How do I make the git repo and bucket-name a variable so that the values will be dynamic?

I am triggering a sensor from a webhook in argo events

I am making a post request which triggers the sensor and the sensor starts up the work flow

I want to get the data from body of the post request pass it to git repo

apiVersion: argoproj.io/v1alpha1
kind: Sensor
metadata:
  name: webhook
  namespace: argo-events
spec:
  template:
    serviceAccountName: operate-workflow-sa
  dependencies:

                    outputs:

webhook

apiVersion: argoproj.io/v1alpha1
kind: EventSource
metadata:
  name: webhook
  namespace: argo-events
spec:
  service:
    ports:
      - port: 12000
        targetPort: 12000
  webhook:
    example:
      port: "12000"
      endpoint: /deploy
      method: POST

Curl

curl -d '{"url":"https://github.com/not-real-name/ci-cd", "bucket-name": "app-2023"}' -H "Content-Type: application/json" -X POST http://localhost:12000/deploy`

I am getting this error

Failed: invalid spec: templates.git-clone: failed to resolve {{inputs.parameters.url}}

The url and bucket-name parameters need to be passed into git-clone:

spec:
  entrypoint: git-clone
  arguments:
    parameters:
      - name: url
        value: ""
      - name: bucket-name
        value: ""
  templates:
    - name: git-clone
      inputs:
        parameters:
          - name: url
          - name: bucket-name
        artifacts:
          - name: argo-source
            path: /src
            git:
              repo: "{{inputs.parameters.url}}"

Then the parameters are accessible within the git-clone template.
