Error codes and message guide

Clear explanations and helpful next steps for every published fylt response code.

How to read a fylt message code

Every message fylt shows you carries a short code so that the same situation is always described the same way, whether you hit it in the app, in an email notification, or through the API. Codes are grouped by the kind of problem they describe, which usually tells you who can fix it and how quickly.

Account and access messages mean the action was understood but you are not currently permitted to perform it — usually a role or permission question for your workspace owner or admin, not a fault.
Validation messages mean something in what was submitted needs correcting, such as a missing required field, a date in the past, or an amount that does not match its currency. These are always resolvable by you, and the message names the specific field.
Workflow messages mean the action conflicts with the current state of a record — for example trying to send a document that is still awaiting approval, or invoicing a project that has already been closed. The resolution is to move the record to the right state first.
Rate and quota messages mean too many requests arrived too quickly, or a plan limit has been reached. Waiting briefly resolves the first; the second is resolved from your subscription and billing settings.
Service messages mean something failed on our side. These are the only category you cannot resolve yourself, and they are worth reporting.

Before contacting support

Most reports are resolved faster when they include three things: the exact code shown, what you were trying to do immediately beforehand, and the approximate time it happened. If the message relates to a specific record, the record’s reference is helpful too. You can raise this from within your workspace, and it arrives with your account context already attached.

For setup and configuration questions rather than errors, start with the knowledge base or the onboarding guide. For account protection and sign-in questions specifically, see account security.
