Open a change record after a password rotation

Updated 12 Oct 2026 3 min read

After a successful password rotation, this flow logs in to the change management API, records the rotation as a change and writes the change number on the vault item. Auditors can then match every password change to a change record. It uses the token pattern described in Call an API that needs a token.

Applies to

Who can do this

Monopam v2026.10

Super administrators.

Before you begin

  • A vault item with the change API's client ID (Username) and secret (Password). Here it is named cmdb-api-client.
  • A custom field type that applies to Vault item: LastChangeTicket (title Last change ticket).
  • A rotation policy on the vault items whose rotations should be recorded.

The flow

Step

Type

Settings

Trigger

A password rotation finishes

Event credential.rotate.

Rotation succeeded?

If (context)

All of: rotation.status equals succeeded. false goes to the Rotation failed stop.

Get a token

Ask an API

POST https://itsm.example.com/oauth/token, Content type application/json, body below, Save the answer as auth.

Record the change

Ask an API

POST https://itsm.example.com/api/changes, header Authorization: Bearer {{auth.json.access_token}}, body below, Save the answer as change.

Write the change number

Write a custom field

Field LastChangeTicket, Set, value {{change.json.number}}.

Done

Stop

OK, Change {{change.json.number}} recorded for {{credential.title}}.

Rotation failed

Stop

Warning, The rotation of {{credential.title}} failed; no change was recorded.

No token

Stop

From Get a token → failed. Failure, The change API refused the client credentials ({{auth.status}}).

Change not recorded

Stop

From Record the change → failed. Failure, The change API answered {{change.status}}: {{change.error}}

Body of Get a token:

{"client_id":"{{Vault.cmdb-api-client.UserName}}","client_secret":"{{Vault.cmdb-api-client.Password}}"}

Body of Record the change. The rotation event publishes the vault item's title and account name and, when the item belongs to a resource, the resource's fields. It never publishes the password.

{"shortDescription":"Password rotated: {{credential.title}}",
 "configurationItem":"{{resource.title}}",
 "account":"{{credential.userName}}",
 "requestedBy":"Monopam"}

The change API answers {"number":"CHG0001001","state":"Implemented",…}, so the number is change.json.number. The screenshots come from a lab API at http://localhost:4096.

Build it

  1. Open Scripts → Flows, click New Flow and choose the event A password rotation finishes.
  2. Add the condition first (1), so only successful rotations are recorded. Then Get a token and Record the change: its header carries the token (2), its body describes the rotation (3) and its answer is saved as change (4).

    Figure 1. The rotation flow and the Record the change step.

  3. Add Write the change number and the stops, then click Save & publish. A rotation flow needs no trigger binding: every published rotation flow answers every rotation.

Check the result

Rotate a vault item that has a rotation policy and open Scripts → Flow Runs. The condition (1) took true, the token (2) and the change (3) were answered, and the number was written (4).

Figure 2. The run after a rotation of web-01-deploy.

The vault item's Custom Fields tab shows the change number (1). The next rotation overwrites it with the new one; the vault item's audit trail keeps every value the flow wrote.

Troubleshooting

What you see

Why

What to do

Runs end at Rotation failed.

The rotation itself failed; nothing is recorded for it.

Open the vault item's Audits for the rotation error. A Linux resource with a custom SSH port needs it set under Advanced → Custom SSH Port.

Change not recorded with HTTP 400.

The change API rejected the body.

Compare the body with the API's required fields; a field the rotation does not publish becomes empty.

Nothing runs after a rotation.

The flow is not published or is disabled.

Check Flows for Not published or Disabled.
