@joshwright10 thanks for opening this issue. I would like to explain that the endpoint in Terraform corresponds to the documentEndpoint in Azure API. Per the following resource JSON data in the Azure portal, the documentEndpoint should be "https://demo-cosmos-mangodb.documents.azure.com:443/", the mongoEndpoint should be "https://demo-cosmos-mangodb.mongo.cosmos.azure.com:443/". So the endpoint in Terraform is documentEndpoint instead of mongoEndpoint.

Terraform depends on the Azure API, the API does not expose property mongoEndpoint. Could you file an issue here requesting to expose mongoEndpoint if you need it? OncemongoEndpoint is available, terraform would follow up by priority.
