Quick Start

SDK Setup & Configuration

You must configure the SDK once at the start of your application.

use ComplyanceSDK\GETSUnifySDK;
use ComplyanceSDK\Models\SDKConfig;
use ComplyanceSDK\Models\Source;
use ComplyanceSDK\Enums\SourceType;
use ComplyanceSDK\Enums\Environment;

// 1. Define your source info (Your App Name and Version)
$sources = [new Source('App name', 'Version', SourceType::fromString(SourceType::FIRST_PARTY))];

// 2. Set up configuration
// Change Environment::SANDBOX to Environment::PRODUCTION when going live
$config = new SDKConfig(
    'YOUR_API_KEY_HERE', 
    Environment::from(Environment::SANDBOX), 
    $sources
);

// 3. Initialize the SDK
GETSUnifySDK::configure($config);

The "Purpose" Workflow

The integration requires a specific two-stage process to ensure your document data correctly translates to regulatory standards.

Step 1: MAPPING (Setup & Template Creation)

Set the Purpose to "MAPPING" to push your raw data to the Complyance platform. This stage is used for initial field discovery and visualization.

  • In Code: Submit your payload with Purpose::from('MAPPING').
  • In Portal: Locate the uploaded payload, complete the field mapping, and save it as a successful Template.
  • Final Step: Register and bind your unique sourceName and sourceVersion to this template on the portal.

Step 2: INVOICING (Production Submission)

After your template is successfully bound to your source identifiers, change the Purpose to "INVOICING".

  • Action: The system now recognizes your sourceName/sourceVersion and applies the saved template logic to transform, validate, and officially submit the document to the tax authority.
  • Requirement: You must use the exact same Source identifiers registered during the Mapping phase.

How to change the Purpose in code:

use ComplyanceSDK\Enums\Purpose;

// 1. Initial Phase: Field Analysis & Template Binding
$currentPurpose = Purpose::from('MAPPING'); 

// 2. Final Phase: Official Submission using the bound template
// $currentPurpose = Purpose::from('INVOICING');

Why this structure is important:

  1. MAPPING is the "Discovery" phase where you build the blueprint.
  2. The Portal is where you finalize the logic and connect it to your sourceName.
  3. INVOICING is the "Execution" phase where the SDK performs the actual heavy lifting using that blueprint.

Running the PHP Script

After completing the SDK configuration and invoice submission steps, execute the PHP file from your terminal.

Step 1: Open Terminal

Navigate to your project directory:

cd /path/to/your/project

Step 2: Run the Script

Use the following command format to execute your PHP file:

php your_file_name.php

Replace your_file_name with the name of your PHP script.

Step 3: Verify Execution

  • After running the command, the terminal will display:

  • SDK configuration status

  • Mapping response

  • Invoice submission response

  • Or validation/error messages (if any)
