The query should be similar to: http://qa.moodle.net/mod/lti/services.php/CourseSection/5/bindings/celtic-project.org/tdeQgAkvfqbmReC/1/memberships?limit=10&from=1 Click on the Read button Check the JSON in the response to ensure it correctly reports each user enrolled in the course - also check for a nextPage element and send a request to this endpoint to check that it properly gives the next set of members (only included when the limit option is used). The response should be similar to this: Service responseclose or Esc Key HTTP/1.1 200 OK Date: Wed, 04 Nov 2015 02:28:06 GMT Content-Type: application/vnd.ims.lis.v2.membershipcontainer+json;charset=UTF-8 Transfer-Encoding: chunked Connection: keep-alive Set-Cookie: __cfduid=d2d407d161d9b72947cc93b36ced477bc1446604086; expires=Thu, 03-Nov-16 02:28:06 GMT; path=/; domain=.moodle.net; HttpOnly Vary: Front-End-Https,Accept-Encoding,User-Agent Cache-Control: max-age=3600 Expires: Wed, 04 Nov 2015 03:28:06 GMT Server: cloudflare-nginx CF-RAY: 23fce2323a811061-CDG   { "@context" : "http://purl.imsglobal.org/ctx/lis/v2/MembershipContainer", "@type" : "Page", "@id" : "http://qa.moodle.net/mod/lti/services.php/CourseSection/5/bindings/celtic-project.org/tdeQgAkvfqbmReC/1/memberships", "nextPage" : "http://qa.moodle.net/mod/lti/services.php/CourseSection/5/bindings/celtic-project.org/tdeQgAkvfqbmReC/1/memberships?limit=10&from=11", "pageOf" : { "@type" : "LISMembershipContainer", "membershipSubject" : { "@type" : "Context", "contextId" : "5", "membership" : [ {"status":"Active","member":{"userId":"37","sourcedId":"","name":"Student 30","givenName":"Student","familyName":"30","email":"student30@example.com"},"role":["Learner"]}, {"status":"Active","member":{"userId":"38","sourcedId":"","name":"Student 31","givenName":"Student","familyName":"31","email":"student31@example.com"},"role":["Learner"]}, {"status":"Active","member":{"userId":"39","sourcedId":"","name":"Student 32","givenName":"Student","familyName":"32","email":"student32@example.com"},"role":["Learner"]}, {"status":"Active","member":{"userId":"40","sourcedId":"","name":"Student 33","givenName":"Student","familyName":"33","email":"student33@example.com"},"role":["Learner"]}, {"status":"Active","member":{"userId":"41","sourcedId":"","name":"Student 34","givenName":"Student","familyName":"34","email":"student34@example.com"},"role":["Learner"]}, {"status":"Active","member":{"userId":"42","sourcedId":"","name":"Student 35","givenName":"Student","familyName":"35","email":"student35@example.com"},"role":["Learner"]}, {"status":"Active","member":{"userId":"43","sourcedId":"","name":"Student 36","givenName":"Student","familyName":"36","email":"student36@example.com"},"role":["Learner"]}, {"status":"Active","member":{"userId":"44","sourcedId":"","name":"Student 37","givenName":"Student","familyName":"37","email":"student37@example.com"},"role":["Learner"]}, {"status":"Active","member":{"userId":"45","sourcedId":"","name":"Student 38","givenName":"Student","familyName":"38","email":"student38@example.com"},"role":["Learner"]}, {"status":"Active","member":{"userId":"46","sourcedId":"","name":"Student 39","givenName":"Student","familyName":"39","email":"student39@example.com"},"role":["Learner"]} ] } } }
