However, in some instances, XML is more appropriate as default message format. In this microlearning, we focus on changing the default message format and show the impact this has on flows in Create.

17 +In our crash course on the API Gateway pattern, we have learned about setting up the API Gateway. By default, the messaging format selected for your gateway is JSON. However, the default messaging format can be changed in your project to for example, XML. This change can be made in Design -> Settings -> API Management.

27 +After the flows are resetted in Create, the automatic flow creation in the Create phase is adapted to the new default setting. When changing the messaging format to XML, the components of newly generated flows are created with different names and settings. The image below shows an example of an API GET operation with XML as the default messaging format. Besides the changed naming of the transformation, no JSON factory support objects are required in your flow in comparison with a JSON messaging format.

28 -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 special 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:

33 -In both cases, eMagiz will automatically update your Swagger definition and all-entry flow by recreating the swagger definition to reflect these changes and executing a version bump of the all-entry.
33 +* The default messaging format can be changed to XML
34 +* Updating this only affects new flows
35 +* Migrating existing operations can be done by resetting the exit flow

44 -* Updating can happen from Design
45 -* Updating can happen from Create
46 -* Both situations have a different impact
47 -* Adding a new operation to an existing solution does not involve a reset
48 -* Updating from Create does not involve a reset
