# Overview

> Customers are parties who have authorized your agents to act for them

A customer is a [Party](/guides/concepts/parties) who has authorized your [Agents](/guides/concepts/agents) to act for them. The customer resource is that relationship seen from your side: who connected, which of your agents they authorized, and what each agent may do.

This relationship is [Natural Connect](/guides/products/connect). Start one by [inviting a customer](/guides/connect/invite-customer). A customer's `id` is their party ID (`pty_*`).

## Invitations

Every customer relationship starts as an invitation. It names one or more agents, the permissions you're asking for, and optionally a per-transaction limit; the customer sees exactly what you asked for, and nothing moves until they accept. Pending invitations can be revoked, and accepted ones appear in your customer list.

## Acting for a customer

Each agent-customer pair carries its own permissions and limits. Depending on the grant, an agent can send and request payments on the customer's behalf, and with `external_accounts.create` it can [link the customer's bank account](/guides/connect/link-customer-bank).

## Revoking the relationship

Either side can revoke at any time, you through the API or dashboard and the customer from theirs. New activity stops immediately.
