# Integrations

Sarah connects to external services so you can sell, ship, and automate—based on your plan.

## What you can connect

| Area | Examples |
|------|----------|
| Payments | MercadoPago (online store), MercadoPago POS (in-store) |
| Messaging | WhatsApp assistant (configuration in Sarah) |
| Shipping | Carriers such as Correo Argentino where available |
| Automation | Make and Zapier (when enabled) |
| External systems | ERP, marketplaces, WMS (API and integration webhook) |

## Integration API and webhook

From **Company > Integration API and webhook** you can connect Sarah to external systems (ERP, marketplaces, etc.):

### Configuration

1. Go to **Company** in the main menu.
2. Find the **Integration API and webhook** section.
3. Configure:
   - **Outbound webhook URL**: HTTPS address where Sarah will send events (e.g. stock updates).
   - **Deposit for integrations**: deposit used for inbound sales and stock queries. If you choose **All deposits**, queried stock sums all deposits.

4. Save changes.

### Authentication

- Use the company's **integration key** as `Authorization: Bearer <integration_key>`.
- Optionally, Sarah can sign payloads with the `x-signature` header.
- For idempotency, you can send `x-idempotency-key` and `x-sent-at`.

> Treat the integration key as a secret. Do not publish it in repos, screenshots, or forums.

### Available endpoints

The same screen shows your instance endpoints:

| Endpoint | Use |
|----------|-----|
| **GET stock** | Query product stock from external systems |
| **POST events (inbound)** | Receive sales or other events from external systems |

Sarah also **notifies the configured webhook** when product stock changes (e.g. when creating or editing products).

For advanced technical details (formats, events, signatures), contact **Sarah support**.

## Where to configure other integrations

1. Open **Settings > Integrations** (and related sections such as **Company** or **Cash Registers** when the app directs you there).  
2. Only use credentials from the official provider (MercadoPago, carriers, etc.).  
3. Never paste integration keys or tokens into public forums, screenshots, or client-side code repos.
