Thanks to the group for this thread. I’m likely going to have to go down a 
similar path soon and will be using this as a reference.

My biggest fear is that we haven’t had a real userID to phone to voicemail 
mapping over the years. It’s gonna be interesting going forward.

Subject: Re: [cisco-voip] Changing CUC UM Account with API?

I just wanted to send a quick update and another THANK YOU, this worked 
perfectly for adding office 365 accounts! Thanks so much. I only ran into one 
real issue, which I'll know more about next time... apparently, one of my POST 
requests actually worked and then added the UM account to the CUC user. I 
didn't know this happened because I guess I wasn't paying close enough 
attention. From that point on, I kept getting a "400 Bad Request."  We spun our 
wheels for an hour or so trying to figure out what was wrong with the web 
request. Turns out, there was nothing wrong and CUC responds with a 400 when 
you try to add a SECOND UM account. Derp. We deleted the one that was added 
during testing and were able to successfully put it back on.

FWIW, we used iwr from powershell, and not postman. Going through this exercise 
has really been eye opening on how this works. I just didn't "get it" before... 
one step closer to world domination :)

Thanks,
Nick

Taken a quick look and yeah, Anthony is correct in regards to the use of DELETE.

To Delete the existing UM Service account:
- A GET to 
https://<connection-server>/vmrest/users/<https://%3cconnection-server%3e/vmrest/users/>
 will dump the users on the Connection Server.
- For each user you'll find an objectId listed. A GET to 
https://<connection-server>/vmrest/users/<user-objectid>/externalserviceaccounts<https://%3cconnection-server%3e/vmrest/users/%3cuser-objectid%3e/externalserviceaccounts>
 will dump any attached external services account for the user.
- You'll want to then grab the '<URI>' value in the returned data (looking like 
'/vmrest/users/<user-objectid>/externalserviceaccounts/<ObjectId>' and execute 
a DELETE against that URI (obv adding 'https://<connection-server>/' to the 
URI).
- Note that you need to use basic auth to login as an appadmin for the request.
- CURL wise: curl --basic --user <app admin>:<password> -k -X DELETE 
https://<connection-server>/vmrest/users/<user-objectid>/externalserviceaccounts/<object-id<https://%3cconnection-server%3e/vmrest/users/%3cuser-objectid%3e/externalserviceaccounts/%3cobject-id>>

To add the new UM Service to the user account:
- Update the XML below with:
   - %umservice-objectid% - The guid of the um service (easiest way is to grab 
the guid from the CUC Admin pages for the UM service listed under Unified 
Messaging > Unified Messaging Services).
   - %user-objectid% - As per the id you found prev when you did the delete.

<ExternalServiceAccount>

     <ExternalServiceObjectId>%umservice-objectid%</ExternalServiceObjectId>

     <SubscriberObjectId>%user-objectid%</SubscriberObjectId>

     <UserURI>/vmrest/users/%user-objectid%</UserURI>

     <EnableCalendarCapability>true</EnableCalendarCapability>

     <EnableMeetingCapability>false</EnableMeetingCapability>

     <EnableTtsOfEmailCapability>true</EnableTtsOfEmailCapability>

     <IsPrimaryMeetingService>false</IsPrimaryMeetingService>

     <LoginType>0</LoginType>

     <UserPassword/>

     <EnableMailboxSynchCapability>true</EnableMailboxSynchCapability>

     <EmailAddressUseCorp>true</EmailAddressUseCorp>

</ExternalServiceAccount>
You'll need to then POST this XML to url: 
'https://<connection-server>/vmrest/users/<user-objectid>/externalserviceaccounts'.
  Note that again you need to provide basic auth.

Note that the XML Above worked for me when adding a UM Service configured to 
point to Exchange, so ~in theory~ this should work for O365 as well.  Not got a 
tenancy I can test against at the moment in O365 to confirm.

If you use Postman to run this stuff, make sure you use the desktop version 
(not the chrome extension version), and make sure you add the 'Origin' header.  
The value should be the url of the CUC Server (eg 'http://172.20.2.25').  This 
should stop you receiving the 'domain not allowed' error message'

Hope this assists.

While people are possibly playing around with the CUC Provisioning API, let me 
know if you ever get the import of CUCM Local users to CUC working correctly.  
The last rollout I did I was trying to pull in local users but the api just 
didn't work.  Had to use LDAP imports instead.  Never looked too much deeper as 
I just needed to get on with things.

But yeah, the API for CUC is really hit and miss.  lol, and the API for UCCX 
can be a bit the same.

Wow, the documentation for the CUC API has gone to shit.  There's literally a 
link on the developer.cisco.com<http://developer.cisco.com> site that sends you 
to a wiki site, which itself then sends you to 
developer.cisco.com<http://developer.cisco.com>.  Nice.

Anyway, I tried to look into this quick for you, but I got stuck with the 
documentation on POSTing a new UM account for end users.  It literally just 
says:

"To create an a new external service account, POST an XML document (formatted 
similar to the one above) to the following URL:
POST 
https://<connection-server>/vmrest/users/<user-objectid>/externalserviceaccounts<https://%3cconnection-server%3e/vmrest/users/%3cuser-objectid%3e/externalserviceaccounts>"
Source: 
http://docwiki.cisco.com/wiki/Cisco_Unity_Connection_Provisioning_Interface_(CUPI)_API_--_User_Unified_Messaging_Account

The key part being "similar to."  It's beyond my comprehension that anyone 
would think that this is sufficient documentation to make an API request work.  
Suffice it to say, it didn't work for me, and now I'm done troubleshooting it.

Since any good REST API should use CRUD, it would then make sense that you 
issue an HTTP DELETE to the user object + um account object URI to remove the 
old one, after you successfully run the POST above to Create the new 
association.

Good luck.  If I have more time in the next few days, I'll try again.

I can handle most things in CUCM with SOAP, but I always get confused when 
trying to use VMREST in CUC. I cannot find a way to add and remove a UM account 
via automation. We're stuck using a CSV and it's really putting a cramp in our 
migration to Exchange Online.

The particular change I'm needing is here: Users->EditMenu->Unified messaging 
accounts
1) Need to add an additional one that connects to Exchange Online (this already 
exists in CUC)
2) Need to delete the old one that connects to on prem Exchange. (Not delete 
the whole UM connector service, but just the account association to a 
particular user)

Does anyone have any pointers on this? We have batches of people migrating 
every week, sometimes multiple times per week... so I can't just make some 
global change.

We're on CUC 10.5

Thanks!
Nick

P.S.  I hate that MSFT and CSCO both have a product called "Unified Messaging" 
:)
