Flow versioning and aliasing in Connect Customer
To improve maintenance efficiency and reduce deployment risks, Connect Customer supports versioning and aliasing for flows. This lets you track changes over time, roll back to a known-good state, and control which content is live without editing the flows that reference it.
- Flow version
-
A version is an immutable, point-in-time snapshot of the flow. You can continue to edit the flow and create new versions as needed. Connect Customer assigns each version a sequential number automatically.
- Flow alias
-
An alias is a reference to a specific version of the flow. Aliases let you switch between flow versions without updating each Connect Customer resource. Resources such as queues, quick connects, and phone numbers can reference a flow alias instead of a specific version. When you publish a new version, you point the alias to it, and every Connect Customer resource that uses the alias picks up the new version automatically. Each alias is assigned a unique alias ID when it's created, and you can also assign it an alias name.
Following are the benefits of using flow versioning and aliasing:
-
Immutable versions. Each published version is a point-in-time snapshot of the flow's content that remains unchanged, which provides consistency and reliability for rollback and audit.
-
Safer deployments. Aliases let you point live traffic at a specific version and switch versions with a single update, without republishing or relinking every reference.
-
Easier change tracking. Sequential version numbers (starting from 1) and human-readable version descriptions make it straightforward to see what changed and when.
Topics
Reference a version or alias of a flow
You can reference a specific version or alias of a flow by using the qualified ARN or ID:
-
flow-arn-or-id:VersionNumberreferences a specific version. -
flow-arn-or-id:AliasIdreferences an alias.
Create a version of a flow
When you publish a flow, select the Create new version check box to create a new version of the flow.
If a flow is already published, the Versions tab is enabled. You can also choose Create version to create a new version of the flow.
Create an alias for a flow
To create an alias, you must first create a version for the flow. After the version is created, navigate to the Aliases tab and choose Create alias to create a new alias for the flow. When you create the alias, you must associate it with a version.
After you associate an alias with a version, the Versions tab shows the associated alias for each version.
The Aliases tab lists each alias and the version it points to.
View a specific version or alias of a flow
To view a specific flow alias or version, choose the version or alias link on the Versions or Aliases list page. The designer opens in read-only mode.
Use flow versions and aliases
When you reference a flow, you can optionally use either an alias or a version. If you don't select an alias or version, the latest published content of the flow will be referenced.
Audit history
On the designer page, you can view and switch between different versions and aliases of the flow by using the Audit history dropdown list.
You can also track all the changes made to the different aliases and versions of the flow on the flow historical changes page.
Metrics
To view the metrics associated with a flow version or flow alias, you can do either of the following:
-
Open the flow version or alias in read-only mode, and then choose Show Metrics.
-
Use the Audit history dropdown list to switch to the alias or version, and then choose Show Metrics.
Reference aliases or versions in other resources
You can optionally reference an alias or version when you configure any of the following pages that require you to reference a flow:
-
Queues
-
Quick connects
-
Phone numbers
-
Test chat
-
Test management
-
Task template
-
