If you don't have an existing Pub/Sub topic, create a topic.\n To learn how to create a Pub/Sub topic, see\n [Managing topics and subscriptions](/pubsub/docs/admin).\n\n2. Make sure to configure the\n [`pubsubDestination`](/transcoder/docs/reference/rest/v1/JobConfig#FIELDS.pubsub_destination)\n field in the job configuration.\n\n {\n \"config\": {\n \"pubsubDestination\": {\n \"topic\": \"projects/\u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e/topics/\u003cvar translate=\"no\"\u003emy-topic-id\u003c/var\u003e\"\n }\n }\n }\n\n3. [Create a job](/transcoder/docs/how-to/jobs) to enable the\n [Google-managed Transcoder service account](/iam/docs/service-account-types#google-managed).\n\n4. Find the\n `service-`\u003cvar translate=\"no\"\u003ePROJECT_NUMBER\u003c/var\u003e`@gcp-sa-transcoder.iam.gserviceaccount.com`\n service account in the Google Cloud console, where\n \u003cvar translate=\"no\"\u003ePROJECT_NUMBER\u003c/var\u003e is the project number of the project you enabled\n the Transcoder API in and you plan to create the feed from.\n\n 1. In the Google Cloud console, go to the **IAM** page.\n\n [Go to IAM](https://console.cloud.google.com/iam-admin/iam/project)\n 2. Select the **Include Google-provided role grants** checkbox.\n\n5. Make sure the service account has the `pubsub.topics.publish` permission\n enabled.\n\nJob status reporting\n--------------------\n\nJob status is reported once the job fails or finishes successfully. No other\nstate changes are reported. Job status is reported using the `JobResult` message\nformat: \n\n Resource PubSubMessage\n {\n job: {\n object (JobResult)\n }\n }\n\n JobResult\n {\n name: string;\n state: string;\n error: {\n object (Status)\n }\n }\n\nFor more information, refer to the following:\n\n- [Job state](/transcoder/docs/reference/rest/v1/projects.locations.jobs#processingstate)\n- [Job status](/transcoder/docs/reference/rest/v1/projects.locations.jobs#status)\n- [Troubleshooting job errors](/transcoder/docs/troubleshooting)"]]
