Environments

Sandbox and production are separate environments with different credentials, companies, content, and webhook registrations. Sandbox is for developing and testing your system: its companies and content are fictional, and nothing you do there affects a real company. Use it to get authentication working, to receive and verify webhooks, and to exercise fetching content and reading its files. Production is where the real Kivra Business accounts are, with its own credentials and webhook registration, so nothing from sandbox carries over.

Environment	Base URL
Sandbox	https://sender.sandbox-api.kivra.com
Production	https://sender.api.kivra.com

For example, the content endpoint is /v3/partner/company/{companyKey}/content/{contentKey}, so a sandbox request uses:

https://sender.sandbox-api.kivra.com/v3/partner/company/{companyKey}/content/{contentKey}
