I am trying to access my production F5 device via Postman. When sending a GET request "https://<URL>" getting 200 OK however when I'm trying to get pool details by sending GET request to "https://<URL>/mgmt/tm/ltm/pool" getting "401 F5 Authorization Required"
Need guidance to resolve the issue.
Thanks in advance.
My understanding is that you have to authenticate to the BIG-IP system as an admin (or other user authorized to make API calls) before you can issue configuration commands. (Similarly to the way you have to log into the BIG-IP system in order to configure it.) There is a lab on F5 CloudDocs that has some examples of using Postman with BIG-IP, including how to authenticate. Hopefully that will give you what you need to get going.
Thanks for your reply, it worked in my LAB environment.
Can you help me, how to create Virtual server, pool and node via POSTMAN
BIG-IP programmability is a big topic, for which F5 provides a lot of training, much of which is free. For example, the link I sent you is part of a larger training course on BIG-IP programmability. You can access the base training contents here: https://clouddocs.f5.com/training/community/programmability/html/
If you haven't already done so, I suggest exploring the training pieces first to obtain a better understanding of the system's API and associated workflows before embarking on an actual configuration.
