Cisco EOX APi - not authorize after validate genete a valid token

[Reddaj]

Hello all,

I a am trying to send this request :

curl --location --request GET 'https://api.cisco.com/supporttools/eox/rest/5/EOXByDates/1/2011-01-01/2015-12-31?responseencoding=xml' \

--header 'Authorization: Bearer 72jkyR9hF........QgYXwF' \

--header 'Content-Type: application/xml'

But I got this response:

Status 403 Forbidden
<h1>Not Authorized</h1>

I follow the steps for Authentication , I registered a new app and I sent a request with the client and secret to generate a token.

But it is not working. Do you have any suggestions?

Thanks,
