2 -In the crash course on the API Gateway we discussed the various options available to [[secure>>doc:Main.eMagiz Academy.Microlearnings.Crash Course.Crash Course API Gateway.crashcourse-api-gateway-security.WebHome||target="blank"]] your API Gateway properly. In this microlearning, we will expand our knowledge on that topic by looking at a special case of securing your API Gateway. That case is special as you use an external identity provider (IDP) to govern the roles and users that have rights on your API Gateway.
2 +Within the platform of eMagiz, sometimes you need to send a particular command from the eMagiz portal to retrieve information or execute a specific action. These commands can happen from the Deploy and the Manage phase. The two most noteworthy examples of the triggered command queue are the runtime dashboard functionalities and the message redelivery actions.

12 +This microlearning focuses on the command queue. The command queue communicates between the eMagiz portal and an eMagiz runtime.
13 13  
14 -By image transformation, we mean transforming the raw data that represents an image into another image format.
14 +* Commands towards a runtime, for example, to retrieve runtime information in the runtime dashboard, are sent via the command queue
15 +* You can monitor the command queue the same way as any other queue within your model
16 +* The command queue is prominently used when accessing the [[Runtime Dashboard>>doc:Main.eMagiz Academy.Microlearnings.Crash Course.Crash Course Platform.crashcourse-platform-deploy-runtime-dashboard||target="blank"]] and when using [[Message Redelivery>>doc:Main.eMagiz Academy.Microlearnings.Intermediate Level.Message Redelivery.WebHome||target="blank"]]

18 -* Ensure you wrap the output image in something if you want to do additional transformations on the data further downstream

20 +Within the platform of eMagiz, sometimes you need to send a particular command from the eMagiz portal to retrieve information or execute a specific action.

22 -In most cases, you will transform XML messages to other XML messages, or you will transform JSON or EDI messages in another of these formats. However, sometimes you want to perform an image transformation. With this image transformation, you can convert images in specific formats to another format (i.e., png). This can come in handy when you want to standardize the image format before using it further downstream in your business application(s).
22 +For example, when you navigate the Runtime Dashboard and click on a runtime, the eMagiz portal will send a command to the runtime via the command queue to retrieve the runtime state. So, for example, the same logic applies when you select a flow and stop it.
23 23  
24 -Before we dive into the specifics of how to configure this, let us first consider the following:
24 +For Message redelivery, the command queue retrieves all messages in the dead letter queue and resends messages via the command queue.

26 +{{info}}When all commands sent from the eMagiz portal are not working across models, something is probably broken in the backend of the eMagiz platform. In these cases, please contact us at [[support@emagiz.com>>mailto:support@emagiz.com]]{{/info}}

32 -When turning to the Create phase of eMagiz, we need to open the flow and enter "Start Editing" mode to add the necessary component. For example, in the left panel, you can search for "Image." This will yield the following result.
