An agile and robust headless eCommerce API, Tamio Transactions possess the power and flexibility to cater to diverse business requirements. Its capabilities extend to order creation in any currency and seamless integration of payments for your services or products within your operational flows. This serves to fortify your business with a versatile solution for managing transactions, bolstering revenue collection, and improving customer experience.

The transaction process with Tamio, while encompassing a few key concepts, is designed for simplicity and efficiency. It empowers you to swiftly navigate through the stages of transaction creation, invoice generation, and payment capture, saving you both time and effort. The process ensures every transaction is executed smoothly, reinforcing customer satisfaction and trust.

The key stages involved in a transaction flow encompass:

Upon successful payment receipt, the transaction lifecycle culminates, resulting in the generation of an Invoice. Additionally, if the order contains billing plans or if an instalment plan facilitated the transaction payment, a Subscription is also produced.

Upon finalising a transaction, the next step is payment capture. This procedure varies based on the chosen payment method. Some methods undergo automatic processing, whereas others may necessitate additional actions from the customer. Such actions may involve credit card number input or redirection to an external webpage.

The fastest and easiest way to handle payment capture is to use our Javascript SDK. It supports all payment methods, including any 3d secure or two-factor payment authorisation that might be required. It renders the necessary payment forms and call-to-action buttons the customer might need to interact with to make a payment.

Once you have created a transaction, follow the steps below to finalise it and set up payment capturing.

Step 1: Load the SKD on your page

Step 2: Initialise the SDK with your publishable developer token. You can create a token in the developers' section in your Tamio dashboard.

Step 3: Finalise the transaction and render the payment forms to the customer. Pass the transaction ID, the payment method and the container element that you want the elements to render in.

In some cases, you might want to check if a coupon is valid before creating a transaction. For this use-case, you can use the validateCoupons method.

Once payment has been confirmed and an invoice has been registered, several actions can occur.

Employ the Estimate Transaction endpoint if you wish to pre-calculate an order's cost before initiating a transaction, or to assess potential payment options available to a prospective customer.

Tamio caters to non-developers and those preferring not to engage with code, offering the option to generate checkout pages instantaneously with our visual builder through Tamio sites. Our invoice generator offers the additional convenience of creating unlimited invoices, each with its unique hosted page to facilitate payment capture.
