# Routing Config Endpoints

## Routing Keys

The dashboard uses this route to discover valid rule builder keys.

```bash theme={null}
curl "$BASE_URL/config/routing-keys" \
  --header "$AUTH_HEADER"
```

## Configure SR Dimensions

```bash theme={null}
curl --location "$BASE_URL/config-sr-dimension" \
  --header "$AUTH_HEADER" \
  --header "Content-Type: application/json" \
  --data '{
    "merchant_id": "merchant_demo",
    "dimensions": ["payment_method_type", "payment_method", "currency"]
  }'
```

## Get SR Dimensions

Read back the SR scoring dimensions currently configured for a merchant.

```bash theme={null}
curl "$BASE_URL/config-sr-dimension/merchant_demo" \
  --header "$AUTH_HEADER"
```

```json theme={null}
{
  "merchant_id": "merchant_demo",
  "paymentInfo": {
    "udfs": [],
    "fields": ["payment_method_type", "payment_method", "currency"]
  }
}
```

Returns an empty default (`fields: null`) when nothing has been configured for the merchant yet.

## GSM Options

Gateway Status Mapper rule catalog — the error-code classification options used by the `gsm-scoring-filter` merchant feature (see [Merchant Features](/decision-engine-api-reference/api-reference/guides/autopilot/merchant-features)).

```bash theme={null}
curl "$BASE_URL/gsm/options" \
  --header "$AUTH_HEADER"
```

```json theme={null}
{
  "rules": [
    {
      "connector": "stripe",
      "flow": "authorize",
      "subFlow": "card",
      "errorCode": "card_declined",
      "errorMessage": "Your card was declined.",
      "errorCategory": "soft_decline",
      "unifiedCode": "UE_001",
      "unifiedMessage": "Card declined by issuer",
      "decision": "retry"
    }
  ]
}
```
