In a course create a new external tool activity using this data: * Launch URL: http://www.imsglobal.org/developers/LTI/test/v1p1/tool.php * Shared secret: secret * Consumer key: 12345 Log in as a student user and check that the external tool opens (you will see a blue page "IMS LTI 1.1 PHP Provider" with a Context Information section where you can see the data that has been sent to the external tool) As admin, enable "Mobile services": Plugins ► Web Services ► Mobile Create a Token for the student user: Click on Site administration ► Plugins ► Web services ► Manage tokens Next, download the two files attached, place them in a directory accessible in your server. Edit the client_lti_launch.php and change the request data (token, url, and the toolid that is the external tool instance id in the table mdl_lti). This file calls the remote WS mod_lti_get_tool_launch_data and then launch the LTI Request via POST Open the client_lti_launch.php in a different browser ( http://localhost/client_lti_launch.php ) Check that you see the same blue page with the same data (some data like the timestamp and nonce will be different but that's is ok)
