# API Keys

> Issue and manage credentials for the Integration API.

API keys let you connect your own systems (such as an ERP) to Fatorly's
Integration API. You can scope each key to exactly the access it needs and revoke
it at any time. Open it from **Settings → Integrations → API Keys**.

## Create an API key

<Steps>
  <Step title="Name the key">
    Enter a descriptive **Name** (e.g. "My ERP integration").
  </Step>

  <Step title="Choose scopes">
    Select only the scopes the integration needs (see below).
  </Step>

  <Step title="Create">
    Select **Create API Key**. The secret is shown **once** — copy it immediately
    and store it securely. You won't be able to see it again.
  </Step>
</Steps>

## Scopes

| Scope                                | Grants                        |
| ------------------------------------ | ----------------------------- |
| `invoices:read` / `invoices:write`   | Read / create invoices.       |
| `customers:read` / `customers:write` | Read / manage customers.      |
| `vendors:read` / `vendors:write`     | Read / manage vendors.        |
| `items:read` / `items:write`         | Read / manage items.          |
| `participants:read`                  | Look up network participants. |
| `webhooks:manage`                    | Manage webhook subscriptions. |

## Manage existing keys

The table lists each key's **Name** (with its ID prefix), **Scopes**, **Status**,
**Created**, and **Last Used** dates. Select **Revoke** to disable a key
immediately.

<Warning>
  The full secret is only displayed at creation time. If a key is lost or
  compromised, **Revoke** it and create a new one.
</Warning>
