Importing Extended Tool Configurations

Standard LTI tool configurations can be manually entered by users in the Canvas UI, or set up via the external tools API. In the manual case, since many of the extensions listed here require more than a few lines of configuration, there is not currently an interface for extensions to be manually configured. Instead, we encourage tool providers to expose a set of URL endpoints that return standard configuration options for their tool services. Users are still required to enter their consumer key and shared secret manually, but the rest of the configuration should be standard enough that it can be reused for all users.

If providing a URL configuration endpoint is not an option, you can also provide your users with raw XML that they can paste in for configuration.

The configuration format is the same format used to import external tools using Common Cartridge. Examples of valid XML configuration snippets are found below.

Link Selection External Tool Examples

Remember, best practice is for link selection tools to have domain-level matching, and to only return URLs matching that domain.

Test Environment Setting Examples

External tools can support different LTI environments for different canvas environments.

Additionally, the domain and launch_urls can be set for each canvas environment by specifying the environment as part of the property name (ie, test_launch_url, beta_domain, etc). When used in this manner, specific environment properties take precedent over the default values.

NOTE: Test environment settings are established during the refresh process when the environments are mirrored from production.

Combined External Tool Configuration Examples

External tools can support multiple extensions in a single tool since each extension will have its own tool launch URL. Remember, though, that link selection tools should have domain-level matching set, and URLs returned by the service should be scoped to the matching domain.

Launch URL's containing query parameters

By default, Canvas handles LTI launch URLs with query parameters by including the query parameters in the URL and the post body. This can result in a signature mismatch if not accounted for. The oauth_compliant parameter allows an external tool provider to specify how it wants Canvas to handle launch URLs with query parameters: if set to true LTI query parameters will not be copied to the POST body.

Do not move LTI query params to POST body

Inside the options block there are two properties providing urls for initiating imports and exports of course based content, export_start_url and import_start_url respectively.

Export process

Both the export and import processes are designed to be asynchronous; to start the export process your application will receive a POST request to the specified export_start_url. The request body will contain tool_consumer_instance_guid, context_id, and any variable expansions requested (excluding user info and URLs). For authentication a JWT will be included in the Authorization header using the Bearer scheme, it is signed using the shared secret for the tool and will include the stored consumer key in the kid field of the token's header object.

If any action needs to performed by the tool it MUST respond with a success HTTP status code and the body MUST include two urls, one for checking the progress of the export and one to retrieve the JSON to be returned to the tool upon import. In the event there is nothing to be exported respond with an empty JSON object as the body or a 4xx status code. Any status codes aside from 200 and 201 in responses will be treated as though there is nothing to be returned upon import.

Example export start response

{
  "status_url": "https://lti.example.com/export/42/status",
  "fetch_url": "https://lti.example.com/export/42"
}

The status_url will be polled to determine when the content should be retreived. The response MUST include a status key; this key will be used to determine when the tool considers the export process to be completed whether it has been successful or not. When this field contains complete Canvas will then attempt to use the fetch_url to retrieve the exported data. In the case of failure set the status field to failed and supply a message field for display to the user.

Example in progress status response

{"status":"processing"}

Example failed status response

{"status":"failed", "message":"The content is not able to be copied due to copyright restrictions."}

Example complete success status response

{"status":"completed"}

Exporting a Subset of Course Content

If the user has chosen to migrate a subset of the source course's content an this will be indicated to the tool by inclusion of an additional field in the post body called custom_exported_assets. This will be an array of asset identifiers in the form of <asset type key>_<asset_id> (e.g. assignment_42) these use the same mappings as exported identifiers below. In the event that a tool provider has no content to export for a subset export either return an empty JSON object in the response or a status code outside the 200 range.

Exported Data Including Canvas Record IDs.

If in the process of importing your tool needs to receive record identifers for newly created items in Canavs the source IDs may be included in the export data with keys matching the pattern /^\$canvas_(\w+)_id$/. Example export data including an assignment ID with the orignial being assignment #42 and the newly created one for import being #84.

Exported data:

{
  assignments: [{"id":afd24c, "$canvas_assignment_id":42}]
}

Data returned on import:

{
  assignments: [{"id":afd24c, "$canvas_assignment_id":84}]
}

Additional expansions are available, for the most up to date list see [Canvas::Migration::ExternalContent::Translator::TYPES_TO_CLASSES](https://github.com/instructure/canvas-lms/blob/stable/lib/canvas/migration/external_content/translator.rb#L40)

Import process

To start the import process your application will receive a POST request to the specified import_start_url. The request body will contain tool_consumer_instance_guid, context_id, any variable expansions requested (excluding user info and URLs), and the content to be imported will be included in the data field of the posted form. Authentication will be handled in the same way as the export process.

The JSON response must include a status_url field which is used in the same manner as the same field in the export start response.
