Summary

Confluence Data Center is unable to receive when calling REST API in the Postman client.

Environment

  • Confluence Data Center 7.13.7

Diagnosis

  • Check if you have enabled rate limit in Confluence.

  • Check if you can call REST API using the curl command 

    1 2 3 curl -u <username>:<password> -X POST -H 'Content-Type: application/json' -d '{"type":"page","title":"new page", "space":{"key":"<space_key>"},"body":{"storage":{"value":"<p>This is <br/> a new page</p>","representation": "storage"}}}' https://BASEURL/rest/api/content/ | python -mjson.tool
  • Check Confluence access log if you see the PostmanRuntime/7.29.0 request like this (if not move to the solution): 

    1 [29/Jun/2022:10:43:10 +0200] xxxx http-nio-27164-exec-5 0:0:0:0:0:0:0:1 POST /c7164/rest/api/content/ HTTP/1.1 200 140ms 1691 - PostmanRuntime/7.29.0

Cause

Postman Client is not accessible when calling to Confluence Proxy URL.

Solution

Bypass Load Balancer proxy and call the Rest API to the confluence node:

Add a new connector port 8092 to the <install-confluence-folder>/conf/server.xml on both nodes: 

1 2 <Connector port="8092" connectionTimeout="20000" maxThreads="200" minSpareThreads="10"      enableLookups="false" acceptCount="10" URIEncoding="UTF-8" />

The parameter above should be added under port 8090 connectors.

Restart both nodes and change the REST API URL to http://ip-address:8092/rest/api/content/ in Postman. Attempt to send the request to create a new page.

The IP address can be any node IP.
