Hey,

So if your Template looks like this, where you use a variable named “my\_variable”.

```json
{
  "steps": {
    "files_import": {
      "robot": "/http/import",
      "url": "${fields.my_variable}"
    }
  }
}

```

Then your Python code will look like the following to set the variable. You pass in a dictionary that represents the params field used by the Transloadit API. This dictionary contains a key for fields to allow for passing of custom variables. The documentation related to this is [here](https://transloadit.readthedocs.io/en/latest/transloadit.html#module-transloadit.assembly) for the Python SDK and as documented [here](https://transloadit.com/docs/api/#resource-assemblies) under “Supported keys inside the params field”

```python
from transloadit import client

tl = client.Transloadit('TRANSLOADIT_KEY', 'TRANSLOADIT_SECRET')
assembly_options = {
  "fields": {
     "my_variable": "https://transloadit.edgly.net/assets/images/home/robots.png"
   }
}
assembly = tl.new_assembly(options=assembly_options)
assembly_response = assembly.create(retries=5, wait=True)

print assembly_response.data.get('assembly_id')

```
