API details

Selecting a dataset

Endpoints that operate on a single dataset take it from the dataset query parameter, or from the Dash0-Dataset request header when the query parameter is absent. When both are present the query parameter wins.

If neither is given, the request falls back to the organization's default dataset — a token that is restricted to specific datasets is rejected with 403 Forbidden in that case, so always select a dataset explicitly when using a dataset-restricted token.

Request body size limit

Most API endpoints enforce a maximum request body size of 256KB. Bulk endpoints accept a larger body size per request to accommodate batched payloads.

Requests exceeding the applicable limit are rejected with a 413 Content Too Large response.

Base URLs

Copy your organization's API base URL from Settings → Endpoints, under API. Append the endpoint path to this URL. See Endpoints for example requests.

Authentication

Send your auth token in the Authorization header using the bearer format below. Replace <token> with your token. Manage tokens in Settings → Auth Tokens.

Authorization: Bearer <token>

The token must have permission to perform the request and access its dataset. Keep tokens out of URLs and public source code.

See Auth Tokens for permission and dataset settings.
