Payent Cielo

This module adds Cielo as a payment provider in the Payment Acquirer settings. Once configured, customers can pay by credit card using Cielo, and their card can be saved as a payment token for later use.

Where it appears: - In the payment acquirer configuration screen, extra fields appear when the provider is Cielo: Cielo Merchant Id, Cielo Merchant Key and Checkout Image URL. - On the website checkout, a card form collects card number, holder name, expiry, CVC and brand.

Business rules and automatic behaviour: - Merchant Id and Merchant Key are required when the provider is Cielo. - In test mode, fixed sandbox credentials are used; in production, the merchant credentials entered in the settings are used. - Card data is sent to Cielo to obtain a token; the token is stored, and sensitive card details are removed from the saved token. - A payment transaction is created and its status is updated automatically based on Cielo's response: authorized, done or cancelled. - Capture and void links returned by Cielo are saved on the transaction so staff can capture or cancel an authorized payment later. - The payment token is marked as verified after a successful authorization.

It touches the payment acquirer, payment token and payment transaction records, and adds a card entry form and an error popup on the website.
