Search All Datasets by Gateway Connection

Yes, you can use the Power BI REST API to search for all Power BI datasets using a specific gateway connection. Here's how:

1. Get the ID of the gateway connection you want to search for. You can do this by going to the Power BI service, clicking on the gear icon in the top right corner, selecting "Manage gateways," and then selecting the gateway you're interested in. The ID will be listed in the URL of the gateway page.

2. Use the Power BI REST API to get a list of all datasets in your organization. You can do this by sending a GET request to the following URL: https://api.powerbi.com/v1.0/myorg/datasets. You will need to provide an access token in the Authorization header of the request. You can get an access token using the steps outlined in the Power BI REST API documentation.

3. Loop through the list of datasets returned by the API and check the gatewayConnectionId property of each dataset. If the gatewayConnectionId matches the ID of the gateway you're interested in, then that dataset is using the specified gateway.

Here's an example in Python using the requests library:

import requests

# Replace with your own values
gateway_id = "my-gateway-id"
access_token = "my-access-token"

# Get list of all datasets
url = "https://api.powerbi.com/v1.0/myorg/datasets"
headers = {"Authorization": f"Bearer {access_token}"}
response = requests.get(url, headers=headers)
datasets = response.json()["value"]

# Filter datasets by gateway ID
datasets_using_gateway = [d for d in datasets if d["gatewayConnectionId"] == gateway_id]

# Print list of dataset names
for dataset in datasets_using_gateway:
print(dataset["name"])

This code will print a list of all dataset names that are using the specified gateway. You can modify the code to perform different actions based on the list of datasets returned.
