Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Generate an API key from the target eLabFTW instance's user Settings page, choosing an appropriate access level
POST to <instance-url>/api/v2/experiments with the Authorization header set to the API key to create a new (blank) experiment
Read the Location header of the 201 response to obtain the URL/ID of the newly created experiment
PATCH <instance-url>/api/v2/experiments/<id> with attributes such as title, body (main text), category, tags, and content_type (1=HTML, 2=Markdown) to populate it
Set canread/canwrite permission JSON on the entry if it needs non-default sharing/visibility
GET the experiment back to confirm the recorded content and metadata
Known gotchas
eLabFTW is typically self-hosted, so the API base URL is specific to each institution's instance — there is no single shared public host
Creation and content population are two separate calls (POST to create a blank entry, then PATCH to fill it in), not a single combined create-with-content request
content_type must match the actual body format supplied (1 for HTML, 2 for Markdown) — mismatches can cause the body to render incorrectly in the UI
