Sending requests to nodes

Send a test request to a node from the DataSphere interface:

1. Select the relevant project in your community or on the DataSphere homepage in the Recent projects tab.

2. Under Project resources, select Node.
3. Select the node to send a request to.
4. Go to the Request tab.
5. Under Create test request, in the Input field, enter the request input variables in {"a":2,"b":3} format and click Execute.
6. View the request processing results under Response.

To send requests to nodes, you must have the datasphere.user or datasphere.admin role for the folder where the project and node were created.

Sample gRPC API callSample gRPC API call

grpcurl \
  -H "Authorization: Bearer <IAM_token>" \
  -d '{
  "folder_id": "<folder_ID>",
  "node_id": "<node_ID>",
  "input": { <input_variables> } \
  }' \
  datasphere.api.cloud.yandex.net:443
yandex.cloud.datasphere.v1.NodeService/Execute

Where:

• <IAM_token>: IAM token used for authentication.
• <folder_ID>: ID of the folder the project and node are created in.
• <node_ID>: Node ID.
• <input_variables>: Object where keys match input variables.

In a successful response, the object is returned:

{
   "output": {
      <output_variables>
   }
}

Where <output_variables> is the object in which keys match output variables.

You can use the cURL utility to send REST requests.

curl https://datasphere.api.cloud.yandex.net/datasphere/v1/nodes/<node_ID>:execute \
   --request POST \
   --header "Authorization: Bearer <IAM_token>"
   --data '{
      "folder_id": "<folder_ID>",
      "node_id": "<node_ID>",
      "input": { <input_variables> }
   }'

Where:

• <IAM_token>: IAM token used for authentication.
• <folder_ID>: ID of the folder the project and node are created in.
• <node_ID>: Node ID.
• <input_variables>: Object where keys match input variables.

The response returns a JSON object with output variables.
