Installation

Add this to your package's pubspec.yaml file:

dependencies:
  fatoorah_pay: ^1.0.0

Then run:

flutter pub get

Simply create a link, share it with your customer, and they can pay directly.

Payment links are pre-configured payment pages that you can share with customers via:

  • Email
  • SMS
  • Social media
  • Your website
  • QR codes

Customers click the link, enter their payment details, and complete the payment - no coding required on your end.

Payment links are ideal for:

✅ Invoices - Send payment links with invoices ✅ One-time payments - Simple, quick payments ✅ Email/SMS campaigns - Share links in messages ✅ Manual order processing - Create links on-demand ✅ Non-integrated scenarios - When you can't integrate directly

Not ideal for:

❌ Real-time checkout flows (use Payment Intentions instead) ❌ Recurring subscriptions (use subscription endpoints) ❌ Complex multi-step processes

Creates a new payment link that can be shared with customers. Payment links allow customers to complete payments without requiring integration on your side.

Key Features:

  • Shareable URL for customers
  • Automatic expiration (default 24 hours)
  • Webhook notifications on payment status changes
  • Support for external references (invoice IDs, order IDs, etc.)

For complete code examples, see Payment Link Examples

Retrieve a paginated list of all payment links for your account.

Supports filtering and sorting by various fields.

Note:

  • Pagination starts from page 0 (not 1)
  • page, size, sortBy, and sortDirection parameters are optional - if not provided, they won't be sent in the request

For complete code examples, see Payment Link Examples

Retrieve details of a specific payment link by its ID.

Payment Intentions

Payment intentions represent the lifecycle of a payment from creation to completion. Use payment intentions when you want to integrate payments directly into your application flow with full programmatic control.

What are Payment Intentions?

Payment intentions are payment objects that you create programmatically and manage through their lifecycle. Unlike payment links (which are shareable URLs), payment intentions give you:

  • Full control over the payment flow
  • Detailed line items and billing information
  • Programmatic status management
  • Integration with your checkout process

When to Use Payment Intentions

Payment intentions are ideal for:

✅ E-commerce checkouts - Integrated checkout flows ✅ In-app payments - Mobile and web applications ✅ Custom checkout pages - Your own payment UI ✅ Multi-step processes - Complex payment flows ✅ Real-time status updates - Immediate payment confirmation

Not ideal for:

❌ Simple email/SMS payments (use Payment Links instead) ❌ Manual order processing (use Payment Links instead)

Key Features

  • Programmatic payment processing
  • Support for multiple line items
  • Detailed billing information
  • Webhook notifications
  • Automatic expiration (default 24 hours)

Documentation

Error Handling

The SDK uses an ApiResult<T> pattern for all operations:

result.when(
  onSuccess: (data) {
    // Handle success
  },
  onFailure: (error) {
    if (error is AuthenticationException) {
      // Invalid API key
    } else if (error is ValidationException) {
      // Validation failed
    } else if (error is NetworkException) {
      // Network issue
    } else if (error is ServerException) {
      // Server error (500, etc.)
    }
  },
);
