"Can't authenticate you" error when trying to run a DigitalOcean API command

I tried to run this command for rebuilding my droplet:

curl -X POST "" \
-H "Content-Type: application/json" \
-H "Authorization: Bearer MY_API_TOKEN" \
-d '{"type":"rebuild","image":"ubuntu-16-04-x64"}' 

Note I used MY_DROPLET_ID, taken from my Note I used MY_API_TOKEN (read and write), taken from

I’d like to know what’s bad with my command? I might missed something aside of droplet-ID and API-token.

Javier from the DO support team helped me with this. I’ll now quote his response:

I appreciate you contacting us with this issue. Sorry to hear about this case. Currently, the “Can’t authenticate you” error specifically is with the failure to accept the token being passed in.

The format is correct here, so the only thing I can think of is either the key is missing or something has caused the key to be expired.

Indeed, like Javier said, the problem was with the API token. I created a new token and then the operation succeeded.

I also experienced the same issue but resolved it by regenerating a new API token and then echo token-key in my local machine from any location. Voila!!!
