+### Parameterized checkpoint keys
+
+Checkpoint keys are required to manage the status of change data capture processes. For efficient management, you can parameterize the checkpoint key to allow connections to different sources. Here's how you can implement a parameterized checkpoint key:
+
+1. Create a global parameter to store the checkpoint key at the pipeline level to ensure consistency across executions:
+
+   ```json
+   "parameters": {
+    "checkpointKey": {
+        "type": "string",
+        "defaultValue": "YourStaticCheckpointKey"
+    }
+   } 
+   ```
+
+1. Programmatically set the checkpoint key to invoke the pipeline with the desired value each time it runs. Here's an example of a REST call using the parameterized checkpoint key:
+
+   ```json
+   PUT https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.DataFactory/factories/{factoryName}/pipelines/{pipelineName}?api-version=2018-06-01
+   Content-Type: application/json
+   {
+       "properties": {
+           "activities": [
+               // Your activities here
+           ],
+           "parameters": {
+               "checkpointKey": {
+                   "type": "String",
+                   "defaultValue": "YourStaticCheckpointKey"
+               }
+           }
+       }
+   }
+   ```
