Authentication

Authentication tokens (API Keys) are accepted by our GraphQL API in one of two ways.

  1. Provide as an authorization header [RECOMMENDED]:
# Pass API key as a header to make a graphql query
curl 'https://api.labelbox.com/graphql' \
   -H 'Authorization: Bearer <API_KEY_HERE>' \
   -H 'content-type: application/json' \
   -d '{"query":"[QUERY HERE]"'

# Pass API key as a header to request a mask for an annotated object
curl 'https://api.labelbox.com/masks/feature/:id' \
   -H 'Authorization: Bearer <API_KEY_HERE>'
  1. Provide as a query parameter. We do not recommend sending API keys as a query parameter for GraphQL queries.
# Passing API key as a query parameter to request a mask for an annotated object
curl 'https://api.labelbox.com/masks/feature/:

Rate limiting

The API rate limit is 500 API calls per minute per user.

When exporting labels, Labelbox will generate a new URL to the JSON payload with the most updated label information at a max frequency of 30 minutes.
