Quipu API PHP

PHP classes that connect to the Quipu API see documentation

Requirements

• PHP 5.3 or higher
• cURL
• Quipu Account

Getting Started

Create a connection

The Quipu_Api_Connection class is a singleton class and will keep the connection open for 2 hours. The connection instance must be passed to each class.

$api_connection = Quipu_Api_Connection::get_instance('YOUR_APP_KEY', 'YOUR_APP_SECRET');

Create a Numbering Series

Pass the connection class to the numeration class, then call "create_series". The series will either be created or loaded if it already exists.

$quipu_num = new Quipu_Api_Numeration($api_connection);
$quipu_num->create_series('YOUR_PREFIX');

Create a Contact

The following parameters can be passed to create a contact.

• The only required field is "name".
• If "tax_id" is passed the class will try to load the contact if they already exist in Quipu.
• "country_code" should use [ISO 3166-1 alpha-2] (https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2)

$contact = array(
	"name" => "CONTACT_NAME",
	"tax_id" => "CONTACT_VAT_ID",
	"phone" => "CONTACT_PHONE ",
	"email" => "CONTACT_EMAIL",
	"address" => "CONTACT_ADDRESS",
	"town" => "CONTACT_CITY",
	"zip_code" => "CONTACT_ZIP_CODE",
	"country_code" => "CONTACT_CODE",
	"bank_account_number" => "IBAN"
);

Pass the connection class to the contact class, then call "create_contact", with the array above. The contact will either be created or loaded if they already exist.

$quipu_contact = new Quipu_Api_Contact($api_connection);
$quipu_contact->create_contact($contact);

Create an Invoice

The following parameters can be passed to create an invoice.

• "issue_date" is required
• "items" are required. "items" is an array with at least one value, all its variables are required
  • "product" is the item name
  • "cost" is the value in Euros
  • "quantity" must be at least 1
  • "vat_per" is the VAT percentage (not value)
• The accepted values for "payment_method" are detailed in the Quipu API documentation

$order = array(
	"payment_method" => "PAYMENT_METHOD",
	"issue_date" => "YYYY-mm-dd",
	"items" => array(
		"product" => "PRODUCT_NAME",
		"cost" => "PRODUCT_PRICE",
		"quantity" => "PRODUCT_QUANTITY",
		"vat_per" => "VAT_PERCENTAGE"
	);
);

Pass the connection class to the invoice class:

$quipu_invoice = new Quipu_Api_Invoice($api_connection);

You can first set the Numbering Series if one exists:

$quipu_invoice->set_numeration($quipu_num);

A contact is required or the invoice cannot be created:

$quipu_invoice->set_contact($quipu_contact);

Once the contact is passed to the class you can create an invoice

$quipu_invoice->create_invoice($order);

To get the internal Quipu Invoice id. Store locall to use for refunds.

$quipu_invoice->get_id()

Create a Refund

The following parameters can be passed to create a refund.

• "refund_date" is required
• "invoice_id" is required. This is the Quipu invoice id returned after creating an invoice
• "items" are NOT required. If "items" are not passed then the assumption is the whole invoice is being refunded, otherwise the assumption is it is a partial refund:
  • "product" is the item name
  • "cost" is the value in Euros
  • "quantity" must be at least 1
  • "vat_per" is the VAT percentage (not value)

$order = array(
	"invoice_id" => "QUIPU_INVOICE_ID",
	"refund_date" => "YYYY-mm-dd",
	"items" => array(
		"product" => "PRODUCT_NAME",
		"cost" => "PRODUCT_PRICE",
		"quantity" => "PRODUCT_QUANTITY",
		"vat_per" => "VAT_PERCENTAGE"
	);
);

Pass the connection class to the invoice class:

$quipu_invoice = new Quipu_Api_Invoice($api_connection);

You can first set the Refund Numbering Series if one exists:

$quipu_invoice->set_numeration($refund_num_series);

Call the 'refund_invoice' function to refund an invoice

$quipu_invoice->refund_invoice($order);
