 ### Using custom-defined roles to grant access
 In advanced scenarios where you need to specify a custom-defined permission role, you can do so in the flow action by entering a custom value for the *Roles* property in the following format:
 ```
-roles:<role-id>
+role:<role-id>
 ```

 Many people feel there are significant gaps between SharePoint Designer (classic) workflows and Power Automate flows, but the list is not long. Of course, there are some workarounds you should consider in your planning as you move from classic workflows to Power Automate flows.
 
 - **30 day run limit for flows** – SharePoint Designer workflows can run endlessly, but flows have a 30 day lifespan. Getting beyond this limitation means your flow will need to call itself in a re-entrant way to restart the clock ticking.
-- **HTTP Connector** – Flow has an HTTP connector (as an action), but it is a Premium connector. If you use HTTP calls extensively, you may want to create a “service account” user with a Power Automate license and run these flows with that user account. This also will make it easier to manage the set of flows you consider "enterprise" flows.
-- **Custom permissions on list items** – While there is not a flow action to accomplish this, it is possible to do it with an HTTP call.
+- **HTTP Connector** – If you make calls to SharePoint's REST API, then you can use  the ['Send HTTP Request to SharePoint'](../guidance/working-with-get-items-and-get-files.md) action available in the SharePoint connector. Flow also has a generic HTTP connector (as an action), but it is a Premium connector. If you use HTTP calls extensively, you may want to create a “service account” user with a Power Automate license and run these flows with that user account. This also will make it easier to manage the set of flows you consider "enterprise" flows. 
 - **Reusable Flows** – Using some modular thinking, you can create a master flow which a flow per list or library can call to do the heavy lifting. (In some ways this is even preferable, as you can edit a flow which is used in many locations centrally.) Alternatively, you can use flow actions to discover all of the lists or libraries which match some criteria and run the flow on them all on a timer rather than based on events.
 - **Workflow history storage** – Flows maintain a history in the context of the flow itself in the Power Automate dashboard. If you need tracking in your sites, you can have the flow log information in a list you create.
 - **Impersonation** - In SharePoint 2010 workflows, you can add an impersonation step to act as a different user. This capability is not readily available in flows.
