A business can provision **multiple API keys**, each scoped to a configurable set of **permissions** (e.g. read transactions, create deposits, etc). Permissions are chosen per key at creation time in the dashboard and may be revoked by deleting the key. Requests made with a key that does not include the permission required by the target endpoint will be rejected with a `403 Forbidden` response; an unrecognised, malformed or revoked key returns `401 Unauthorized`. Manage your keys and their permissions under **Developer → API keys** in the dashboard. ````
