​

Variable Object (for variableList when cacheKeyType=CUSTOM)

{
  "name": "userId",
  "type": "HEADER",
  "dataType": "STRING"
}

​

EnumVariableType

• HEADER - Extract from HTTP header
• PARAMETER - Extract from query parameter

Response

​

Success Response (200 OK)

  "success": true
}

When deploy=true is specified:

    "success": true,
    "deploymentResults": [
      {
        "environmentName": "production",
        "success": true,
        "message": "Deployment successful"
      }
    ]
  }
}

​

Response Fields

Example 3: Save and Deploy

curl -X PATCH \
  "https://demo.apinizer.com/apiops/projects/MyProject/apiProxies/MyAPI/settings/cache/" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "cacheSettings": {
      "name": "Cache Settings",
      "cacheActive": true,
      "cacheOnlyHttpGetRequests": true,
      "cacheKeyType": "QUERY_PARAMS",
      "cacheStorageType": "DISTRIBUTED",
      "capacity": 2000,
      "ttl": 1800,
      "handlingAction": "STOP",
      "cacheNullValue": false
    },
    "deploy": true,
    "deployTargetEnvironmentNameList": ["production"]
  }'

Notes and Warnings

• handlingAction: Required field. CONTINUE allows backend call for logging, STOP prevents backend call
• Cache Key: When cacheKeyType=CUSTOM, provide variableList to define cache key components
• Storage Type: LOCAL cache is faster but not shared; DISTRIBUTED cache is shared across workers
• TTL: Cache entries expire after TTL seconds
• Capacity: Maximum number of cache entries (older entries are evicted when limit reached)
• GET Only: When cacheOnlyHttpGetRequests=true, only GET requests are cached (endpoint-level cache can override)
• Null Values: When cacheNullValue=false, null/empty responses are not cached
• Deploy: When deploy=true, the API proxy is automatically deployed to the specified environments after saving

​

Permissions

User must have API_MANAGEMENT + MANAGE permission in the project.
