401 responses when trying to subscribe to a feed to which user is already subscribed

[jbrayton]

Using this endpoint:

https://api.feedbin.com/v2/subscriptions.json

If I subscribe to a new feed, I get a 201 response as expected. However, if I try to subscribe to a feed to which I am already subscribed, I often get a 401 instead of a 302. I am replaying the request that I first used to subscribe.

I feel confident that my "Authorization" header is correct. Any idea why I would be getting a 401?

Hi @jbrayton,

Sorry for the trouble. Unfortunately I'm not able to reproduce this issue.

Can you reproduce this issue using curl or provide the complete HTTP request and response?

HTTP libraries often abstract the actual HTTP so it's tough to see where the error might be. The best way I've found for debugging client code is to use Charles.

Something like the following would be great. Keep in mind to blank out your credentials.

curl -svu '[email protected]:XXX' -H "Content-Type: application/json; charset=utf-8" -d '{"feed_url": "http://daringfireball.net/index.xml"}'  https://api.feedbin.com/v2/subscriptions.json
