# Docsumo API auth: X-API-KEY header, not Authorization Bearer

## TL;DR

Send the key as the X-API-KEY header; an Authorization Bearer header will not authenticate you. Grab the API key from Settings, Webhook and API, API Key. Capture doc_id from every upload response; the analytics endpoints are keyed on those IDs.

Use this when you run into the situation in the title.

**When not to use this skill:** unrelated tasks. It covers only the procedure above.

## Compatibility

The steps above apply to the commands named in them. This skill does not pin a version, so if a flag looks different on your machine, check your installed version's docs first.

## Details

Context: Official docs (Docsumo account summaries API): documents that API calls authenticate with an X-API-KEY header (API key from Settings > Webhook and API > API Key), and that analytics endpoints consume doc_id values returned when documents are uploaded.
