# Decide Gateway: Priority List Based

`PL_BASED_ROUTING` evaluates active priority logic and returns the selected connector order.

```bash theme={null}
curl --location "$BASE_URL/decide-gateway" \
  --header "$AUTH_HEADER" \
  --header "Content-Type: application/json" \
  --data '{
    "merchantId": "merchant_demo",
    "eligibleGatewayList": ["stripe", "adyen", "checkout"],
    "rankingAlgorithm": "PL_BASED_ROUTING",
    "eliminationEnabled": false,
    "enableMultiObjective": false,
    "paymentInfo": {
      "paymentId": "pl_001",
      "amount": 1000,
      "currency": "USD",
      "country": "US",
      "paymentType": "ORDER_PAYMENT",
      "paymentMethodType": "CARD",
      "paymentMethod": "CREDIT",
      "authType": "THREE_DS"
    }
  }'
```

```json theme={null}
{
  "decided_gateway": "stripe",
  "routing_approach": "PRIORITY_LOGIC",
  "priority_logic_output": {
    "isEnforcement": false,
    "gws": ["stripe", "adyen", "checkout"],
    "gatewayReferenceIds": {}
  },
  "reset_approach": "NO_RESET",
  "multi_objective_info": null
}
```

## Multi-Objective Option

When multi-objective routing is enabled (request field `enableMultiObjective`, or the `multi_objective_routing_enabled` merchant feature flag), a cost-aware post-step may re-rank the SR result and the response gains a `multi_objective_info` block. Details and examples: [Multi-objective routing](/decision-engine-api-reference/api-reference/guides/run-transactions/decide-gateway-multi-objective).
