'Execute a ansible playbook if other playbooks fails

I have multiple play books, I have to run create_silence.yml at the starting of the execution and delete_silence.yml at the last, which I'm able to do.

But after create_silence.yml if any playbook fails delete_silence.yml should execute whatever the case is.

Below is delete_silence.yml

- hosts: all
  tasks:
    - name: Executing block for silencing an alert
      block: 
        - name: block for deleting silence
          block:  
            - name: delete silence
              uri: 
                url: http://127.0.0.1:9093/alert-manager/api/v2/silence/{{silence_id}}
                method: DELETE
                HEADER_Content-Type: "application/json"
                status_code: 200
              delegate_to :  "{{ admin_server }}"
              register : delete_silence_output
          ignore_errors: true     
          when: env is search("PROD") or env is search("PSE") or env is search("QA1")

Below is main.yml

- import_playbook: create_silence.yml
  when: job_type is search("REMOVE")  or job_type is search("DEPLOY")
- import_playbook: Remove.yml
  when: job_type is search("REMOVE")
- import_playbook: Deploy.yml
  when: job_type is search("DEPLOY")
- import_playbook: delete_silence.yml
  when: job_type is search("REMOVE")  or job_type is search("DEPLOY")

So if any task fails in Deploy.yml or Remove.yml , delete_silence.yml should execute

Thanks in advance

My suggestion is that you transform your create_silence, Remove, Deploy and delete_silence playbooks into roles and call those roles either from independent playbooks or 1 playbook only using a state variable.

If you call the create_silence role from the create playbook you can add a block/rescue block to catch errors and call the delete_silence role.

Something like this...

- hosts: all
  tasks:
    block: 
      - name: "Call create_silence role"
        import_role:
          name: 'create_silence'
    rescue:
      - name: "Call delete_silence role"
        import_role:
          name: 'delete_silence'
