Through a centralized integration, institutions can connect their digital and in-person channels to the authorization and processing services available on the platform. Supported channels may include: * Websites and checkout pages. * Mobile applications. * POS terminals and PinPads. * Proprietary ecommerce platforms. * Acquiring and payment facilitation systems. ## Service models Alignet can participate under different models according to the scope defined for each institution. ### Alignet as a processor The institution maintains its role as an acquirer or payment facilitator, while Alignet provides the technology infrastructure required to process transactions. The service may include: * Transaction reception. * Technical and business validations. * Routing to the corresponding networks or institutions. * Transaction authorization and response. * Reversals, voids, and queries. * Operation monitoring and traceability. ### Acquiring processing When an institution needs to operate as an acquirer for a card brand, the corresponding project with that brand must be completed beforehand. This process may include certifications, identifier enablement, connection setup, and operational validations before production begins. ## Brands and networks Depending on the contracted model, country, service availability, and applicable enablements, Alignet may act as a processor for different payment brands and networks, including: * Visa. * Mastercard. * American Express. * Diners Club. * UnionPay. * Other networks enabled for the project. The availability of each brand must be confirmed during the evaluation and scope definition stage. ## API integration Communication with the platform takes place through API services, allowing the institution to manage the transaction lifecycle from its own systems. The general flow is as follows: The transaction originates from the institution's, merchant's, or payment facilitator's channel. The institution submits the request through the processing API. Alignet validates the information and determines the applicable processing route. The operation is sent to the corresponding network, brand, or institution. Alignet returns the transaction result to the source system. ## Available operations Depending on the contracted scope, the integration may include the following operations: Process a new payment transaction. Query the status and result of an operation. Reverse a previously processed transaction. Manage voids or refunds according to the enabled model. ## Next steps Before starting the integration, the institution should review the technical, operational, and brand requirements that apply to the project.
