Twitter authentication token returns forbidden

[verve]

I am using twitter api for Tags, Api is : https://api.twitter.com/1.1/trends/place.json?id=1

To use this api i use oath token api : https://api.twitter.com/oauth2/token

It works fine for 3-4 months but suddenly now api : https://api.twitter.com/oauth2/token gives forbidden so i don’t get any thing from Tag api https://api.twitter.com/1.1/trends/place.json?id=1

The api responce is : {“errors”:[{“code”:99,“message”:“Unable to verify your credentials”,“label”:“authenticity_token_error”}]}

I don’t know what is wrong ???

Is there any api limit or any setting in developer application in twitter??

Please help me to solve this, Thanks in advance.

Have you tried regenerating the token on your apps.twitter.com page? I don’t know why this would be happening, but the error basically is saying that your token has become invalid for some reason.
