How to Access Cisco CallManager (CUCM) with AXL API Postman Tool

Abdul Jaseem VP
Cisco Employee

AXL API programming is gaining its importance day by day. The Administrative XML Web Service (AXL) is an XML/SOAP based API that enables remote management of Cisco Unified Communications Manager (CUCM) using any programming languages such as Python.

Sending AXL requests to Cisco CUCM with Postman is pretty straight forward process. Postman is a tool for prototyping APIs, Google Chrome app for interacting with HTTP APIs. It presents you with a friendly GUI for constructing requests and reading responses.

Tool mainly for developers or anyone who wants an easy way for testing any web APIs (including Cisco's AXL API).


Tools Required

  • Postman
  • Cisco Unified Communications Manager

Step 1: Create Standard AXL API User in CUCM

You can go for either End User or Application user. Since the purpose is for some API testing, I go with Application user.

Go to User Management > User Settings > Access Control Group

On the top right corner, Related Links > Assign Role to Access Control Group. Select Standard AXL API Users3 Standard AXL API Users.png

Go to User Management > Application User and add a new user. Make sure you assign the Access Control Group just created.4 AXL Application User.png

Now we are ready with API user and basic settings required from CUCM side.

Step 2: Setting up Postman

Download the Postman tool from above link. Provide below URL in the address bar.

https://[CUCM IP OR FQDN]:8443/axl/

On the Authorization tab, select Type as Basic Auth, enter the User name and Password that we created in Step 1.5 Postman Basic Authentication with CUCM.png


Step 3: Send a GET Request to CUCM AXl API

Go to ‘BODY’ tab, select ‘GET’ at the address bar and click send.6 CUCM Postman GET.png

Note: Here you are not sending any data. It is just blank body. Once you scroll down, you will be able to see below,7 Postman GET request to CUCM TEST.png


At this point, everything looks good. We can start sending HTTP POST requests in body.

Step 4: Send HTTP Post to Pull Phone Details

Here is the CUCM AXL API query to pull all the Phone details.

<soapenv:Envelope xmlns:soapenv="" xmlns:ns="">

Paste the request in body of Postman and select Post request.8 CUCM AXL Phone Details query.png

Once you send the request, here is what you get.

Do you know how to create requests using the plus sign? I can't get information of lines when using the E164 format.


Receiving HTTP-200 success response when invoking GET operation using But receiving HTTP-599 when doing POST with below SOAP body. Any suggestions?
