Every error uses the [same envelope](https://upfour.io/docs/api/responses.md). | Status | Code | Meaning | | --- | --- | --- | | 400 | [bad_request](https://upfour.io/docs/api/errors#code-bad_request) | The request is malformed or fails validation. | | 402 | [billing_action_unavailable](https://upfour.io/docs/api/errors#code-billing_action_unavailable) | The Company's billing state does not allow this action. **When:** A metered or limited action while the billing state, such as paused or without credit, blocks it; details holds the action and billing_state. **Fix:** Top up the credit or change the plan, then retry. | | 429 | [confirmation_rate_limited](https://upfour.io/docs/api/errors#code-confirmation_rate_limited) | Subscriber confirmation emails are being sent faster than the limits allow. **When:** Adding subscribers faster than the confirmation limits allow; details.reason says which limit, and details.retry_at and Retry-After say when to try again. **Fix:** Wait until details.retry_at, then add the remaining addresses. `confirmation_rate_limited`: no further confirmation mail can go to this address right now. `error.details.reason` is `too_soon` (2 minutes between mails per page and address), `daily` (3 per 24 hours) or `open` (5 open confirmations per address); `error.details.retry_at` and the `Retry-After` header say when the same request can succeed. | | 404 | [not_found](https://upfour.io/docs/api/errors#code-not_found) | The requested resource does not exist or is outside the caller's scope. | | 403 | [permission_denied](https://upfour.io/docs/api/errors#code-permission_denied) | The credentials do not permit this action. | | 503 | [quota_gate_unavailable](https://upfour.io/docs/api/errors#code-quota_gate_unavailable) | The limit check itself failed, so the action was not carried out. **When:** The quota service could not decide while the request ran. **Fix:** Retry in a moment; nothing was changed. | | 403 / 429 | [quota_limit_reached](https://upfour.io/docs/api/errors#code-quota_limit_reached) | A usage or inventory limit of the Company was reached. **When:** Counters and concurrency limits answer 429 with Retry-After, inventory and capacity limits answer 403; details holds purpose, limit and window. **Fix:** On 429 wait Retry-After seconds; on 403 free something up, request a higher limit where details.raise_request is true, or buy an extension. | | 422 | [subscriber_confirmations_full](https://upfour.io/docs/api/errors#code-subscriber_confirmations_full) | Too many addresses are waiting for confirmation. **When:** An import or sign-up that would exceed the number of unconfirmed addresses allowed; nothing was added, details gives new_addresses and free_places. **Fix:** Wait for confirmations or remove unconfirmed addresses, then add fewer addresses. | | 402 | [subscriber_import_requires_payment](https://upfour.io/docs/api/errors#code-subscriber_import_requires_payment) | Subscriber import is locked while the Company is on its starting credit. **When:** Importing subscribers before the first payment. **Fix:** Top up the credit, then import. | | 409 | [subscriber_import_running](https://upfour.io/docs/api/errors#code-subscriber_import_running) | Another subscriber import of this Company is still running. **When:** Starting an import while a previous one has not finished. **Fix:** Wait for the running import to finish, then start the next. | | 413 | [subscriber_import_too_large](https://upfour.io/docs/api/errors#code-subscriber_import_too_large) | The subscriber file is over the size limit. **When:** Uploading a subscriber file larger than details.max_bytes. **Fix:** Split the file into smaller ones. | | 422 | [subscriber_import_too_many_rows](https://upfour.io/docs/api/errors#code-subscriber_import_too_many_rows) | The subscriber import has too many rows. **When:** An import with more rows than details.max_rows; nothing was imported. **Fix:** Split the import into several files. | Every call can also return `unauthorized` (401), `rate_limit_exceeded` (429) or `internal_error` (500 / 502).
