Detaching policies from a flow

To detach a policy from a flow, click the three-dot menu next to the flow and select Delete policy step

Classic Proxy Editor

To attach a policy to a flow:

1. Select an API proxy and navigate to the Develop view.
2. In the API Proxy Editor, select the flow to which you want to attach a policy in the Navigator pane.
   For example, the PreFlow flow is selected for the default API proxy endpoint in the following figure:
   
3. In the Design view, click +Step associated with the request or response flow to attach a policy. For example:
   
   The Add Step dialog opens displaying a categorized list of policies.
   
4. Scroll and select the policy type that you want to attach to the selected flow.
5. Modify the following fields.

   • Display Name: Unique display name for the policy. The UI will generate a default name, but it is advisable to create a descriptive name for the policy. This will ensure that other developers in your organization have an easy time understanding what the policy is intended to do.

   • Name: Unique name for the policy. The policy name matches the display name with the following exceptions:

     • Spaces are replaced by dashes.

     • Consecutive dashes are replaced by a single dash.

     • Except for dashes, underscores, and spaces (which are replaced, as noted above), characters that are not alphanumeric, such as pound signs, percent signs, ampersands, and so on, are removed.

6. Click Add.

   The policy is attached to the selected flow.

After the policy is attached, you’ll see the policy displayed in the Designer view for the flow, in this example the PreFlow of the default proxy endpoint, and in the Policies list in the Navigation pane. The Code view, which displays the XML for the newly attached policy, displays below the Designer view. Apigee generates an instance of the policy that contains a set of reasonable default values.

Adding a policy without attaching it to a flow

To add a policy without attaching it to a flow, which is useful for Handling faults, click + in the Policies bar in the Navigator view to open the Add Policy dialog and add the policy (as described in steps 4 through 6 in the previous section).

A policy that is not attached to any flow is flagged with the detached icon in the Policies list, as shown adjacent to the API key message policy shown in the previous figure.

After you create the policy, you can attach it to a flow by dragging and dropping it from the Policies list to the desired flow in the Designer view.

Detaching policies from a flow

To detach a policy from a Flow, select the Flow. Mouse over the icon for the policy in the Designer view of the Flow. Click the X in the circle that appears in the icon.
