    Fusion REST APIs

    Fusion’s REST APIs provide programmatic access to Fusion services and features. You can use the APIs to automate tasks, integrate Fusion with other systems, and build custom applications.

    API authentication

    There are two ways to authenticate when making API calls to Fusion:

    • Basic authentication with a username and password

    • API key authentication

    Authenticate with basic auth

    You can use a Fusion username and password to authenticate with Fusion’s REST API. The user’s role and permissions must include access to the endpoints and methods you want to use.

    Authenticate with an API key

    You can use an API key instead of a username and password combination to power your search application or operations. Pass your API key to Fusion using either apiKey or x-api-key, as in these examples:

    curl -H "x-api-key: API_KEY" "https://FUSION_HOST/api/query/status"
curl -H "apiKey: API_KEY" "https://FUSION_HOST/api/query/status"

    For more information, see API Keys.

    Access API endpoints

    API endpoints follow this pattern:

    https://FUSION_HOST/api/SERVICE_NAME/ENDPOINT

    Example: https://FUSION_HOST/api/query/query-pipelines

    Discover API endpoints

    There are several ways to discover Fusion’s REST API endpoints.

    Discover endpoints in the docs

    Navigate this documentation to find the API for each Fusion service. On any API documentation page, click the View API specification button to see the Swagger/OpenAPI specs for that service’s API endpoints.

    You can also jump directly to the specs from here:

    Access the Swagger UI

    To enable Swagger, use --set swagger.enabled=true in the Helm chart install command.

    Authentication and authorization rules do not include the Swagger user interface; anyone with network access to your Fusion instance can see it. Before enabling Swagger, determine your organization’s security requirements.

    Access the Swagger UI at this URL:

    https://FUSION_HOST/swagger-ui/index.html

    Use the Explore bar to switch between the APIs for different services. For any API you want to see, enter /SERVICE_NAME/v3/api-docs in the Explore bar. For example, enter /indexing/v3/api-docs to see the Indexing API:

    Get the API specs in JSON

    You can view or download the JSON-formatted API specs for each service by appending /v3/api-docs to the service’s base URL:
