# Get Document Information

## cURL

Use the following cURL command to get label sets added to a project. You can copy and paste the following template and replace the access\_token and the content of the label set items according to your needs.

```javascript
curl --location --request POST 'https://datasaur.ai/graphql' \
  --header 'Authorization: Bearer a29a6b20588b7a350395a0b8942642cfbf33926c' \
  --header 'Content-Type: application/json' \
  --data-raw '{ "operationName": "GetProjectDocumentQuery", "query": "query GetProjectDocumentQuery($documentId: ID!) { document: getTextDocument(fileId: $documentId) { id signature fileName } }", "variables": { "documentId": "c541e403-776a-40b7-af4b-955c7be86c0d" }}'
```

Below is a more readable version of the above curl command's request body.

```javascript
{
    "operationName": "GetProjectDocumentQuery",
    "query": "query GetProjectDocumentQuery($documentId: ID!) { document: getTextDocument(fileId: $documentId) { id signature fileName } }",
    "variables": {
        "documentId": "c541e403-776a-40b7-af4b-955c7be86c0d"
    }
}
```

* **operationName**: you can use any alphanumeric string in as the operationName. Refer [this page](https://graphql.org/learn/queries/#operation-name) for best practices on choosing an `operationName` .
* **variables:**
  * **documentId:** string, the document ID of the reviewer for the project.
* **query**: Copy this from the example above.

💡a **tag** has the same meaning as **label**. In the near future, we will update the GraphQL Schema to refer to all instances as labels.

## Response

Here is the response you can expect after issuing the cURL command. Use the **id** to create the project.

```javascript
{
    "data": {
        "document": {
            "id": "c541e403-776a-40b7-af4b-955c7be86c0d",
            "signature": "fab4a116af4da9d2381e61e8bf2337170d8d044704c4d679f439a79a04d7bddb",
            "fileName": "Hamlet.txt"
        }
    },
    "extensions": {}
}
```

* **id**: the unique ID of the document
* **signature**: hash of the document. The value will change when the content (sentence or tokens) of the document changes.
* **fileName**: the name of the file
