The webhook will be a POST request where the request body is the same as the response body of the [get prediction](https://docs.quickqr.art/apis/http-api-reference/predictions#get-a-prediction) operation. If there are network problems, we will retry the webhook a few times, so make sure it can be safely called more than once. |
