Collections api return Could not authenticate you

api

#1

I can use status update api, but the collections api always return Could not authenticate you. with the same oauth.

My question is, do I need to request for whitelisting as Collections API suggested? That link is a little old and the new collections about page has no information about the request.


#2

You no longer need to apply for whitelisting for the Collections API. It is more likely to be an issue with the way you’ve signed your request.


#3

I’m using OAuth Signature Generator from https://dev.twitter.com/rest/reference/post/collections/entries/curate page, and there I got the cURL command, and I added Content-Type: application/json header to the curl command, then tested it, still got the same error. You can check the screenshot below:
