values are available as PHP 8.1 backed enums:

use CLDT\PennylaneLaravel\Dto\Enums\InvoiceStatus;
use CLDT\PennylaneLaravel\Dto\Enums\Currency;
use CLDT\PennylaneLaravel\Dto\Enums\VatRate;
use CLDT\PennylaneLaravel\Dto\Enums\PaymentConditions;

InvoiceStatus::Draft->value;          // 'draft'
Currency::EUR->value;                 // 'EUR'
VatRate::FR200->value;                // 'FR_200'
PaymentConditions::Days30->value;     // '30_days'

Available enums: AccountType, BadRequestCode, BillingSubscriptionMode, BillingSubscriptionOccurrenceRuleType, BillingSubscriptionPaymentMethod, BillingSubscriptionStatus, CategoryDirection, CommercialDocumentType, Currency, CustomerBillingLanguage, DiscountType, ExportStatus, InvoiceAccountingStatus, InvoicePaymentStatus, InvoiceStatus, MandateStatus, PaymentConditions, PaymentStatus, ProductUnit, PurchaseRequestStatus, QuoteStatus, SepaSequenceType, SupplierDueDateRule, SupplierPaymentMethod, VatRate.
