Using ansible to make API requests to Splunk

I used the following format to make a REST API call against Splunk using Ansible.

- name: REST API call to Encrypt passwords
  uri:
    url: https://localhost:8089/servicesNS/nobody/{{ item.app_directory }}/storage/passwords
    user: admin
    password: changeme
    method: POST
    body:
      app_username:
      app_password: "{{ item.app_password }}"
      app_realm: (optional)
    body_format: form-urlencoded

Note: form-urlencoded is only supported on later versions of ansible.
