Allow Batch access to your topic

In order to use a PubSub topic as a replay destination, you will need to allow our IAM user permissions to list/publish to your topic

First, open the topic you wish to replay to in Google Cloud's console

On the right-hand side, under the Permissions tab, click "+ Add Principal" button

Click Add Principal

Enter in our IAM user into the "New Principals" text box

IAM USER:

[e-mail]

Enter in our IAM user

In the "Select A Role" dropdown, select Pub/Sub -> Pub/Sub Publisher

Add Pub/Sub Publisher role

Then click "+ Add Another Role" and select Pub/Sub -> Pub/Sub Viewer.

Your permissions should then look like the following. Save the permissions.

Add both Pub/Sub Publisher and Pub/Sub Viewer roles

Streamdal's systems will now be able to publish messages to your topic!. Now we just setup the destination in Streamdal

Setup destination in Streamdal Console

Head on over to the Destinations page: https://console.streamdal.com/destinations
