DataLink provides API help documentation and API helper built in with some useful capabilities that can help making edits to connectors programmatically.

Here is an example of using API to make a change to SOAP connector. 

1. Open the manager, click on an agent and then an existing DataLink connector.
   Make note of  the URL. It contains:
   • Agent ID (first set of numbers in the URL)
   • Connector ID (second set of numbers in the URL)
     
2. In new browser tab, access the API Helper by adding "/api" at the end of URL. 
3. Get the connector's details. 
   • Click "agent{id}connector" then "/resource/agent/{id}/connector/{connectorId}".
   • Enter agent id and connector id from step 1 and click "Try it out!".
   • Copy the contents of Response Body and save with .json extension.
     These are all the settings for your connector.
4. To edit same connector, find "PUT /resource/agent/{id}/connector/{connectorId}"
5. Enter agent and connector IDs.
6. Paste the contents of .json file or output from retrieve connector details step.
7. Modify the values.
