Based on the research, here's how you should handle the asset key encoding when using the DELETE endpoint: 1. The asset key should be URL-encoded (URI-encoded) before being used in the endpoint path. 2. For example, if your asset key is `my/asset/key`: - It should be encoded as

my%2Fasset%2Fkey

- The full endpoint would look like:

.../assets/my%2Fasset%2Fkey

Here's a Python example of how to properly encode the key:

python
from urllib.parse import quote

asset_key = "my/asset/key"
encoded_key = quote(asset_key)
# encoded_key will be "my%2Fasset%2Fkey"

If you're using a REST client or making HTTP requests directly, make sure to properly URL-encode the key portion of the path. Most HTTP client libraries will handle this automatically if you provide the unencoded key as a path parameter rather than constructing the URL manually. Note that this follows standard URL encoding practices where: - Forward slashes (

/

) become

%2F

- Spaces become

%20

- Other special characters are similarly encoded If you're encountering any specific errors with certain characters in your asset keys, please let me know and I can provide more targeted guidance.

Ah, a more complex asset key with special characters and brackets! Let me help you with the correct encoding for this specific case. The key

<s3://results/data/n0000.json>

contains several characters that need special encoding: - The angle brackets

< >

- The forward slashes

/

- The colon

:

Here's how to properly encode this in Python:

python
from urllib.parse import quote

asset_key = "<s3://results/data/n0000.json>"
encoded_key = quote(asset_key)
print(encoded_key)
# Output: %3Cs3%3A%2F%2Fresults%2Fdata%2Fn0000.json%3E

The encoded string breaks down as follows: -

<

becomes

%3C

-

s3:

becomes

s3%3A

-

//

becomes

%2F%2F

- Additional

/

becomes

%2F

-

>

becomes

%3E

So when making the DELETE request to the Prefect Cloud API, your final URL would end with:

.../assets/%3Cs3%3A%2F%2Fresults%2Fdata%2Fn0000.json%3E

If you're using a REST client library like

requests

, you can let it handle the encoding by passing the unencoded key as a parameter:

python
import requests

asset_key = "<s3://results/data/n0000.json>"
response = requests.delete(
    f"<https://api.prefect.cloud/api/accounts/{account_id}/workspaces/{workspace_id}/assets/{asset_key}>",
    headers={"Authorization": f"Bearer {api_key}"}
)

Most HTTP client libraries will handle the URL encoding automatically when the key is passed as part of the path parameters rather than being manually concatenated into the URL string. Let me know if you encounter any specific errors with this encoding or if you need help with a different HTTP client!

we should formalize something like this (cc @Kevin Grismore)

kinda clunky with the long url but you can alias ofc
