Register

Self-service registration. Creates a tenant, issuer, and sandbox API key in one call. The returned API key is shown once — store it immediately.

POST /v1/register

Authentication

None — public endpoint.

Rate limiting

Shared with POST /v1/resend-verification — 5 requests per hour per IP.

Request body

multipart/form-data (required — a P12 certificate file must be included).

Field	Type	Required	Description
cert	file	Yes	P12 certificate file from SRI
certPassword	string	No	P12 password (omit if none)
email	string	Yes	Tenant contact email — used for verification and invoice notifications
ruc	string	Yes	13-digit RUC
businessName	string	Yes	Legal business name (max 300 chars)
tradeName	string	No	Trade name
mainAddress	string	No	Main address
branchCode	string	Yes	3-digit branch code, e.g. 001
issuePointCode	string	Yes	3-digit issue point code, e.g. 001
environment	string	No	(Deprecated — ignored) Historically controlled SRI environment. All new accounts start in sandbox; use POST /v1/tenants/promote to move to production.
emissionType	string	Yes	1 (normal emission)
requiredAccounting	boolean	Yes	Whether the business is required to keep accounting
specialTaxpayer	string	No	Special taxpayer code
branchAddress	string	No	Branch address
documentTypes	array	No	Document type codes to enable (default: ["01"]). Must be supported types.
initialSequentials	array	No	(Deprecated — ignored at registration) Starting sequential numbers per document type to use at promotion time. Pass these to POST /v1/tenants/promote instead.
language	string	No	Language for outgoing emails. Supported: es (default), en. Stored on the tenant and used for all subsequent emails including resends.
verificationRedirectUrl	string	No	Frontend URL where the verification link in the email will point. The token is appended as ?token=<token>. If omitted, the link goes directly to the API's verify endpoint.

verificationRedirectUrl behaviour

When set, the verification email contains a link to your frontend page:

https://app.comprobify.com/verify?token=<64-char-hex>

Your frontend page should display a confirmation UI and then call GET /v1/verify-email?token=<token> on user action.

When omitted, the link goes directly to the API:

https://api.comprobify.com/v1/verify-email?token=<64-char-hex>

Validation: in production (APP_ENV=production) the URL must use https. In staging, http is also accepted.

Response

201 Created — new registration

{
  "ok": true,
  "tenant": {
    "id": 1,
    "email": "[email protected]",
    "subscriptionTier": "FREE",
    "status": "PENDING_VERIFICATION",

    "certExpiry": "2027-01-01T00:00:00.000Z"
  },
  "apiKey": "abc123..."
}

200 OK — email already registered (key recovery)

If the email is already registered and not suspended, the current sandbox key is revoked and a fresh one is returned. Same response shape as 201 but with recovered: true.

Errors

Status	Code	When
400	VALIDATION_ERROR	Missing or invalid fields, or missing P12 file
400	BAD_REQUEST	P12 file is corrupt or the certificate password is wrong
403	FORBIDDEN	The account is suspended
409	CONFLICT	RUC already registered under a different email
429	TOO_MANY_REQUESTS	Rate limit exceeded

Notes

• The tenant starts in PENDING_VERIFICATION status. A verification email is sent immediately (fire-and-forget).
• Unverified tenants can use sandbox but cannot promote to production.
• The verification token expires after the configured TTL (default 24 hours). Use POST /v1/resend-verification to issue a fresh one.
• The endpoint is idempotent on the email address — safe to retry if the API key was lost.
