This page lists environment variables for customizing endpoints in n8n.

Variable	Type	Default	Description
`N8N_PAYLOAD_SIZE_MAX`	Number	`16`	The maximum payload size in MiB. The default is 16 MiB, but this can be increased by adjusting the variable to a higher value. The n8n instance needs to be restarted to apply the new setting. Note: Increasing the payload size requires more memory and CPU resources and may impact performance. Ensure your infrastructure can handle larger payloads.
`N8N_FORMDATA_FILE_SIZE_MAX`	Number	`200`	Max payload size for files in form-data webhook payloads in MiB.
`N8N_METRICS`	Boolean	`false`	Whether to enable the `/metrics` endpoint.
`N8N_METRICS_PREFIX`	String	`n8n_`	Optional prefix for n8n specific metrics names.
`N8N_METRICS_INCLUDE_DEFAULT_METRICS`	Boolean	`true`	Whether to expose default system and node.js metrics.
`N8N_METRICS_INCLUDE_CACHE_METRICS`	Boolean	false	Whether to include metrics (true) for cache hits and misses, or not include them (false).
`N8N_METRICS_INCLUDE_MESSAGE_EVENT_BUS_METRICS`	Boolean	`false`	Whether to include metrics (true) for events, or not include them (false).
`N8N_METRICS_INCLUDE_WORKFLOW_ID_LABEL`	Boolean	`false`	Whether to include a label for the workflow ID on workflow metrics.
`N8N_METRICS_INCLUDE_NODE_TYPE_LABEL`	Boolean	`false`	Whether to include a label for the node type on node metrics.
`N8N_METRICS_INCLUDE_CREDENTIAL_TYPE_LABEL`	Boolean	`false`	Whether to include a label for the credential type on credential metrics.
`N8N_METRICS_INCLUDE_API_ENDPOINTS`	Boolean	`false`	Whether to expose metrics for API endpoints.
`N8N_METRICS_INCLUDE_API_PATH_LABEL`	Boolean	`false`	Whether to include a label for the path of API invocations.
`N8N_METRICS_INCLUDE_API_METHOD_LABEL`	Boolean	`false`	Whether to include a label for the HTTP method (GET, POST, ...) of API invocations.
`N8N_METRICS_INCLUDE_API_STATUS_CODE_LABEL`	Boolean	`false`	Whether to include a label for the HTTP status code (200, 404, ...) of API invocations.
`N8N_METRICS_INCLUDE_QUEUE_METRICS`	Boolean	`false`	Whether to include metrics for jobs in scaling mode.
`N8N_METRICS_QUEUE_METRICS_INTERVAL`	Integer	`20`	How often (in seconds) to update queue metrics.
`N8N_METRICS_INCLUDE_SSRF_METRICS`	Boolean	`false`	Whether to include metrics for SSRF protection checks.
`N8N_METRICS_INCLUDE_DNS_CACHE_METRICS`	Boolean	`false`	Whether to include metrics for the DNS cache (currently only used by SSRF protection).
`N8N_ENDPOINT_REST`	String	`rest`	The path used for REST endpoint.
`N8N_ENDPOINT_WEBHOOK`	String	`webhook`	The path used for webhook endpoint.
`N8N_ENDPOINT_WEBHOOK_TEST`	String	`webhook-test`	The path used for test-webhook endpoint.
`N8N_ENDPOINT_WEBHOOK_WAIT`	String	`webhook-waiting`	The path used for waiting-webhook endpoint.
`N8N_ENDPOINT_HEALTH`	String	`healthz`	The path used for health check endpoint.
`N8N_WEBHOOK_URL`	String	-	Sets the base URL for both test and production webhooks when running n8n behind a reverse proxy. Use this instead of the `N8N_ENDPOINT_` variables above, which set only the endpoint path*, not a URL. See Configure webhook URLs with reverse proxy.
`WEBHOOK_URL`	String	-	Deprecated alias of `N8N_WEBHOOK_URL`. Still works, but n8n logs a deprecation warning on startup.
`N8N_DISABLE_PRODUCTION_MAIN_PROCESS`	Boolean	`false`	Disable production webhooks from main process. This helps ensure no HTTP traffic load to main process when using webhook-specific processes.
