How to get short ORG ID from long orgId?

[YukioHashimoto]

Hello. Experts,

Are there any ways to reverse lookup to get short ORG-ID displayed in Control Hub from  long ORG-ID starting with "Y2lzY29zcGFyazovL3..." used in Webex API?

We would like to do the reverse way of the following operation:

ORG-ID displayed  in Control Hub: 42840e74-06a1-8888-b8c6-98a416dXXXXX

curl -L --request GET \--url https://webexapis.com/v1/organizations/42840e74-06a1-8888-b8c6-98a416dXXXXX

{

"id": "Y2lzY29zcGFyazovL3VzL09SR0FOSVpBVElPTi80Mjg0MGU3NC0wNmExLTQxNDEtYjhjNi05OGE0MXXXXXXXXXX",

"displayName": "XXXXXX",

"created": "2025-06-23T14:21:14.601Z"

}

To reverse lookup the short ORG-ID from the long ORG-ID used in Webex API, follow these steps:

1. Decode the long ORG-ID:

   • Base64Url decode the long ORG-ID. The decoded string will be formatted as follows: ciscospark://us/ORGANIZATION/{IdentityOrgUUID}.

2. Extract the Common Identity Organization ID:

   • Remove the ciscospark://us/ORGANIZATION/ prefix from the decoded string to leave the Common Identity Org UUID. This UUID is the short ORG-ID displayed in Control Hub.

For example:

• Long ORG-ID: Y2lzY29zcGFyazovL3VzL09SR0FOSVpBVElPTi80Mjg0MGU3NC0wNmExLTQxNDEtYjhjNi05OGE0MXXXXXXXXXX
• Decoded string: ciscospark://us/ORGANIZATION/42840e74-06a1-8888-b8c6-98a416dXXXXX
• Short ORG-ID: 42840e74-06a1-8888-b8c6-98a416dXXXXX
