GET Search API 1.1 returns 401 error when used with geocode parameter

[sammazookie]

This works:
https://api.twitter.com/1.1/search/tweets.json?q=SpaceBabies&lang=en&result_type=mixed&count=10

Returns valid results.

This does not work:
https://api.twitter.com/1.1/search/tweets.json?q=SpaceBabies&lang=en&result_type=mixed&count=10&geocode=45.5236,122.6750,100mi

Returns the following error:
Error code: 401
{“errors”:[{“message”:“Could not authenticate you”,“code”:32}]}

I’ve tried various query terms. Since the first one works my code obviously authenticates OK. So why? Any ideas?

It’s likely that you need to encode the commas for the URL to be strictly valid.
