+# Bulk API Overview
+
+Bulk API endpoints allows to perform bulk operations in single web request. There are currently following bulk api actions:
+- /api/v2/bulk/job_launch
+- /api/v2/bulk/host_create
+
+## Bulk Job Launch
+
+Provides feature in the API that allows a single web request to achieve multiple job launches. It creates a workflow job with individual jobs as nodes within the workflow job. It also supports providing promptable fields like inventory, credential etc.
+
+Following is an example of a post request at the /api/v2/bulk/job_launch
+
+```commandline
+{
+"name": "Bulk Job Launch",
+"jobs": [
+   {"unified_job_template": 7, "identifier":"foo", "limit": "kansas", "credentials": [1]},
+   {"unified_job_template": 8, "identifier":"bar", "inventory": 1, "execution_environment": 3},
+   {"unified_job_template": 9}
+]
+}
+```
+
+The above will launch a workflow job with 3 nodes in it. 
+
+## Bulk Host Create
+
+Provides feature in the API that allows a single web request to create multiple hosts in an inventory.  
+
+Following is an example of a post request at the /api/v2/bulk/host_create:
+
+```commandline
+{
+    "inventory": 1,
+    "hosts": [{"name": "host1", "variables": "ansible_connection: local"}, {"name": "host2"}, {"name": "host3"}, {"name": "host4"}, {"name": "host5"}, {"name": "host6"}]
+}
+```
+
+The above will add 6 hosts in the inventory.
