Before upgrade : Prerequisites SMTP setup for the site, perhaps using mailcatcher. Run your site with public access (use ngrok or similar) Create 3 badgr account on badgr.io (US) Account 1 as Admin (Use as system badge account) Account 2 and 3 as Student/Regular user accounts Create another account on eu.badgr.io (Use as user badge account) An admin and 5 students available in the system. Setup badges for the Moodle site as described here :  In "Site administration / Badges / Badges settings", set the issuer site backpack with Badgr Account1 In "Site administration / Badges / Manage backpacks", edit the https://badgri.io  backpack and set the password. As student1, go to "Dashboard / Preferences / Badges / Backpack settings", connect Badgr (ussing Account2) and set it to a 'Connected' state (you'll need to check the email to verify the account). OAuth2 setup for OBv2.1 Login as admin. Access to the "Site home" and "Turn editing on". Add a label, upload an image there and save changes. Right-click over the uploaded image and copy the image address. You'll need to replace "https://471f8462.ngrok.io/m/stable_master/pluginfile.php/41/mod_label/intro/logo.png" of the next command to the copied image URL. Register the oAuth2 service in the IMS Global IdentityServer4 executing the following command, replacing "https://471f8462.ngrok.io/" by your server URL. You'll probably need to adapt "https://471f8462.ngrok.io/m/stable_master/" to your Moodle URL: curl --location --insecure --request POST 'https://dc.imsglobal.org/obauth/connect/register' \ --header 'Accept: application/json' \ --header 'Content-Type: application/json' \ --data-raw ' { "client_name": "Badge Moodle", "client_uri": "https://471f8462.ngrok.io/", "logo_uri": "https://471f8462.ngrok.io/m/stable_master/pluginfile.php/41/mod_label/intro/logo.png", "tos_uri": "https://471f8462.ngrok.io/", "policy_uri": "https://471f8462.ngrok.io/", "software_id": "stablemaster-testing", "software_version": "2020041700.01", "redirect_uris": [ "https://471f8462.ngrok.io/m/stable_master/badges/oauth2callback.php" ], "token_endpoint_auth_method": "client_secret_basic", "grant_types": [ "authorization_code", "refresh_token" ], "response_types": [ "code" ], "scope": "https://purl.imsglobal.org/spec/ob/v2p1/scope/profile.update https://purl.imsglobal.org/spec/ob/v2p1/scope/profile.readonly https://purl.imsglobal.org/spec/ob/v2p1/scope/assertion.create https://purl.imsglobal.org/spec/ob/v2p1/scope/assertion.readonly offline_access" }' You should get a result like this. Copy the client_id and the client_secret (you'll need them to configure the oAuth2 service) { "client_id": "LGC8WEFTxp8", "client_secret": "3GAfOtFgflA", "client_id_issued_at": 1587110808, "client_secret_expires_at": 1618646808, "client_name": "Badge OU", "client_uri": "https://471f8462.ngrok.io/", "logo_uri": "https://471f8462.ngrok.io/m/stable_master-badges/pluginfile.php/41/mod_label/intro/robot-1214536_1920.png", "tos_uri": "https://471f8462.ngrok.io/", "policy_uri": "https://471f8462.ngrok.io/", "software_id": "13dcdc83-fc0d-4c8d-9159-6461da297388", "software_version": "54dfc83-fc0d-4c8d-9159-6461da297388", "redirect_uris": [ "https://471f8462.ngrok.io/m/stable_master/badges/oauth2callback.php" ], "token_endpoint_auth_method": "client_secret_basic", "grant_types": [ "authorization_code", "refresh_token" ], "response_types": [ "code" ], "scope": "https://purl.imsglobal.org/spec/ob/v2p1/scope/profile.update https://purl.imsglobal.org/spec/ob/v2p1/scope/profile.readonly https://purl.imsglobal.org/spec/ob/v2p1/scope/assertion.create https://purl.imsglobal.org/spec/ob/v2p1/scope/assertion.readonly offline_access" Go to "Site administration / Server / OAuth 2 services". Create a custom service with the following information: Name: "IMS Global" Client ID: <previous client_id> Client secret: <previous client_secret> Enable Authenticate token requests via HTTP headers Scopes included in a login request and Scopes included in a login request for offline access: "openid profile email" Service base URL: https://dc.imsglobal.org/obauth Logo URL: https://dc.imsglobal.org/obauth/icon.jpg   Save changes.  OBv2.1 setup - Create new backpack In Site admin -> Badges -> Manage backpacks Create a new backpack with the following details : Backpack API URL - https://dc.imsglobal.org/obprovider/ims/ob/v2p1 Backpack URL - https://dc.imsglobal.org API Version - Open Badges v2.1 OAuth2 services - IMS Global Save changes.
