Follow the instruction in Paypal Developer 'make your first call':
curl https://api.sandbox.paypal.com/v1/oauth2/token \
-H "Accept: application/json" \
-H "Accept-Language: en_US" \
-u "EOJ2S-Z6OoN_le_KS1d75wsZ6y0SFdVsY9183IvxFyZp:EClusMEUk8e9ihI7ZdVLF5cZ6y0SFdVsY9183IvxFyZp" \
-d "grant_type=client_credentials"
It is working and get the expected result like the instruction states, but I prefer to use ruby curb gem:
require 'curl'
paypal_result = Curl::Easy.http_post("https://api.sandbox.paypal.com/v1/oauth2/token", "grant_type=client_credentials") do |http|
http.headers['Accept'] = "application/json"
http.headers['Accept-Language'] = "en_US"
http.username = "EOJ2S-Z6OoN_le_KS1d75wsZ6y0SFdVsY9183IvxFyZp:EClusMEUk8e9ihI7ZdVLF5cZ6y0SFdVsY9183IvxFyZp"
end
puts paypal_result.body_str
However I got the following:
{"error":"invalid_client","error_description":"The basic auth authorization header cannot be decoded"}
It is an error for sure, but what's wrong with my curb syntax? Any idea?
I can't tell you exactly what's wrong, but I can tell you how to see what's happening. Try putting it into verbose mode, so you can see what data and headers are actually being sent:
curl = Curl::Easy.new
# Make it verbose, prints to stderr
curl.verbose = true
paypal_result = curl.http_post("https://api.sandbox.paypal.com/v1/oauth2/token", "grant_type=client_credentials") do |http|
# etc.
end
You can compare with the CLI version by using the -v flag.
Hope that helps you discover the difference.
