A data flow has the following states: Draft, Awaiting Approval, Approved, and Live. By default, a data flow starts in the Draft state. When sent for Neo admin approval, it moves to Awaiting Approval. After the Neo admin approves it, the state changes to Approved.

You can make an Approved version Live, but only one approved version of an API can be Live at a time.

Approval Process for a Dataflow Version

A dataflow in the Live version is automatically triggered when invoked without including a variant ID in the headers. A dataflow version must be Approved before you can make it Live. Any user with Neo Edit access can create a dataflow and send it for approval.

Sending for Approval

To send a dataflow version for approval, click Send for approval after composing and testing the dataflow.
The dataflow moves to the Waiting Approval state.

Approving a Dataflow Version

The Neo Admin can approve the dataflow version. To approve,

1. From the Dataflow page, open the dataflow sent for approval.

2. From the version listing page for the dataflow, click on the version in Awaiting approval state.
   The dataflow composing page opens.

3. Click Review and approve.
   The version comparison opens.

4. Review the changes in the version.
   Note: If multiple versions of the dataflow exist, you can select the versions to compare from the drop-down.

5. Click Approve.
   A confirmation message appears.

6. In the confirmation message, enter a reason for approval and click Yes.

Note: Once a data flow is Approved, you cannot modify it.

Making a Version Live

To make a dataflow version Live,

   The dataflow composing page opens.

3. Click Make Live.
   A confirmation message appears.

Note:

• It takes around 10 minutes for a version to become Live.
• only one approved version of a dataflow can be Live at any time.
• You can roll back one version and make another version Live.

Versioning of a Dataflow

Neo dataflows are version-controlled. By default, a dataflow, when created, is in version v1 and in the Draft state, allowing users with edit access to compose the dataflow.

When a Neo Admin approves a version under review, the system automatically creates a new version with the next consecutive number. This new version starts in the Draft state and is a copy of the recently approved version, allowing further modifications.

Compare Versions

You can compare code changes between different versions of a dataflow.

To compare versions,

1. In the dataflow composing page, click on version compare icon.
   The compare versions window open.
2. In the compare versions window, use the drop-down to select any two versions to compare.

Note: The icon is available only for dataflows in the Draft state.

Restore a Version

You can revert the current version of the dataflow to the most recently approved version.

To restore a version,

1. In the dataflow composing page, click on restore version icon.
   A Revert Rule modal appears.
2. Enter the dataflow name.
3. Click Yes.

The version is retored to the most recently approved version.

Version Listing Page

The version listing page lists the different versions of a dataflow.

To access the version listing page, on the Dataflows page, click on the intended dataflow.
