# Providers

> What a customer can connect, and what each one can do.

A **provider** is one account a customer connects: a bank, a corporate card platform, a crypto account, a shopping wallet. Your app declares which providers it integrates when you register it, and the consent page offers at most those.

Several providers connected by one customer make up their [Wallet](/build/wallet).

## What can be connected

| Provider     | What it can do                                                                                                                                                                     |
| ------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Durango**  | ACH and wire payments, and transfers. The demo bank: nothing here is money.                                                                                                        |
| **Brex**     | ACH and wire payments to vendors from the corporate account, and transfers between its own accounts.                                                                               |
| **Narmi**    | ACH and wire payments from the bank account, and transfers between its own accounts.                                                                                               |
| **Banno**    | Same as Narmi.                                                                                                                                                                     |
| **Apiture**  | Same as Narmi.                                                                                                                                                                     |
| **Coinbase** | USDC and crypto payouts, buying crypto with the account's own USD or USDC, moves between the customer's own balances, and withdrawals to a bank they own. No vendor ACH, no wires. |
| **Link**     | One-time virtual cards for merchant purchases through the customer's Link wallet. Shopping only, no payments to payees.                                                            |

Capability is the provider's, not Payman's. Do not rule a request out in your prompt because it sounds like it belongs to a different kind of institution. Call the tool and let the answer say.

## How a customer connects one

| Provider                             | On the consent page                 |
| ------------------------------------ | ----------------------------------- |
| Durango, Brex, Narmi, Banno, Apiture | Paste a token from the institution. |
| Coinbase                             | Paste a CDP API key.                |
| Link                                 | A button. Nothing to paste.         |

Whatever it is, it goes in on Payman's own pages. Your app never sees it.

## Naming one in an instruction

Saying the provider routes the turn to it: "pay Acme **from Brex**", "send \$50 **with my Coinbase**", "buy it **with my Link wallet**". Payman matches whole words, so "LinkedIn" and a pasted URL never count as Link.

You can also name it outside the sentence, with the `provider` option on `run()`. See [the Wallet](/build/wallet).

## Sandbox and live

**Durango is the only sandbox provider.** A sandbox app offers Durango and nothing else. Every other provider is live.

<Warning>
  **Coinbase has no sandbox anywhere.** Coinbase does not offer a customer-facing test environment, so a Coinbase connection moves real money the first time it is used. There is no safe version of it to try.
</Warning>
