Requirements

Installation

You can install the package via Composer:

composer require yehia-tarek/laravel-erpnext

Publish the configuration file to define your ERPNext connection settings:

php artisan vendor:publish --tag="erpnext-config"

Configuration

Add your ERPNext credentials to your application's .env file. The package supports multiple authentication methods, with Token Authentication being the recommended approach for API integrations.

ERPNEXT_BASE_URL=https://mycompany.erpnext.com

# --- Token Auth (Recommended) ---
ERPNEXT_AUTH_METHOD=token
ERPNEXT_API_KEY=your_api_key
ERPNEXT_API_SECRET=your_api_secret

# --- Password Auth (Session-based) ---
# ERPNEXT_AUTH_METHOD=password
# ERPNEXT_USERNAME=admin
# ERPNEXT_PASSWORD=secret

# --- OAuth 2.0 ---
# ERPNEXT_AUTH_METHOD=oauth
# ERPNEXT_ACCESS_TOKEN=your_bearer_token

# --- HTTP Options ---
ERPNEXT_TIMEOUT=30
ERPNEXT_VERIFY_SSL=true

Generating API Keys in ERPNext

To use Token Authentication, generate API keys from your ERPNext instance:

1. Go to User List → open the desired user.
2. Click on the Settings tab.
3. Expand the API Access section and click Generate Keys.
4. Copy the API Secret immediately (it is only shown once).
5. Note the API Key displayed in the same section.

Authentication

The package automatically handles authentication based on your .env configuration.

• Token: Sends Authorization: token {api_key}:{api_secret} with every request.
• Password: Performs a login request on the first API call and reuses the returned cookie session for subsequent requests.
• OAuth 2.0: Sends Authorization: Bearer {access_token} with every request.

Quick Start

After configuring your .env file, you can verify the connection using the ERPNext facade:

use YehiaTarek\ERPNext\Facades\ERPNext;

$user = ERPNext::getLoggedUser(); 
// Returns: "admin@example.com"

Usage

CRUD Operations

The package provides intuitive methods to interact with ERPNext documents.

Create a Document

$invoice = ERPNext::createDocument('Sales Invoice', [
    'customer' => 'ACME Corp',
    'items'    => [
        ['item_code' => 'ITEM-001', 'qty' => 2, 'rate' => 150],
    ],
]);

echo $invoice['name']; // e.g., "SINV-00001"

Read a Document

$invoice = ERPNext::getDocument('Sales Invoice', 'SINV-00001');
echo $invoice['grand_total'];

// Expand link fields to fetch full related documents instead of just their names
$expandedInvoice = ERPNext::getDocument('Sales Invoice', 'SINV-00001', expandLinks: true);
echo $expandedInvoice['customer']['customer_name']; // Returns the full Customer document

Update a Document

ERPNext::updateDocument('Sales Invoice', 'SINV-00001', [
    'status' => 'Paid',
]);

Delete a Document

ERPNext::deleteDocument('Sales Invoice', 'SINV-00001'); // Returns true on success

Fluent Query Builder

Retrieve multiple documents using a fluent, Eloquent-like query builder that wraps the GET /api/resource/:doctype endpoint.

use YehiaTarek\ERPNext\Facades\ERPNext;

$invoices = ERPNext::query('Sales Invoice')
    ->fields(['name', 'customer', 'grand_total', 'status'])
    ->filter('status', '=', 'Paid')
    ->filter('grand_total', '>', 5000)
    ->orderBy('grand_total', 'desc')
    ->limit(25)
    ->get(); // Returns an array of arrays

Available Builder Methods

Supported Filtering Operators

->filter('status', '=',      'Paid')
->filter('amount', '>',      1000)
->filter('amount', '>=',     500)
->filter('name',   'like',   'SINV-%')
->filter('status', 'in',     ['Paid', 'Unpaid'])
->filter('status', 'not in', ['Cancelled'])
->filter('note',   '!=',     null)

Remote Method Calls

Call any whitelisted Python method on your ERPNext instance.

// GET method (read-only)
$user = ERPNext::callGet('frappe.auth.get_logged_user');

// POST method (mutates data)
ERPNext::callPost('frappe.client.submit', [
    'doc' => ['doctype' => 'Sales Invoice', 'name' => 'SINV-00001'],
]);

// Generic call specifying the HTTP verb explicitly
ERPNext::call('erpnext.accounts.doctype.payment_entry.payment_entry.get_outstanding_reference_documents', [
    'args' => ['party_type' => 'Customer', 'party' => 'CUST-001'],
], 'POST');

File Uploads

Upload files directly from your local filesystem or via raw content.

Upload from Local Path

$file = ERPNext::uploadFile(
    filePath: storage_path('app/invoice.pdf'),
    doctype:  'Sales Invoice',
    docname:  'SINV-00001',
    fieldname: 'attachment',
    isPrivate: true,
);

echo $file['file_url'];

Upload from Raw Content

$file = ERPNext::uploadFileContent(
    content:  $pdfContent,
    filename: 'report.pdf',
    doctype:  'Sales Invoice',
    docname:  'SINV-00001',
);

Advanced Features

Typed Document Resources

For a more structured, object-oriented approach, you can define typed resources that extend the base Document class. This provides an Eloquent-like experience for specific DocTypes.

namespace App\ERPNext;

use YehiaTarek\ERPNext\Resources\Document;

class SalesInvoice extends Document
{
    protected static string $doctype = 'Sales Invoice';
}

Usage Example:

use App\ERPNext\SalesInvoice;

// Query
$paid = SalesInvoice::query()
    ->fields(['name', 'customer', 'grand_total'])
    ->filter('status', '=', 'Paid')
    ->orderBy('modified', 'desc')
    ->get();

// Find
$invoice = SalesInvoice::find('SINV-00001');
echo $invoice->grand_total;

// Find or fail (throws DocumentNotFoundException)
$invoice = SalesInvoice::findOrFail('SINV-00001');

// Create
$invoice = SalesInvoice::create([
    'customer' => 'ACME Corp',
    'items'    => [...],
]);

// Update (partial)
$invoice->update(['status' => 'Paid']);

// Save (create or update based on whether 'name' is present)
$invoice = new SalesInvoice(['customer' => 'ACME Corp', ...]);
$invoice->save();

// Delete & Refresh
$invoice->delete();
$invoice->refresh();

Multiple Connections

If you need to interact with multiple ERPNext instances (e.g., staging and production), define them in config/erpnext.php:

return [
    'base_url' => env('ERPNEXT_BASE_URL'),
    'auth'     => [...],
    'connections' => [
        'staging' => [
            'base_url' => env('ERPNEXT_STAGING_URL'),
            'auth'     => [
                'method'     => 'token',
                'api_key'    => env('ERPNEXT_STAGING_API_KEY'),
                'api_secret' => env('ERPNEXT_STAGING_API_SECRET'),
            ],
        ],
    ],
];

You can easily switch connections using the connection() method:

$stagingInvoice = ERPNext::connection('staging')->getDocument('Sales Invoice', 'SINV-00001');

Error Handling

The package throws specific exceptions for different API error scenarios, allowing you to handle them gracefully.

Example:

use YehiaTarek\ERPNext\Exceptions\DocumentNotFoundException;
use YehiaTarek\ERPNext\Exceptions\ValidationException;
use YehiaTarek\ERPNext\Exceptions\ERPNextException;

try {
    $doc = ERPNext::getDocument('Sales Invoice', 'SINV-GHOST');
} catch (DocumentNotFoundException $e) {
    // Handle 404
} catch (ValidationException $e) {
    $context = $e->getContext(); // Raw response body as array
} catch (ERPNextException $e) {
    // Handle generic API errors
}

Testing

Run the package tests using Composer:

composer test

Mocking in Your Application Tests

You can easily mock the ERPNext facade in your application's test suite:

use YehiaTarek\ERPNext\Facades\ERPNext;

ERPNext::shouldReceive('getDocument')
    ->with('Sales Invoice', 'SINV-00001', false)
    ->andReturn(['name' => 'SINV-00001', 'status' => 'Paid']);
