How can I send in the webhook information stored in the app properties

[Jose A. Íñigo]

I have created an addon with a configuration page in which the user has to store a clienId and clientSecret. This credentials are sent to Jira Cloud using the REST API:

PUT /rest/atlassian-connect/1/addons/$addonKey/properties/apiCredentials

Besides the application uses the webhook module and I need that whenever an issue is created/updated the webhook sends the clientId/clientSecret params stored previously as app config parameters.

How can it be done?

My atlassian-connect.json:

{
  "key": "${addon.key}",
  "baseUrl": "xxx/",
  "name": "xxx",
  "authentication": {
    "type": "jwt"
  },
  "lifecycle": {
    "installed": "/installed",
    "uninstalled": "/uninstalled"
  },
  "scopes": ["READ","WRITE"],
  "modules": {
    "webhooks": [
      {
        "event": "jira:issue_created",
        "url": "/issues/created?project={project.key}&issue={issue.key}"
      },
      {
        "event": "jira:issue_updated",
        "url": "/issues/updated?project={project.key}&issue={issue.key}"
      }
    ],
    "adminPages": [
      {
        "url": "/admin",
        "name": {
          "value": "My Admin Page"
        },
        "key": "my-admin-page"
      }
    ],
    "configurePage": {
      "url": "/config",
      "name": {
        "value": "xxx"
      },
      "key": "my-config-page"
    }
  }
}
