Square offers digital payments and financial services to its customers. Developers can learn to integrate Square APIs to help businesses of almost all types and sizes grow.

This course provides a strong foundation with Square APIs for business operations. You'll get introduced to different payment, order, and invoice APIs. By the end of the course, you'll get hands-on experience with an e-commerce web application integrated with Square APIs. You’ll use these APIs to complete the purchase and payment workflow. Such a workflow usually requires creating an order, generating an invoice, and finally paying for it. Square takes care of all of it with just a few API calls.

Handling Financial Services with Square API in Python

The possible statuses of payments are `APPROVED`, `COMPLETED`, `CANCELED`, or `FAILED`. Let's try to understand the workflow of Square payments:

- `COMPLETED`: If the `autocomplete` field is set to `true` in the CreatePayment request, the payment is processed immediately, and the resulting Payment object has the `status` field set to `COMPLETED`. This is also the default behavior. It  means that if the `autocomplete` field is not set, the payment is set to complete immediately after they are created.

- `APPROVED`: If the `autocomplete` field is set to `false` in the CreatePayment request, the resulting Payment object has a status set to `APPROVED` which means that we've only requested the payment authorization. We then have the following two options:

   - `COMPLETED`: Complete the payment by calling CompletePayment which changes the `status` to `COMPLETED`.

   - `CANCELED`: Cancel the payment by calling CancelPayment which changes the `status` to `CANCELED`.

- `FAILED`: If Square is unable to get the requested funds, the status is set to `FAILED`.
