33 -After you have already added an integration to Create you might want to change the error handling, the structure of the request and/or response message, the parameters, etc. In all these scenarios you need to change something in the Design phase of eMagiz. The actual changing of these parts of the API Gateway solutions is specified in earlier microlearnings. However, what to do after you have made those changes is not yet discussed. In this microlearning, we will discuss that process within eMagiz. Note that this process **only** applies when the operation already exists in Create. If it does not yet exist in Create eMagiz will simply add the configuration to the existing flow without changing the remainder of the all-entry.

34 34  
35 -As you might know from our offering on the messaging pattern and how to update in those scenarios you can imagine that (parts of) the API Gateway flows need to be updated to reflect your changes. Depending on the exact change the effect will be seen in the 'all entry' or in one of the exit gates that is specific to an operation. The division can be made as follows:
35 +From our offering on the messaging pattern and how to update it in those scenarios, you can imagine that (parts of) the API Gateway flows need to be updated to reflect your changes. Depending on the exact change, the effect will be seen in the corresponding entry gate or the corresponding exit gate specific to an operation. The division can be made as follows:
36 36  
37 -* When you change something to the configuration of the API Gateway itself (i.e security, error handling, parameters) the change will **only** impact the all-entry
38 -* When you change something to the configuration of the backend operation (i.e. endpoint, parameter, system request/response) the change will **only** impact the specific exit gate
39 -* When you change the gateway request/response message (with transformation) the change will impact **both** the all-entry and the specific exit gate
37 +* When you change something in the configuration of the API Gateway operation itself (e.g., path, error handling, parameters), the change will only impact the corresponding entry gate.
38 +* When you change something in the configuration of the backend operation (i.e., endpoint, parameter, system request/response), the change will only impact the specific exit gate.
39 +* When you change the gateway request/response message (with transformation), the change will impact **both** the entry gate and the specific exit gate.
40 +* When you change the API Gateway's security configuration, the infra flow and all entry gates will be updated (by clicking on Update security in the context menu).
40 40  
41 -In some cases, version bumps are needed to confirm the change in Create. For exit gates, this process is identical to when you do a version bump of any messaging flow after updating for example a CDM message or message mapping. However, when you update something on the all-entry level what is needed differs. In case of a security change you need to reset the all-entry flow. To reset a flow simply access the context menu on flow level in Create (via a right-mouse click) and press Reset flow. In case of all other changes, no reset is needed, just a version bump.
42 +eMagiz will automate all changes on the entry gate level except for changing the security configuration due to the impact of such a change. When the change is executed, eMagiz will automatically create a new version of the entry gate to reflect the change. To update changes in the exit gate, you need to execute a manual version bump. This division is made because the exit gate can contain much more customization, while the entry gate is, in most cases, completely generated by eMagiz.

45 -After you press this option eMagiz will present you with a confirmation pop-up to ensure that you are 100% sure that this is the correct flow that you want to reset. This because resetting a flow means returning to the original state.
46 +Apart from updating your API Gateway solution in Create, you can only update parts of the API Gateway solution in Create. Here, we mainly talk about changing the gateway messages. Any other changes on the 'exit gate' level have no particular impact compared to changing parts of other flows. We discern two parts of updating a (gateway) message that you can execute in the Create phase:
