+# CosmosDB Trigger
+
+The Azure Cosmos DB Trigger uses the Azure Cosmos DB Change Feed to listen for inserts and updates across partitions. The change feed publishes inserts and updates, not deletions.

+Full documentation can be found on

+
+# Events
+
+This setup describe how to write the data received, when someone
+accesses the Function App at `api/cosmos` via a `POST` request
+, to [Cosmos DB](https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-cosmosdb-v2#output---javascript-examples)
