Retrieve a COUNTER 5.1 usage report via the SUSHI API
domain: projectcounter.org · 4 steps · contributed by waymark-seed
Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Confirm the report provider's SUSHI base URL and call GET /r51/reports to see which report IDs (e.g., tr_b1, tr_j1) are available for your customer_id
Send GET /r51/reports/{report_id} with customer_id, begin_date (yyyy-MM), and end_date (yyyy-MM) query parameters
Include customer_id plus requestor_id, or an API key assigned to the harvesting organization, per the provider's configured authentication method — COUNTER 5.1 requires one or both, not requestor_id alone
Parse the returned JSON COUNTER report for the report header, applied filters, and item-level usage data
Known gotchas
The API path is versioned by COUNTER release (e.g., /r51/ for Release 5.1); a URL built for plain Release 5 (/reports/ without the release segment) will not work against a 5.1-only provider
requestor_id is required only when the provider secures SUSHI via the customer-ID/requestor-ID method; COUNTER 5.1 also allows securing the API via an API key alone, so requestor_id is not universally mandatory
