The new entity’s isolated ledger id and gapless invoice-number sequence are allocated automatically — you never manage either directly.

Request body

Parameter	Type	Required	Description
`name`	string	Yes	Display name, e.g. `"ACME US"`.
`legal_name`	string	No	Registered legal name.
`invoice_prefix`	string	No	Prefix for this entity’s invoice series; defaults to a slug of the name.
`country_code`	string	No	ISO 3166-1 alpha-2. `country` is accepted as an alias; `country_code` wins if both are sent.

Example request

curl -X POST https://api.recurso.dev/v1/entities \
  -H "Authorization: Bearer $API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "ACME US",
    "legal_name": "ACME Inc.",
    "invoice_prefix": "ACME-US",
    "country_code": "US"
  }'

Example response

{
  "data": {
    "id": "e1a7c3f9-8b2d-4e6a-9f0c-3d5b7a1e8c42",
    "tenant_id": "7d3e9a12-5b8c-4f6a-9e2d-1c7b4a8f0e35",
    "name": "ACME US",
    "legal_name": "ACME Inc.",
    "is_primary": false,
    "tb_ledger_id": 2,
    "invoice_prefix": "ACME-US",
    "country_code": "US",
    "created_at": "2026-08-12T10:00:00Z",
    "updated_at": "2026-08-12T10:00:00Z"
  }
}

Returns 201 on success. Resources created afterwards with this entity’s entity_id post to its ledger and draw from its invoice series; resources with a NULL/omitted entity_id stay on the primary entity.
