Overview

This PHP SDK allows you to integrate ApnaPayment's settlement system into your application. You can use it to create settlement accounts, create settlements, check settlement statuses, and more.

Installation

To use the ApnaPayment Settlement SDK, first install it via Composer:

composer require apna-payment/settlement-sdk

Configuration

After installation, publish the configuration file:

php artisan vendor:publish --provider="ApnaPayment\Settlements\SettlementServiceProvider" --tag="config"

This will publish a settlement-sdk.php configuration file to the config folder of your Laravel project.

In your .env file, set your API token:

SETTLEMENT_BASE_URL=<base_url_depending_on_env>

SETTLEMENT_API_TOKEN=<your_api_token_here>

Usage

Create a VPA-based settlement account

try{
    $account = (new SettlementAccountBuilder())
    ->setAccountHolderName("My Name")
    ->setType(SettlementAccountBuilder::$TYPE_VPA)
    ->setVirtualAddress("testvpa@hdfcbank")
    ->setNickname("My Temp account test");
    $accountId = Settlement::createAccount($account);
}
catch (\ApnaPayment\Settlements\Exceptions\DuplicationAccountException $e){
    //Account already exists
}

Create a bank account-based settlement account

try{
    $account = (new SettlementAccountBuilder())
    ->setType(SettlementAccountBuilder::$TYPE_BANK_ACCOUNT)
    ->setAccountNumber("988231872481874")
    ->setAccountHolderName("My Name")
    ->setIfscCode("IFSCTEST001")
    ->setNickname("My Name");
    $accountId = Settlement::createAccount($account);
}
catch (\ApnaPayment\Settlements\Exceptions\DuplicationAccountException $e){
    //Account already exists
}

Delete a settlement account

$is_deleted=Settlement::removeAccount($accountId); //returns boolean
if($is_deleted){
    //Account deleted successfully
}
else{
//Something went wrong
}

Fetch all settlements

$accounts = Settlement::getAllSettlements();

Fetch settlements for specific accounts

$accounts = Settlement::getSettlementsByAccount($accountId);

Handle an invalid account ID

try {
    $settlements = Settlement::getSettlementsByAccount("InvalidId");
} 
catch (\ApnaPayment\Settlements\Exceptions\InvalidAccountException) {
    $message = "Invalid Account";
}

Create settlement

$settlementBuilder = (new SettlementBuilder())
->setAmount(200.25)
->setRemarks("Test Payment")
->setSettlementAccountId($accountId);
$settlement = Settlement::createNewSettlement($settlementBuilder);

Exception Handling

try {
    $settlement = (new Settlement(config('settlement-sdk.api_token')))
->createSettlement($settlementBuilder);
} 
catch (\ApnaPayment\Settlements\Exceptions\DuplicateTransactionException $e) {
    $message = "Duplicate";
} 
catch (\ApnaPayment\Settlements\Exceptions\InvalidAccountException $e) {
    $message = "Invalid account";
} catch (\ApnaPayment\Settlements\Exceptions\LimitExceededException $e) {
    $message = "Limit exceeded";
}

Fetch account balance

$balance = Settlement::getBalance();

Find a settlement by ID

try{
    $settlement = Settlement::find($settlementId); //settlement id is always returned from creating a settlement (static or from object)
    // Now the 'data' attribute has status in it
    $arrayData=$settlement->toArray();
}
catch (\ApnaPayment\Settlements\Exceptions\SettlementNotFound $e){
    //Invalid settlement id
}

Find a settlement by TxnId

try{
    $settlement = Settlement::findByTxnId($txnId);
    $arrayData=$settlement->toArray();
    $pending=$settlement->isPending(); //call any instance methods

}
catch (\ApnaPayment\Settlements\Exceptions\SettlementNotFound $e){
//Invalid txnId
}

Usage of Webhook Base URL:

Callbacks V1

Note:

All Endpoints when triggered will expect 200-299 http response code, even if in the case 500,400 is thrown, there will always be one time updates to balance server load.

After our backend receives a valid web hook url for updates relating to following events:

1. Settlement status: {'completed','failed'}
2. Account Approval Update : { 'approved','rejected' }

Our Backend triggers an HTTP/HTTPS POST request to following endpoints:

1. {base_url}/settlement/status :

    {
        'id':  '<settlement_id>',
        'status':'completed'
    }

2. {base_url}/settlement/status :

    {
        'id':  '<settlement_id>',
        ‘status’:’failed’
    }

3. {base_url}/settlement_account/approval :

    { 
        'id':  '<settlement_account_id>',
        'status':'rejected'
    }

4.{base_url}/settlement_account/approval :

    {
        'id':  '<settlement_account_id>',
        'status':'approved'
    }

Querying the status of a settlement

Suppose you have the settlementId returned from Settlement::createSettlemen($settlementBuilder)

$settlement = new Settlement();
// Load the settlement data

$settlement->getSettlementById($settlementId)

// Now the 'data' attribute has status in it

if($settlement->isPending()){
    // Pending
}
else if($settlement->isProcessing()){
    // Processing
}
else if($settlement->isCompleted()){
    // Completed
}
else if( $settlement->isFailed()){
    // Failed 
}
