# Consent Flow & Management

## Consent Flow[​](#consent-flow "Direct link to Consent Flow")

With bLink, your customers can easily and securely consent to the exchange of their data within seconds and without any paperwork.

bLink runs a fully digitalized consent flow, ensuring a smooth and secure onboarding experience for your customers. Powered by SIX's OAuth-based consent module, it facilitates two essential flows:

* the initial setup of connectivity between Service Provider and Service User, by which end customers connect their bank accounts with a Service User’s application, and
* the Service User automatically accessing and fetching customer data in operational workflows once consent is established, enabling the end customer to fully benefit from the integration.

With a fully standardized process, information can thereby be efficiently and seamlessly shared across system and application boundaries. Find out more about the relevance of the consent flow in the chapter [Operational Best Practice](/docs/best-practice.md#seamless-cross-application-flows).

## Consent Management[​](#consent-management "Direct link to Consent Management")

bLink offers two ways to integrate the consent module: *Consent Management 2.0* or using *Consent Management 2.0 with Consent-as-a-Service (CaaS)*, a standardized token store service that is provided by SIX.

Find out more about the two methods in our [Architecture Guidelines](/docs/architecture/architecture-su.md#consent-management-permissions-and-tokens) and in the [Technical Documentation](/api-reference/authentication/consent-management/.md).
