Content Migrations API

API for accessing content migrations and migration issues

A MigrationIssue object looks like:

{
  // the unique identifier for the issue
  "id": 370663,
  // API url to the content migration
  "content_migration_url": "https://example.com/api/v1/courses/1/content_migrations/1",
  // Description of the issue for the end-user
  "description": "Questions in this quiz couldn't be converted",
  // Current state of the issue: active, resolved
  "workflow_state": "active",
  // HTML Url to the Canvas page to investigate the issue
  "fix_issue_html_url": "https://example.com/courses/1/quizzes/2",
  // Severity of the issue: todo, warning, error
  "issue_type": "warning",
  // Link to a Canvas error report if present (If the requesting user has
  // permissions)
  "error_report_html_url": "https://example.com/error_reports/3",
  // Site administrator error message (If the requesting user has permissions)
  "error_message": "admin only message",
  // timestamp
  "created_at": "2012-06-01T00:00:00-06:00",
  // timestamp
  "updated_at": "2012-06-01T00:00:00-06:00"
}

A ContentMigration object looks like:

{
  // the unique identifier for the migration
  "id": 370663,
  // the type of content migration
  "migration_type": "common_cartridge_importer",
  // the name of the content migration type
  "migration_type_title": "Canvas Cartridge Importer",
  // API url to the content migration's issues
  "migration_issues_url": "https://example.com/api/v1/courses/1/content_migrations/1/migration_issues",
  // attachment api object for the uploaded file may not be present for all
  // migrations
  "attachment": "{"url"=>"https://example.com/api/v1/courses/1/content_migrations/1/download_archive"}",
  // The api endpoint for polling the current progress
  "progress_url": "https://example.com/api/v1/progress/4",
  // The user who started the migration
  "user_id": 4,
  // Current state of the content migration: pre_processing, pre_processed,
  // running, waiting_for_select, completed, failed
  "workflow_state": "running",
  // timestamp
  "started_at": "2012-06-01T00:00:00-06:00",
  // timestamp
  "finished_at": "2012-06-01T00:00:00-06:00",
  // file uploading data, see {file:file.file_uploads.html File Upload
  // Documentation} for file upload workflow This works a little differently in
  // that all the file data is in the pre_attachment hash if there is no
  // upload_url then there was an attachment pre-processing error, the error
  // message will be in the message key This data will only be here after a create
  // or update call
  "pre_attachment": "{"upload_url"=>"", "message"=>"file exceeded quota", "upload_params"=>{}}"
}

A Migrator object looks like:

{
  // The value to pass to the create endpoint
  "type": "common_cartridge_importer",
  // Whether this endpoint requires a file upload
  "requires_file_upload": true,
  // Description of the package type expected
  "name": "Common Cartridge 1.0/1.1/1.2 Package",
  // A list of fields this system requires
  "required_settings": ["source_course_id"]
}

Scope: url:POST|/api/v1/users/:user_id/content_migrations

Create a content migration. If the migration requires a file to be uploaded the actual processing of the file will start once the file upload process is completed. File uploading works as described in the File Upload Documentation except that the values are set on a *pre_attachment* sub-hash. For migrations that don't require a file to be uploaded, like course copy, the processing will begin as soon as the migration is created. You can use the Progress API to track the progress of the migration. The migration's progress is linked to with the _progress_url_ value. The two general workflows are: If no file upload is needed: 1. POST to create 2. Use the Progress specified in _progress_url_ to monitor progress For file uploading: 1. POST to create with file info in *pre_attachment* 2. Do file upload processing using the data in the *pre_attachment* data 3. GET the ContentMigration 4. Use the Progress specified in _progress_url_ to monitor progress (required if doing .zip file upload)

Request Parameters:

Parameter		Type	Description
migration_type	Required	string	The type of the migration. Use the Migrator endpoint to see all available migrators. Default allowed values: canvas_cartridge_importer, common_cartridge_importer, course_copy_importer, zip_file_importer, qti_converter, moodle_converter
pre_attachment[name]		string	Required if uploading a file. This is the first step in uploading a file to the content migration. See the File Upload Documentation for details on the file upload workflow.
pre_attachment[*]		string	Other file upload properties, See File Upload Documentation
settings[file_url]		string	A URL to download the file from. Must not require authentication.
settings[content_export_id]		string	The id of a ContentExport to import. This allows you to import content previously exported from Canvas without needing to download and re-upload it.
settings[source_course_id]		string	The course to copy from for a course copy migration. (required if doing course copy)
settings[folder_id]		string	The folder to unzip the .zip file into for a zip_file_import.
settings[overwrite_quizzes]		boolean	Whether to overwrite quizzes with the same identifiers between content packages.
settings[question_bank_id]		integer	The existing question bank ID to import questions into if not specified in the content package.
settings[question_bank_name]		string	The question bank to import questions into if not specified in the content package, if both bank id and name are set, id will take precedence.
settings[insert_into_module_id]		integer	The id of a module in the target course. This will add all imported items (that can be added to a module) to the given module.
settings[insert_into_module_type]		string	If provided (and +insert_into_module_id+ is supplied), only add objects of the specified type to the module. Allowed values: `assignment`, `discussion_topic`, `file`, `page`, `quiz`
settings[insert_into_module_position]		integer	The (1-based) position to insert the imported items into the course (if +insert_into_module_id+ is supplied). If this parameter is omitted, items will be added to the end of the module.
settings[move_to_assignment_group_id]		integer	The id of an assignment group in the target course. If provided, all imported assignments will be moved to the given assignment group.
settings[importer_skips]		Array	Set of importers to skip, even if otherwise selected by migration settings. Allowed values: `all_course_settings`, `visibility_settings`
settings[import_blueprint_settings]		boolean	Import the "use as blueprint course" setting as well as the list of locked items from the source course or package. The destination course must not be associated with an existing blueprint course and cannot have any student or observer enrollments.
date_shift_options[shift_dates]		boolean	Whether to shift dates in the copied course
date_shift_options[old_start_date]		Date	The original start date of the source content/course
date_shift_options[old_end_date]		Date	The original end date of the source content/course
date_shift_options[new_start_date]		Date	The new start date for the content/course
date_shift_options[new_end_date]		Date	The new end date for the source content/course
date_shift_options[day_substitutions][X]		integer	Move anything scheduled for day 'X' to the specified day. (0-Sunday, 1-Monday, 2-Tuesday, 3-Wednesday, 4-Thursday, 5-Friday, 6-Saturday)
date_shift_options[remove_dates]		boolean	Whether to remove dates in the copied course. Cannot be used in conjunction with shift_dates.
selective_import		boolean	If set, perform a selective import instead of importing all content. The migration will identify the contents of the package and then stop in the +waiting_for_select+ workflow state. At this point, use the List items endpoint to enumerate the contents of the package, identifying the copy parameters for the desired content. Then call the Update endpoint and provide these copy parameters to start the import.
select		Hash	For +course_copy_importer+ migrations, this parameter allows you to select the objects to copy without using the +selective_import+ argument and +waiting_for_select+ state as is required for uploaded imports (though that workflow is also supported for course copy migrations). The keys are object types like 'files', 'folders', 'pages', etc. The value for each key is a list of object ids. An id can be an integer or a string. Multiple object types can be selected in the same call. Allowed values: `folders`, `files`, `attachments`, `quizzes`, `assignments`, `announcements`, `calendar_events`, `discussion_topics`, `modules`, `module_items`, `pages`, `rubrics`

PUT /api/v1/users/:user_id/content_migrations/:id

Scope: url:PUT|/api/v1/users/:user_id/content_migrations/:id

Update a content migration. Takes same arguments as create except that you can't change the migration type. However, changing most settings after the migration process has started will not do anything. Generally updating the content migration will be used when there is a file upload problem, or when importing content selectively. If the first upload has a problem you can supply new _pre_attachment_ values to start the process again. Returns a ContentMigration object

GET /api/v1/users/:user_id/content_migrations/:id/selective_data

Scope: url:GET|/api/v1/users/:user_id/content_migrations/:id/selective_data

Enumerates the content available for selective import in a tree structure. Each node provides a +property+ copy argument that can be supplied to the Update endpoint to selectively copy the content associated with that tree node and its children. Each node may also provide a +sub_items_url+ or an array of +sub_items+ which you can use to obtain copy parameters for a subset of the resources in a given node. If no +type+ is sent you will get a list of the top-level sections in the content. It will look something like this: [{ "type": "course_settings", "property": "copy[all_course_settings]", "title": "Course Settings" }, { "type": "context_modules", "property": "copy[all_context_modules]", "title": "Modules", "count": 5, "sub_items_url": "http://example.com/api/v1/courses/22/content_migrations/77/selective_data?type=context_modules" }, { "type": "assignments", "property": "copy[all_assignments]", "title": "Assignments", "count": 2, "sub_items_url": "http://localhost:3000/api/v1/courses/22/content_migrations/77/selective_data?type=assignments" }] When a +type+ is provided, nodes may be further divided via +sub_items+. For example, using +type=assignments+ results in a node for each assignment group and a sub_item for each assignment, like this: [{ "type": "assignment_groups", "title": "An Assignment Group", "property": "copy[assignment_groups][id_i855cf145e5acc7435e1bf1c6e2126e5f]", "sub_items": [{ "type": "assignments", "title": "Assignment 1", "property": "copy[assignments][id_i2102a7fa93b29226774949298626719d]" }, { "type": "assignments", "title": "Assignment 2", "property": "copy[assignments][id_i310cba275dc3f4aa8a3306bbbe380979]" }] }] To import the items corresponding to a particular tree node, use the +property+ as a parameter to the Update endpoint and assign a value of 1, for example: copy[assignments][id_i310cba275dc3f4aa8a3306bbbe380979]=1 You can include multiple copy parameters to selectively import multiple items or groups of items.

Request Parameters:

Parameter		Type	Description
type		string	The type of content to enumerate. Allowed values: `context_modules`, `assignments`, `quizzes`, `assessment_question_banks`, `discussion_topics`, `wiki_pages`, `context_external_tools`, `tool_profiles`, `announcements`, `calendar_events`, `rubrics`, `groups`, `learning_outcomes`, `attachments`

Get asset id mapping ContentMigrationsController#asset_id_mapping

GET /api/v1/courses/:course_id/content_migrations/:id/asset_id_mapping

Scope: url:GET|/api/v1/courses/:course_id/content_migrations/:id/asset_id_mapping

Given a complete course copy or blueprint import content migration, return a mapping of asset ids from the source course to the destination course that were copied in this migration or an earlier one with the same course pair and migration_type (course copy or blueprint). The returned object's keys are asset types as they appear in API URLs (+announcements+, +assignments+, +discussion_topics+, +files+, +module_items+, +modules+, +pages+, and +quizzes+). The values are a mapping from id in source course to id in destination course for objects of this type.

Example Request:

curl https://<canvas>/api/v1/courses/<course_id>/content_migrations/<id>/asset_id_mapping \
    -H 'Authorization: Bearer <token>'

Example Response:

{
  "assignments": {"13": "740", "14": "741"},
  "discussion_topics": {"15": "743", "16": "744"}
