      Objects API

      The Objects API lets you migrate objects between Fusion instances by exporting and importing. Fusion objects include all your searchable data, plus pipelines, aggregations, and other configurations on which your collections depend.

      As an alternative in some cases, you can use the Fusion UI to migrate objects.

      For both the API and UI, migrating objects is intended for use within a specific Fusion version. A migrator tool is available for migrating objects from one Fusion version to a different one.

      You can select all objects, or limit the operation to specific object types or IDs. In addition to export/import endpoints, a validation endpoint is provided for troubleshooting.

      By default, system-created collections are not exported. See below for details.

      Object export and import

      Collections and encrypted values are treated specially; details are provided below. During import, conflicts are resolved according to the specified import policy.

      For objects other than collections, no implicit filtering is performed; all objects are included by default. However, on export you can filter by type and ID.

      Supported objects

      Fusion lets you export and import the object types below. To filter by type, use the values below with the type query string parameter; see the examples below.

      Object type Value Output



      The deep parameter is not needed for this object type. In the case of apps, all linked objects are included by default.

      Exporting and importing collections

      Collections are processed with these dependent objects:

      • features

      • index profiles

      • query profiles

      Datasources, parser configurations, and pipeline configurations are not included when collections are exported or imported. These must be exported and imported explicitly.

      Only user-created collections are included by default. Certain types of collections are excluded:

      • the "default" collection

      • collections whose type is not DATA

      • collections whose names start with "system_"

      • "Secondary" collections, that is, collections created by features

        Instead, create the same features on the target system; this automatically creates the corresponding secondary collections.

      You can override these exclusions by specifying a collection, like this:

      curl -u user:pass http://fusion-host:8764/api/objects/export?collection.ids=default > collection.zip

      Encrypted passwords

      Some objects, such as datasources and query pipelines, include encrypted passwords for accessing secure data.

      • On export, these encrypted values are replaced with one of the following:

        • secret.dataSources.datasourceID.password

        • secret.queryPipelines.pipelineID.stages.active-directory-security-trimming.stageID.bindPassword

      • On import, the original, plaintext passwords must be provided in a separate JSON map as multipart form data:

        Passwords can also be uploaded via the UI. Variables that do not start with secret. are ignored.

      Import policies

      On import, the importPolicy parameter is required. It specifies what to do if any object in the import list already exists on the target system:


      If there are conflicts, then import nothing.


      If there are conflicts, then skip the conflicting objects.


      If there are conflicts, then overwrite or delete/create the conflicting objects on the target system.

      Filtering on export

      On export, there are two ways to specify the objects to include:

      • by type

        To export only specific types of objects, you can specify one or more object types using the type query string parameter. See Supported objects for a list of valid values.

      • by type and ID

        The type.ids parameter lets you list the IDs to match for the specified object type.

      The type and type.ids parameters can be combined as needed.

      Exporting linked objects

      Related Fusion objects are linked. You can view linked objects using the Links API or the Object Explorer.

      When exporting a specific Fusion object, you can also export its linked objects without specifying each one individually. To export all objects linked to the specified object, include the deep="true" query parameter in your request. See the example below.


      Objects are validated before import. If any objects fail validation, the whole import request is rejected. A separate endpoint is available for validating objects without importing them.

      Validation includes checking whether an object already exists on the target system and whether the user is authorized to create or modify the object.

      For collection objects, the following special validation is performed:

      • We check the searchClusterId of each collection and verify that a cluster with this ID exists on the target system or in the import file (error).

      • We check that features, index profiles, and query profiles belong only to the collections specified in the import file (error).

      • We check that a feature exists on the target system for each feature in the import file (error).

      • We check for index profiles or query profiles that do not exist on the target system or in the import file (warning).

      Status messages

      Validation completed with no errors

      The validation method was called and no errors found, though there may be warnings.

      Validation found errors

      The validation was called and errors found. Validation does not stop on the first error, so the complete list of errors is reported.

      Validation was not completed because of system error

      The validation was interrupted by system error.

      Import was not performed because validation errors exist

      The import method was called, but import didn’t start because of validation errors.

      Import was not performed because of input data error

      The import method was called, but import didn’t start, because Fusion could not find a substitution for one of the secret values in objects in import.

      Import was not completed because of system error

      The validation found no errors and import started, but it was interrupted by system error.

      Import was completed

      Validation found no errors and import finished successfully.
