Quick Start

use Nusii\Nusii;

$nusii = new Nusii('your-api-key');

// List your clients
$clients = $nusii->clients()->list();

foreach ($clients as $client) {
    echo $client['name'] . "\n";
}

Custom Base URL

For self-hosted or development environments:

$nusii = new Nusii('your-api-key', baseUrl: 'http://localhost:3000');

Sections

// List all sections
$sections = $nusii->sections()->list();

// List sections for a specific proposal
$sections = $nusii->sections()->list(proposalId: 456);

// List sections for a specific template
$sections = $nusii->sections()->list(templateId: 789);

// Include line items in the response
$sections = $nusii->sections()->list(proposalId: 456, includeLineItems: true);

// Get a single section
$section = $nusii->sections()->get(10);

// Create a section
$section = $nusii->sections()->create([
    'proposal_id' => 456,
    'title' => 'Project Scope',
    'body' => '<p>Detailed project scope description.</p>',
    'position' => 1,

    'title' => 'Updated Section Title',
    'body' => '<p>Updated content.</p>',
]);

// Delete a section
$nusii->sections()->delete(10);

Line Items

Line items belong to sections. They must be created under a section.

// List line items for a section
$items = $nusii->lineItems()->listBySection(sectionId: 10);

// Get a single line item
$item = $nusii->lineItems()->get(50);

// Create a line item for a section
$item = $nusii->lineItems()->createForSection(sectionId: 10, attributes: [
    'name' => 'Design Work',
    'quantity' => 10,
    'amount' => 7500,          // in cents
    'cost_type' => 'fixed',    // "fixed" or "hourly"
    'per_type' => 'hour',
    'position' => 1,
]);

// Update a line item
$item = $nusii->lineItems()->update(50, [
    'name' => 'Updated Design Work',
    'quantity' => 20,
]);

// Delete a line item
$nusii->lineItems()->delete(50);

Templates

Templates are read-only.

// List templates
$templates = $nusii->templates()->list();

// Get a single template
$template = $nusii->templates()->get(5);

echo $template['name'];  // "Web Project Template"

Proposal Activities

Proposal activities are read-only and track events like views, accepts, and rejections.

// List all activities
$activities = $nusii->proposalActivities()->list();

// Filter by proposal
$activities = $nusii->proposalActivities()->list(proposalId: 456);

// Filter by client
$activities = $nusii->proposalActivities()->list(clientId: 123);

// Get a single activity
$activity = $nusii->proposalActivities()->get(1);

echo $activity['activity_type'];    // "viewed", "accepted", "rejected"
echo $activity['proposal_title'];   // "Website Redesign"
echo $activity['client_email'];     // "john@example.com"

Users

Users are read-only.

// List users on the account
$users = $nusii->users()->list();

foreach ($users as $user) {
    echo $user['email'];
    echo $user['name'];
}

Themes

Themes are read-only. Note: this endpoint returns a plain array, not a paginated response.

// List available themes
$themes = $nusii->themes()->list();

foreach ($themes as $theme) {
    echo $theme['id'];
    echo $theme['name'];  // "Classic", "Modern", etc.
}

Webhook Endpoints

// List webhook endpoints
$webhooks = $nusii->webhookEndpoints()->list();

// Get a single webhook endpoint
$webhook = $nusii->webhookEndpoints()->get(1);

// Create a webhook endpoint
$webhook = $nusii->webhookEndpoints()->create([
    'target_url' => 'https://example.com/webhooks/nusii',
    'events' => [
        'proposal_created',
        'proposal_accepted',
        'proposal_rejected',
        'proposal_sent',
    ],
]);

// Delete a webhook endpoint
$nusii->webhookEndpoints()->delete(1);

Available webhook events:

Pagination

All list endpoints return a PaginatedResponse object that is both countable and iterable:

$response = $nusii->clients()->list(page: 1, perPage: 10);

// Pagination metadata
$response->currentPage;   // 1
$response->nextPage;      // 2 (or null)
$response->prevPage;      // null (or int)
$response->totalPages;    // 5
$response->totalCount;    // 42

// Navigation helpers
$response->hasNextPage(); // true
$response->hasPrevPage(); // false

// Iterate directly
foreach ($response as $item) {
    echo $item['name'];
}

// Count
echo count($response); // items on current page

// Access raw data array
$response->data; // array of items

Paginating Through All Results

$page = 1;

do {
    $response = $nusii->clients()->list(page: $page, perPage: 50);

    foreach ($response as $client) {
        // Process each client
    }

    $page++;
} while ($response->hasNextPage());

Error Handling

The library throws specific exceptions for different HTTP error codes:

use Nusii\Exceptions\AuthenticationException;
use Nusii\Exceptions\NotFoundException;
use Nusii\Exceptions\ValidationException;
use Nusii\Exceptions\RateLimitException;
use Nusii\Exceptions\ServerException;
use Nusii\Exceptions\NusiiException;

try {
    $client = $nusii->clients()->get(99999);
} catch (AuthenticationException $e) {
    // 401 - Invalid API key
    echo $e->getMessage();
} catch (NotFoundException $e) {
    // 404 - Resource not found
    echo $e->getMessage();
} catch (ValidationException $e) {
    // 400, 403, 422 - Validation or permission errors
    echo $e->getMessage();
    echo $e->getCode();          // HTTP status code
    print_r($e->responseBody);   // Raw response body
} catch (RateLimitException $e) {
    // 429 - Rate limit exceeded (100 requests per 30 seconds)
    echo $e->retryAfter;         // Seconds to wait before retrying
} catch (ServerException $e) {
    // 500, 503 - Server errors
    echo $e->getMessage();
} catch (NusiiException $e) {
    // Catch-all for any other API errors
    echo $e->getMessage();
}

All exceptions extend NusiiException, so you can catch that to handle any API error.

Rate Limiting

The Nusii API allows 100 requests per 30 seconds. Rate limit information is tracked on the client instance:

$nusii->clients()->list();

echo $nusii->rateLimitRemaining;   // 99
echo $nusii->rateLimitRetryAfter;  // null (or seconds to wait)

Testing

Run the unit tests:

composer test

Or with Pest directly:

./vendor/bin/pest

Integration Tests

Integration tests run against a live API server. Set the environment variables and run:

NUSII_API_KEY=your-key NUSII_API_URL=http://localhost:3000 ./vendor/bin/pest tests/IntegrationTest.php

Integration tests are automatically skipped when NUSII_API_KEY is not set.

Authentication

The library uses token authentication. Include your API key when creating the client:

$nusii = new Nusii('your-api-key');

All requests include the header:

Authorization: Token token=your-api-key

You can find your API key in your Nusii account settings under Integrations.

Requirements
