uri post to avoid duplicate

[Veera]

Hi ,

I have the below uri module to post the details inside the web api

- name: REST POST Example
  uri:
    url: "{{ webapp_url }}/api/orgs"
    method: POST
    return_content: yes
    body: "{ \"name\": \"{{ project_name }}\" }"
    body_format: json
    validate_certs: no
    user: "{{ user }}"
    password: "{{ password }}"
    force_basic_auth: yes

while passing the variables as 

ansible-playbook myplay.yml  -e "project_name=first_project"  

n- number of times it works and overwrites the same first_project name.

Is there an option available to stop overwriting if the same project_name is  available with uri module? 

Or we have to use the GET method  to collect and compare the existing project_name , before writing using POST? or will  a conditional check can help ?

- name: Check if project name exists
  uri:
    url: "{{ webapp_url }}/api/orgs"
    method: GET
    return_content: yes

    validate_certs: no
    user: "{{ user }}"
    password: "{{ password }}"
    force_basic_auth: yes

  register: existing_projects

- name: Check if project name exists in the response
  set_fact:
    project_already_exists: "{{ project_name in existing_projects.json | json_query('*.name') }}"

- name: REST POST Example if project name doesn't exist

  uri:
    url: "{{ webapp_url }}/api/orgs"
    method: POST
    return_content: yes
    body: "{ \"name\": \"{{ project_name }}\" }"
    body_format: json
    validate_certs: no
    user: "{{ user }}"
    password: "{{ password }}"
    force_basic_auth: yes

  when: not project_already_exists

Thanks .. I am able to achieve it with the above logic and with "assert"  module for exiting the playbook if failed .
