Provided is a group-based communication interface, on a computing device, configured to display a defined preview of a resource. The computing device receives a group-based message including a resource request that identifies a requested resource and a resource address. The computing device compares the resource address with a list of subscribed resource addresses and determines from the comparison of the resource address and the subscribed resource addresses that the resource address is associated with a resource provider and is thus a subscribed resource address. In response to determining that the resource address is the subscribed resource address, the computing device provides a defined preview request comprising authentication information to the resource provider, receives defined preview data from the resource provider, and renders the defined preview of the resource based on the defined preview data to the group-based communication interface associated with the group-based message.
