How to Connect External Platform via LTI
LTI External tools are add-on applications that can be integrated directly into your LMS course. These tools may provide interactive content, learning activities, or assessments.
Trainers/Teachers can add and link to LTI activities from within the LMS course page, allowing students to access them seamlessly without leaving your LMS site or logging in to another system.
Depending on the tool and how it is configured, grades from these activities can also be automatically returned to the Moodle gradebook.

Adding LTI External Tools at Course Level (Supports LTI 1.0/1.1 and LTI 1.3)
Step 2: Click the Add tool button and fulfill all the needed details:
| Tool name | Used to identify the tool provider within LMS. The name entered will be visible to trainers when adding external tools within courses. |
| Tool URL | This is the URL for connecting to site. If your site uses SSL (is on HTTPS) you will only be able to use a tool that also uses SSL. Make sure the tool URL has HTTPS before attempting to use it or you may get a blank page. |
| Tool description | Used to describe what the tool is for, what it does, or any additional information the trainer may need to know. |
| LTI Version | LMS supports LTI 1.0/1.1 and 1.3 LTI versions |
| Consumer key (for LTI 1.0/1.1) | This tells the connecting LTI compliant site that you're allowed to connect. The "tool provider", i.e. the manager of the connecting LTI compliant site will issue you with this key. If you are merely linking to a tool with no secure access or gradebook sharing then you won't need a consumer key. If you are linking to a course or activity from another LMS site, then you can add any consumer key. |
| Shared secret (for LTI 1.0/1.1) | this is the "password" to connect to the tool - the LTI compliant site. |
Public key type (for LTI 1.3) | The authentication method used to validate the tool |
Public keyset (for LTI 1.3) | This is where your site will retrieve the tool's public key to allow signatures of incoming messages and service requests to be verified. |
Initiate login URL (for LTI 1.3) | The tool URL to which requests for initiating a login are to be sent. This URL is required before a message can be successfully sent to the tool. |
Redirections URI(s) (for LTI 1.3) | A list of URIs (one per line) which the tool uses when making authorisation requests. At least one must be registered before a message can be successfully sent to the tool. |
Custom parameters | Most times, you can leave this blank. The tool provider might use this to allow you to display a specific resource. |
Default launch container | This is how the external tool will be displayed. Embed - The content will appear within the activity page where the tool is used, not moving users away from the page, but hiding any blocks your course may have. Embed without blocks - The content will be displayed in the existing tab or window. Users will have to navigate back to the course using the ‘Back’ button once they’re done. Existing window - The content will be displayed in the existing tab or window. Users will have to navigate back to the course using the ‘Back’ button once they’re done. New Window - the external tool will open in a new window. (A new window or tab will open with the External tool and the old browser window containing the course page will not change.) |
Content selection URL | The Content Selection URL will be used to launch the content selection page from the tool provider. If it is empty, the Tool URL will be used. |
Icon URL | You can display a different icon from the default External Tool icon by entering its URL here |
Secure Icon URL | Enter the URL of a different icon here if your students are accessing your site securely via SSL. |
| IMS LTI Assignment and Grade Services | Whether to use the IMS LTI Assignment and Grade Services to synchronise grades instead of the Basic Outcomes service.
• Use this service for grade sync and column management - The service will be able to create and update gradebook columns and manage the grades. |
| IMS LTI Names and Role Provisioning | Allow the tool to retrieve members' info from the course using the IMS LTI Names and Role Provisioning Service. The privacy settings will apply. For course-level requests these will be based on the tool configuration settings. If you wish to always send such details, do not delegate the choice to trainers. Link-level requests will always use the privacy settings which apply to the link. |
| Tool Settings | Allow the tool to save and retrieve settings values. |
| Share launcher's name with tool | Specify whether the full name of the user launching the tool should be shared with the tool provider. The tool provider may need launchers' names to show meaningful information within the tool. |
| Share launcher's email with tool | Specify whether the e-mail address of the user launching the tool will be shared with the tool provider. The tool provider may need launcher's e-mail addresses to distinguish users with the same name in the UI or send e-mails to users based on actions within the tool. |
| Accept grades from the tool | Specify whether the tool provider can add, update, read, and delete grades associated with instances of this tool. Some tool providers support reporting grades back to Moodle based on actions taken within the tool, creating a more integrated experience. |
Force SSL (tickbox) | Selecting this option forces all launches to this tool provider to use SSL. In addition, all web service requests from the tool provider will use SSL. If using this option, confirm that this site and the tool provider support SSL. |
Mixed protocol limitations
If your LMS site instance is using HTTP (and not HTTPS) you will only be able to use the tool on sites that are also using HTTP (and not HTTPS). It's recommended that you use HTTPS on your Moodle instance. See Transitioning to HTTPS.
A required parameter (oauth_consumer_key) was missing
This exception occurs when the Tool Consumer is missing a Consumer Key parameter. As mentioned above, the consumer key can be anything you want so long as the field isn't left empty. Best keep it simple and without special characters, however.
User has free access to the entire site, isn't contained to the course
This can happen when the course content isn't embedded. Enable Allow frame embedding in Site Administration > Security > HTTP Security and, on the consumer site LTI tool settings, add force_embed=1 in the custom parameters settings.
This XML file does not appear to have any style information associated with it.
Some tool consumers do not support cartridge URLs such as Sakai and Chamilo, in that case, it's better to use the launch URL.
Invalid request
This exception can happen for various reasons, so it can be difficult to trace the root of the problem. One of the possibilities is that deep linking is enabled in the tool consumer. Disabling it can help in LMS that have it like Chamilo and Canvas.
