Retry Ansible URI PUT API Call with a POST API Call - api

Question

Hello I am trying to run a PUT API call via Ansible URI module for a particular API Endpoint in my application, using a dictionary that contains the json files and that is defined as:
example: { 'example1' : 'v1', 'example2': 'v2''}
- name: Update existing
block:
- name: update existing
uri:
url: "{{url}}/api/{{item.key}}/"
method: PUT
body: "{{ lookup('file', 'example/{{item.key}}/{{item.value}}.json') }}"
status_code: 200
body_format: json
headers:
Content-Type: "application/json"
Authorization: "Token {{ token.json.token }}"
with_dict: "{{ example }}"
register: result
For the PUT api call, this api endpoint will fail is the {{item.key}} does not exist, e.g. if
"{{url}}/api/{{item.key}}/" endpoint does not exist, hence it will give a 4xx error.
Given the task fails and I get a 4xx error when the api endpoint for the item does not exist, I want to run a POST command for that same json file.
How can I do this in ansible, to retry a task that failed but only specifically for that {{item.key}} and {{item.value}} in dictionary?
or
Is there a better way to do this to retry a failed PUT with a POST command
I want to use the ansible URI module
Thanks!

You can ignore the error case and then loop through result.results with filtering to keep only errors. You can have access to the original item with item.item:
- name: update existing with PUT
uri:
url: "{{url}}/api/{{item.key}}/"
method: PUT
body: "{{ lookup('file', 'example/{{item.key}}/{{item.value}}.json') }}"
status_code:
- 200
- 404 # supposing it's the "normal" error case
body_format: json
headers:
Content-Type: "application/json"
Authorization: "Token {{ token.json.token }}"
loop: "{{ example | items2dict }}"
register: result
- name: update existing with POST
uri:
url: "{{url}}/api/{{item.item.key}}/"
method: POSTT
body: "{{ lookup('file', 'example/{{item.item.key}}/{{item.item.value}}.json') }}"
status_code: 200
body_format: json
headers:
Content-Type: "application/json"
Authorization: "Token {{ token.json.token }}"
loop: "{{ result.results | rejectattr('status', '200') }}" # filter out 200 status from previous task
