Upload content to the assistant

You can upload files to the assistant using the API. These files are available when you chat with the assistant . For information about uploading files within the assistant, see Upload and chat about files .

To upload content to the assistant using the API, run the following curl command:

  curl -X POST \ 
 -H "Authorization: Bearer $(gcloud auth print-access-token)" \ 
 -H "Content-Type: application/json" \ 
 -H "X-Goog-User-Project: PROJECT_ID 
" \ 
 "https://discoveryengine.googleapis.com/v1alpha/projects/ PROJECT_ID 
/locations/global/collections/default_collection/engines/ APP_ID 
/sessions/ SESSION_ID 
:addContextFile" \ 
 -d '{ 
 "name": "projects/ PROJECT_ID 
/locations/global/collections/default_collection/engines/ APP_ID 
/sessions/ SESSION_ID 
", 
 "fileName": " FILE_NAME 
", 
 "mimeType": " MIME_TYPE 
", 
 "fileContents": " BASE64_ENCODED_FILE 
", 
 }'

Replace the following:

PROJECT_ID : the ID of your Google Cloud project.
APP_ID : the ID of the app.
SESSION_ID : the ID of the session. You can obtain this ID from the response of creating a session, as shown in Store session information and get responses .
FILE_NAME : the name of the file.
MIME_TYPE : the MIME type of the file.
BASE64_ENCODED_FILE : the base64 representation (ASCII string) of your data. This string should look similar to the following string: /9j/4QAYRXhpZgAA...9tAVx/zDQDlGxn//2Q==

Example command and response:

  curl -X POST \ 
 -H "Authorization: Bearer $(gcloud auth print-access-token)" \ 
 -H "Content-Type: application/json" \ 
 -H "X-Goog-User-Project: 1234" \ 
 "https://discoveryengine.googleapis.com/v1alpha/projects/1234/locations/global/collections/default_collection/engines/myapp/sessions/16002628354770206943:addContextFile" \
