+# azurerm_cosmosdb_sql_trigger
+
+Manages an SQL Trigger.
+
+## Example Usage
+
+```hcl
+data "azurerm_cosmosdb_account" "example" {
+  name                = "tfex-cosmosdb-account"
+  resource_group_name = "tfex-cosmosdb-account-rg"
+}
+
+resource "azurerm_cosmosdb_sql_database" "example" {
+  name                = "tfex-cosmos-db"
+  resource_group_name = data.azurerm_cosmosdb_account.example.resource_group_name
+  account_name        = data.azurerm_cosmosdb_account.example.name
+  throughput          = 400
+}
+
+resource "azurerm_cosmosdb_sql_container" "example" {
+  name                = "example-container"
+  resource_group_name = azurerm_cosmosdb_account.example.resource_group_name
+  account_name        = azurerm_cosmosdb_account.example.name
+  database_name       = azurerm_cosmosdb_sql_database.example.name
+  partition_key_path  = "/id"
+}
+
+resource "azurerm_cosmosdb_sql_trigger" "example" {
+  name         = "test-trigger"
+  container_id = azurerm_cosmosdb_sql_container.example.id
+  body         = "function trigger(){}"
+  operation    = "Delete"
+  type         = "Post"
+}
+```
+
+## Arguments Reference
+
+The following arguments are supported:
+* `name` - (Required) The name which should be used for this SQL Trigger. Changing this forces a new SQL Trigger to be created.
+
+* `container_id` - (Required) The id of the Cosmos DB SQL Container to create the SQL Trigger within. Changing this forces a new SQL Trigger to be created.
+
+* `body` - (Required) Body of the Trigger.
+
+* `operation` - (Required) The operation the trigger is associated with. Possible values are `All`, `Create`, `Update`, `Delete` and `Replace`.
+
+* `type` - (Required) Type of the Trigger. Possible values are `Pre` and `Post`.
+
+## Attributes Reference
+
+In addition to the Arguments listed above - the following Attributes are exported: 
+
+* `id` - The ID of the SQL Trigger.
+
+## Timeouts
+
+The `timeouts` block allows you to specify [timeouts](https://www.terraform.io/docs/configuration/resources.html#timeouts) for certain actions:
+
+* `create` - (Defaults to 30 minutes) Used when creating the SQL Trigger.
+* `read` - (Defaults to 5 minutes) Used when retrieving the SQL Trigger.
+* `update` - (Defaults to 30 minutes) Used when updating the SQL Trigger.
+* `delete` - (Defaults to 30 minutes) Used when deleting the SQL Trigger.
+
+## Import
+
+SQL Triggers can be imported using the `resource id`, e.g.
+
+```shell
+terraform import azurerm_cosmosdb_sql_trigger.example /subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/group1/providers/Microsoft.DocumentDB/databaseAccounts/account1/sqlDatabases/database1/containers/container1/triggers/trigger1
+```
