HTTP Callout in Flow without Code

Can this method be used in Flow to create records from an external system API (Microsoft Nav) ?

Can i access my external app data from flow builder?

1.If Contact record is Updated , i want to pass that record id to the API Call, How Can I do that?
2.Couldn't able to see the option "Permission Set Mappings" in the External Credentials. What should I do now?
