Unit API: JSON:API error format and sandbox base URL

Export

Unit API: JSON:API error format and sandbox base URL: : the Unit API is built on the JSON:API specification with media type application/vnd.api+json, secured with Bearer or JWT tokens, and the sandbox base URL is https://api.s.unit.sh.

[unit.co docs via api-evangelist/unit-co]: the Unit API is built on the JSON:API specification with media type application/vnd.api+json, secured with Bearer or JWT tokens, and the sandbox base URL is https://api.s.unit.sh. Point sandbox credentials at the sandbox host: calling production with a sandbox key, or the reverse, fails auth with no useful message. A single REST API covers Applications (onboarding), Customers, deposit accounts, cards, and payments, so one error-handling shape covers every resource.

Context: Two integration basics that break first-time Unit integrations: the error envelope shape and the sandbox host.
