cURL Example

​

Example 1: Configure Connection Timeouts

curl -X PATCH \
  "https://demo.apinizer.com/apiops/projects/MyProject/apiProxies/MyAPI/settings/connection/" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "connectionSettingsEnabled": true,
    "connectTimeout": 30,
    "readTimeout": 60,
    "connectionRequestTimeout": 30
  }'

​

Example 2: Configure Custom Connection Pool

curl -X PATCH \
  "https://demo.apinizer.com/apiops/projects/MyProject/apiProxies/MyAPI/settings/connection/" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "connectionSettingsEnabled": true,
    "connectionPoolManagementType": "CUSTOM",
    "customConnectionPoolSize": 20,
    "connectTimeout": 60,
    "readTimeout": 120
  }'

​

Example 3: Configure Connection Pool Stale/Idle Handling

curl -X PATCH \
  "https://demo.apinizer.com/apiops/projects/MyProject/apiProxies/MyAPI/settings/connection/" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "connectionSettingsEnabled": true,
    "validateAfterInactivity": 2000,
    "idleConnectionTimeout": 30
  }'

​

Example 4: Configure Header and Response Settings

curl -X PATCH \
  "https://demo.apinizer.com/apiops/projects/MyProject/apiProxies/MyAPI/settings/connection/" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "hopByHopHeaders": ["X-Internal-Trace", "X-Debug-Info"],
    "sendUserAgentToBackend": true,
    "userAgentValue": "Apinizer-Gateway/1.0",
    "enableDownload": true
  }'

​

Notes and Warnings

• Timeouts: Connection and read timeouts are in seconds; validateAfterInactivity is in milliseconds
• Connection Pool: validateAfterInactivity and idleConnectionTimeout help prevent stale connection issues; tune per backend load balancer keep-alive timeout
• Connection Pool: CUSTOM requires customConnectionPoolSize to be set
• Redirects: When redirectsEnabled=true, HTTP redirects are followed (max maxRedirects)
• Streaming: When enableStreaming=true, response is streamed instead of buffered
• Content Compression: When disableContentCompression=true, content compression is disabled
• Hop-by-Hop Headers: Headers listed in hopByHopHeaders are removed before the request is forwarded to the backend
• User-Agent: When sendUserAgentToBackend=true, the specified userAgentValue is sent as the User-Agent header to the backend
• Download Mode: When enableDownload=true, the gateway handles large response bodies as file downloads

Permissions

User must have API_MANAGEMENT + MANAGE permission in the project.
