Deploy BIG-IP in AWS with HA across AZ’s - without using EIP’s

hello, michael, first thank you for your support, I have some questions:

1.- "should really be using the Cloud Failover Extension (CFE)" do you mean that I can no longer use the iapp ha? or will it stop working?

2.- regarding CFE, I am having a lot of trouble following the documentation https://clouddocs.f5.com/products/extensions/f5-cloud-failover/latest/userguide/quickstart.html I don't know if there is another article where Explain better, I am following the steps and when I run the api rest https: // {{host}} / mgmt / shared / cloud-failover / info I get another message from the one shown in the guide.

Now about the statements that are placed in the API, I don't know what should be put exactly in the json and where that should be put in the postman.

If it is possible you could indicate your email to make your queries is only the final part of a deployment that I am doing, only that I am missing, my email is jenciso@securesoftcorp.com, do you have any email?
