Query parameters not properly URL-encoded (pandas data pipeline) #9DescriptionQuery parameters not properly URL-encoded (pandas data pipeline)
Description
Special characters break API calls when used in data pipelines.
Code snippet
params = {
"denominazione": "azienda & co"
}
response = client.request(
"GET",
base_url,
"/advance",
params=params
)
Observed behavior
400 Bad Request due to invalid encoding. ActivityIlyasFardaouix commented on Mar 19, 2026 I think the root cause here might be related to the client.request method, which is using the params dictionary directly without URL-encoding the query parameters. IIRC, the requests library (which is likely being used under the hood) expects the query parameters to be passed as a dict with the keys being the parameter names and the values being the parameter values. However, it does not automatically URL-encode the values. You might want to try using the urllib.parse.urlencode function to encode the params dictionary before passing it to the client.request method. Reacted by Francesco Bianco (yafb) francescobianco commented on Mar 24, 2026 Good point, thanks @IlyasFardaouix for looking into it.
We’re currently experimenting with a slightly different approach using Pandas for handling responses, so this area is still evolving on our side.
Any suggestions or experiments around improving the decoding/handling flow are more than welcome — feel free to share ideas or even open follow-up PRs.

Even though this seems to fix the issue, we’ll keep it open for now so we can run some internal tests in our environment over the next few months.
Once everything is fully verified and confirmed as stable, we’ll proceed with closing the issue.
Thanks again for your collaboration! Deadpool2000 commented on Apr 15, 2026 francescobianco commented on May 12, 2026 Deadpool2000 commented on May 12, 2026 @francescobianco thanks for the mention, happy to see it all make it into the release 😊
