  description: "## API idempotency \nEach `POST` request creating a resource (for example a transaction) requires to send a unique idempotency key. It is included in the `Idempotency-Key` HTTP header. Idempotency key helps prevent duplicates in your `POST` requests. We recommend using an **UUID** for the key, however you may use any other unique identifier you choose.\n\n#### Preventing duplicates \nIf we have already processed the request and you send a request using the same idempotency key, it will fail with an error, returning a ```409 Conflict``` response.\n\n## Case-sensitivity\nAll properties/keys within request's/response's payload are case-sensitive.\n\nHTTP headers' names are case-insensitive.\n\n## API base URL\n**Sandbox: [https://accounts.sandbox.volt.io]()**\n\n**Production: [https://accounts.volt.io]()**"
