  • Replace <your_sid> with your “Account sid”
  • Replace <subdomain> with the region of your account
    1. <subdomain> of Singapore cluster is @ccm-api.exotel.com
    2. <subdomain> of Mumbai cluster is @ccm-api.in.exotel.com
  • Replace <user_id> and <device_id> with the user's unique identifier and device identifier as present in GET user details API.

<your_api_key> , <your_api_token> and <your_sid> are available in the API settings page of your Exotel Dashboard

The following are the PUT parameters supported with Content-Type: application/json set in the header
