# Bling ERP Skill

Integration with Bling ERP via REST API v3 (OAuth2 Bearer).

## When to use

- List or create products, services, or kits in Bling
- Create or query sales orders
- Manage contacts (customers/suppliers)
- Issue or list fiscal invoices (NF-e)
- Check or update stock levels

## Setup

This skill uses a Python client (`scripts/bling_client.py`) that handles OAuth2 Bearer auth with **automatic refresh on 401**. You do OAuth **once** via the CLI, then the skill refreshes tokens transparently forever.

### One-time OAuth setup

1. Create an app at https://developer.bling.com.br → "Meus Apps"
2. Set the app's redirect URI to: `http://localhost:8787/callback`
3. Copy the Client ID and Client Secret into `.env`:
   ```bash
   BLING_CLIENT_ID=...
   BLING_CLIENT_SECRET=...
   ```
4. Run the login helper:
   ```bash
   make bling-auth
   ```
   This opens your browser, captures the authorization code via a local callback server, exchanges it for `access_token` + `refresh_token`, and persists both to `.env`.

After this step, `.env` contains:
```bash
BLING_CLIENT_ID=...
BLING_CLIENT_SECRET=...
BLING_ACCESS_TOKEN=...
BLING_REFRESH_TOKEN=...
```

### How the auto-refresh works

`scripts/bling_client.py` is the single entry point for all API calls. On any `HTTP 401`, it:
1. Exchanges `BLING_REFRESH_TOKEN` for a new `access_token` + `refresh_token` at `https://www.bling.com.br/Api/v3/oauth/token` (Basic auth with Client ID/Secret)
2. Persists both back to `.env` and `os.environ`
3. Retries the original request once

Bling rotates the refresh token on every refresh, so **always** use this client — never call the API with raw `curl` unless you're debugging, otherwise you risk the `.env` tokens going stale.

### Calling the client

```bash
python3 .claude/skills/int-bling/scripts/bling_client.py GET /produtos --params page=1 limit=50
python3 .claude/skills/int-bling/scripts/bling_client.py POST /contatos --body '{"nome":"Acme","tipo":"J","numeroDocumento":"12345678000100"}'
python3 .claude/skills/int-bling/scripts/bling_client.py PUT /produtos/123 --body '{"preco":99.90}'
```

The client prints the JSON response to stdout and logs errors to stderr.

## Auth Model

- **Type:** OAuth2 Bearer Token
- **Header:** `Authorization: Bearer <token>`
- **Token lifetime:** short-lived; must be refreshed using the OAuth2 refresh token flow
- **Scopes:** defined per app in the Bling developer portal

## Pagination

All list endpoints use:
- `pagina` — page number (1-indexed)
- `limite` — items per page (default 100, max 100)

Date filters use `YYYY-MM-DD` format.

## Rate Limits

Bling API v3 does not publish a hard rate limit publicly. Observed safe throughput is ~10 requests/second. Back off on HTTP 429 responses. For detailed limits, see https://developer.bling.com.br.

## Notes

- This skill is based on the MCP implementation at `workspace/projects/mcp-dev-brasil/packages/erp/bling/src/index.ts` (mcp-dev-brasil project)
- For advanced endpoints not listed here (product variations, fiscal settings, categories, etc.), consult the official docs at https://developer.bling.com.br
- The OAuth2 token management (refresh flow) is not automated by this skill — ensure `BLING_ACCESS_TOKEN` is fresh before making calls
