This tutorial shows how to upload files to Nexus using the Python programming language via the sync tasks upload endpoint. A script like this can be useful to periodically upload data sources to Nexus that are not connected to the internet or that only need refreshing every once in a while.

Info

This tutorial assumes that you have:

• Python installed on your computer
• obtained a valid Nexus Web API token (with Data Supplier role; see API Basics for more info)

Code

We use the 'requests' package for making the actual API calls.

```python import requests

base_url = "https://nexus.stellaspark.com/api/v1" token = "{web_api_token}"

Step 1: find the sync task ID for your uploadable data source

r = requests.get(f"{base_url}/sync_tasks/?uploadable=true&token={token}") r.raise_for_status() tasks = r.json()["results"]

sync_task_id = {sync_task_id} # Enter the sync task ID to upload to

Step 2: upload the file

with open("path/to/my_file.csv", "rb") as f: r = requests.post( f"{base_url}/sync_tasks/{sync_task_id}/upload/?token={token}", files={"upload_file": f}, ) r.raise_for_status() # Throw an error if something goes wrong ```
