# See Global Unlock Sample for sample code.

# Use your API key and secret here...

# Let's test the JWT to by sending the following request:

# curl --request GET \

# curl --request GET \

#   --header 'authorization: Bearer { your_token }' \
#   --header 'content-type: application/json

# Use the following online tool to generate HTTP code from a CURL command
# Convert a cURL Command to HTTP Source Code

$http.SetRequestHeader("content-type","application/json")
# Adds the "Authorization: Bearer { your_token }" header.
