Sandbox only: send it to https://api-staging.joulo.nl (pick the Sandbox server). The sandbox sends no mail. It keeps every mail to your customers, newest first, with the links in it.
Partner API key, sent as Authorization: Bearer <key>. Production keys start with jpk_live_ and work only on https://api.joulo.nl. Sandbox keys start with jpk_test_ and work only on https://api-staging.joulo.nl. Sandbox keys minted before September 2026 also start with jpk_live_. A key used on the wrong host returns 401 with a detail. A key is bound to one partner and reaches only the Partner API routes. Any other route returns 404 when it does not exist. A route that needs a scope the key lacks, such as GET /sessions, returns 403 with error: Insufficient scope and a required_scope. Every other route returns 403 with error: partner_api_key_scope. Mint and revoke keys in the partner portal. A partner has one active key at a time.
