chk_stg_. Call the same /v1/* endpoints or /mcp with this key.
livemode: true and is_staging: true. Every staging call uses the shared live credit balance. Sandbox keys (chk_test_) use fixtures and separate test credits.
Select Live in the dashboard, then choose Production, Staging or All on the overview, jobs and usage screens. The live balance is shared; the consumption shown follows your filter. Usage aggregates refresh hourly.
Credentials and retries
Use a separate staging key for your staging integration. Rotation preserves its environment. The environment comes from the key; a request body or header cannot override it. The sameIdempotency-Key can be used independently in production, staging and sandbox. Retries within each environment return that environment’s original job.
Receive staging events
Create a webhook destination with Staging selected. It receives only staging job events. Production destinations receive only production events. Events carry bothlivemode and is_staging, including synthetic events sent with Send test. With no staging destination, retrieve results by polling.
