The Coveo Machine Learning API configs/{configurationType} endpoints allow you to download and upload an advanced configuration file attached to a Coveo Machine Learning (Coveo ML) model.

Ensure that you’re using an access token with Machine learning - Models - Edit privilege in the target organization (see Add an API key).

Usage overview

The following steps explain how to download a model’s existing advanced configuration file to edit its configuration, and then upload the edited file to the model. If you’re creating an advanced configuration file from scratch, you can go directly to step 2.

Step 1: Download an existing advanced configuration file

Use the GET configs/{configurationType} operation to download a model’s existing advanced configuration file.

Authenticate the request using an access token granting the Machine learning - Models - Edit privilege in the target organization (see Add an API key).

The following request retrieves a model’s desired advanced configuration file:

GET https://platform.cloud.coveo.com/rest​/organizations​/<ORGANIZATION-ID>​/machinelearning​/models​/<MODEL-ID>/configs​/<CONFIGURATION-TYPE> HTTP/1.1

Authorization: Bearer **********-****-****-****-************

For the following example, the downloaded file is a Block lists file containing a list of terms to be avoided by the model when providing suggestions.

200 OK response body

Example
knight
black knight
dark knight
sword
sabre

Step 2: Create or edit the downloaded advanced configuration file

If you downloaded an existing advanced configuration file, you can edit its configuration using your favorite text editor. You can also create it from scratch.

Step 3: Upload an advanced configuration file

When you edited the desired configuration file, use the PUT configs/{configurationType} operation to upload a model’s advanced configuration file. Note that the maximum allowed file size is 10 MB.

Authenticate the request using an access token granting the Machine learning - Models - Edit privilege in the target organization (see Add an API key).

The following request uploads a model’s desired advanced configuration file:

PUT https://platform.cloud.coveo.com/rest​/organizations​/<ORGANIZATION-ID>​/machinelearning​/models​/<MODEL-ID>/configs​/<CONFIGURATION-TYPE> HTTP/1.1

Authorization: Bearer **********-****-****-****-************

200 OK response body

{
  "modelId": "<MODEL-ID>",
  "filePath": "<FILE-PATH>"
}

Reference

Authenticating

The Advanced Model Configurations API relies on the bearer HTTP authentication scheme. All HTTP requests made to the Coveo Machine Learning service must include an Authorization header with a valid access token (that is, an API key or OAuth2 token):

Authorization: Bearer <token>

To download or upload a model’s advanced configuration file, the <token> must grant the Machine learning - Models - Edit privilege in the target organization.
