    copied!<p>I'm having a real nightmare trying to get the PesaPal API to work for me using Ruby...</p> <p>I appreciate that it's probably not the most commonly used API but if there's anybody online here who has more experience using OAuth, and/or PHP experience who could offer a fresh pair of eyes I'd appreciate it.</p> <p>So the PesaPal developer site is here: <a href="http://developer.pesapal.com" rel="nofollow">http://developer.pesapal.com</a> Their <a href="http://developer.pesapal.com/how-to-integrate/api-reference" rel="nofollow">API docs</a> don't give away too many clues about how to use OAuth with their site and I don't understand PHP well enough to be sure I've read their <a href="http://developer.pesapal.com/how-to-integrate/php-sample" rel="nofollow">PHP sample</a> correctly.</p> <p>Here's my attempt at implementing this in Ruby:</p> <pre><code>require 'oauth' require 'uri' key = '&lt;my sandbox key&gt;' sec = '&lt;my sandbox secret&gt;' API_DOMAIN = 'https://demo.pesapal.com' # An XML string of param data to include with our request RAW_XML = %{&lt;?xml version=\"1.0\" encoding=\"utf-8\"?&gt;&lt;PesapalDirectOrderInfo xmlns:xsi=\"http://www.w3.org/2001/XMLSchemainstance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" Amount=\"12.34\" Description=\"Bob Test 1\" Type=\"MERCHANT\" Reference=\"808\" FirstName=\"Bo\" LastName=\"Tester\" Email=\"bodacious@bodacious.com\" xmlns=\"http://www.pesapal.com\" /&gt;} # Escape the XML @post_xml = URI.escape(RAW_XML) # Create a new OAuth Consumer @consumer = OAuth::Consumer.new(key, sec, { site: API_DOMAIN, scheme: :query_string }) # The signed request object @signed_request = @consumer.create_signed_request('get', "#{API_DOMAIN}/API/PostPesapalDirectOrderV4") # Join the pesapal_request_data and oauth_callback with '&amp;' for valid URL params @params = { oauth_callback: URI.escape('http://localhost:3000'), pesapal_request_data: @post_xml, }.map { |k,v| "#{k}=#{v}" }.join('&amp;') # This is the URL we should redirect to puts redirect_url = "#{@signed_request.path}&amp;#{@params}" </code></pre> <p>When I try to visit the URL returned by this code, I get: <code>Problem: signature_invalid | Advice: &gt; |</code> back from the API.</p> <p>Can anyone think of what I'm doing wrong here?</p> <p>Thanks</p>
