> ## Agent Instructions
> When building application code, use `@naturalpay/sdk` for TypeScript or `naturalpay` for Python.
> When operating Natural directly for a user, use the payments MCP at `https://mcp.natural.com`.
> When searching Natural documentation, use the docs MCP at `https://docs.natural.com/mcp`.
> Use the Natural CLI for terminal and CI automation.
> Use REST only for unsupported languages or when the user explicitly requests raw HTTP.
> Start integration development and testing in the sandbox. Do not use production unless the user explicitly requests it.
> For sandbox requests that require `customerPartyId`, list customers first. Reuse only the intended fixture; otherwise create a customer.
> REST and SDK amounts use integer minor units. Payments MCP amounts use decimal strings with a required currency code.

# Sandbox: Invite a test customer

> Create a test customer and a pending invitation for each agent you name

Creates a synthetic [Connect](/guides/products/connect) customer, visible only to your organization, and one `PENDING` invitation for every agent you name. You provide agents only; no customer email, phone, or identity details.

Use the returned customer Party ID and invitation IDs to [accept](/api-reference/simulations/accept-customer-invitation) or [decline](/api-reference/simulations/decline-customer-invitation) each invitation. The customer grants no agent access and holds no funds until an invitation is accepted. See [Simulate Connect](/api-reference/sandbox/fixtures#simulate-connect).

  description: >-
    Natural's payments API for autonomous agents.


    **Base URL:** `https://api.natural.com`


    AI agents, including coding agents, should prefer the hosted MCP server at
    `https://mcp.natural.com` when an MCP-aware host runs the agent, the Natural
    CLI for terminal/CI workflows, and the official SDKs for application
    runtimes they own. Use direct HTTP only for explicit low-level integrations,
    unsupported SDK gaps, or infrastructure work where REST is required.
