# Ramp Install Auth

## Overview

Set up Ramp API authentication using OAuth2 client credentials flow with sandbox and production environments.

## Prerequisites

- Ramp account with API access
- Client ID and Client Secret from Ramp Dashboard

## Instructions

### Step 1: Get API Credentials

```text
1. Go to Ramp Dashboard > Settings > Developer
2. Create new API application
3. Copy Client ID and Client Secret
4. Note: Sandbox URL is sandbox-api.ramp.com, Production is api.ramp.com
```

### Step 2: Configure Environment

```bash
# .env
RAMP_CLIENT_ID=your_client_id
RAMP_CLIENT_SECRET=your_client_secret
RAMP_BASE_URL=https://sandbox-api.ramp.com/v1  # Switch to api.ramp.com for prod
```

### Step 3: Obtain Access Token

```python
import os, requests

token_resp = requests.post("https://sandbox-api.ramp.com/v1/token", data={
    "grant_type": "client_credentials",
    "client_id": os.environ["RAMP_CLIENT_ID"],
    "client_secret": os.environ["RAMP_CLIENT_SECRET"],
})
token_resp.raise_for_status()
access_token = token_resp.json()["access_token"]
print(f"Token obtained (expires in {token_resp.json()['expires_in']}s)")
```

### Step 4: Verify Connection

```python
headers = {"Authorization": f"Bearer {access_token}"}
resp = requests.get(f"{os.environ['RAMP_BASE_URL']}/cards", headers=headers)
resp.raise_for_status()
cards = resp.json()["data"]
print(f"Connected! Found {len(cards)} cards")
```

## Output

- OAuth2 access token obtained
- API connectivity verified with card listing

## Error Handling

| Error | Cause | Solution |
|-------|-------|----------|
| `invalid_client` | Wrong credentials | Verify client_id/secret in Dashboard |
| `401 Unauthorized` | Token expired | Re-authenticate (tokens expire in 1 hour) |
| Wrong environment | Sandbox vs prod URL | Check RAMP_BASE_URL |
