cURL Example

Example 1: Enable Custom JSON Response

curl -X PATCH \
  "https://demo.apinizer.com/apiops/projects/MyProject/apiProxies/MyAPI/settings/custom-message/" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "buildCustomMessage": true,
    "customMessageTemplate": "{\"status\": \"ok\", \"version\": \"1.0\"}",
    "customMessageContentType": "application/json",
    "customMessageHttpStatusCode": 200
  }'

Example 2: Enable Custom XML Response

curl -X PATCH \
  "https://demo.apinizer.com/apiops/projects/MyProject/apiProxies/MyAPI/settings/custom-message/" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "buildCustomMessage": true,
    "customMessageTemplate": "<response><status>ok</status><message>Service healthy</message></response>",
    "customMessageContentType": "application/xml",
    "customMessageHttpStatusCode": 200
  }'

Example 3: Disable Custom Message (Resume Normal Routing)

curl -X PATCH \
  "https://demo.apinizer.com/apiops/projects/MyProject/apiProxies/MyAPI/settings/custom-message/" \
  -H "Authorization: Bearer YOUR_TOKEN" \

  -d '{
    "buildCustomMessage": true,
    "customMessageTemplate": "{\"status\": \"ok\"}",
    "customMessageContentType": "application/json",
    "deploy": true,
    "deployTargetEnvironmentNameList": ["production"]
  }'

Notes and Warnings

Custom Message Mode: When buildCustomMessage=true, the gateway returns the custom response template instead of routing to backend
Template Variables: The template supports Apinizer variables (e.g., ${request_httpMethod}, ${request_uri}) that are resolved at runtime
Content Type: Set customMessageContentType to match your template format (e.g., application/json, application/xml, text/plain)
HTTP Status Code: The customMessageHttpStatusCode overrides the default 200 status code
Use Cases: Health check endpoints, mock responses, maintenance responses, API versioning redirects
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.
