x-error-codes:
bad_request:
http_status: 400
summary: The request contained invalid or malformed parameters.
cause: A parameter failed validation, or the request body was malformed.
remediation: Inspect error_msg and error_path, correct the offending parameter, and resend.
retryable: 'no'
unauthorized:
http_status: 401
summary: The credentials supplied are missing or invalid.
cause: Missing, malformed, or invalid API key or OAuth access token.
remediation: Verify the API key or OAuth token and the Authorization header, then retry.
retryable: 'no'
payment_required:
http_status: 402
summary: The account must be credited or upgraded to perform this action.
cause: The action requires a paid plan, additional quota, or API credits.
remediation: Upgrade the plan or add the required credits/quota, then retry.
retryable: 'no'
forbidden:
http_status: 403
summary: The action is not allowed for these credentials or in the current context.
cause: The authenticated account lacks access to the resource or operation.
remediation: Confirm the account has access to the resource and the required permissions.
retryable: 'no'
not_found:
http_status: 404
summary: Nothing matches the requested resource.
cause: The resource id does not exist or is not visible to this account.
remediation: Verify the id and that the resource belongs to the authenticated account.
retryable: 'no'
conflict:
http_status: 409
summary: The request was well-formed but conflicts with the current state.
cause: The target resource is in a state incompatible with the request (e.g. a signature request is still being set up).
remediation: Wait briefly and retry, or listen for a callback event confirming the resource is ready.
retryable: conditional
exceeded_rate:
http_status: 429
summary: Your account's API request rate limit has been exceeded.
cause: Too many requests were sent within the rate-limit window for this request type.
remediation: Pace requests using the X-RateLimit-* response headers and retry after the window resets.
retryable: 'yes'
backoff: Honor X-Ratelimit-Reset (Unix epoch); otherwise exponential backoff with jitter. No Retry-After header is sent.
unknown:
http_status: 500
summary: An unexpected error occurred.
cause: An unhandled server-side error, or a status code without a more specific error_name.
remediation: Retry transient failures; if it persists, contact support with the request details.
retryable: conditional
backoff: For transient 5xx, retry with exponential backoff; otherwise do not retry.
team_invite_failed:
http_status: 403
summary: The team invitation could not be completed.
cause: The invitee already belongs to a team, or the invite is otherwise not permitted.
remediation: Confirm the invitee is not already on a team before inviting.
retryable: 'no'
max_faxes:
http_status: 429
summary: Too many fax transmissions are currently pending or transmitting.
cause: The account has reached the limit of concurrent in-flight fax transmissions.
remediation: Wait for outstanding transmissions to complete, then retry.
retryable: 'yes'
backoff: Retry with exponential backoff once pending transmissions clear.
invalid_recipient:
http_status: 400
summary: The recipient (fax number or email address) is invalid.
cause: A recipient value did not pass validation.
remediation: Correct the recipient value and resend.
retryable: 'no'
signature_request_cancel_failed:
http_status: 400
summary: The signature request could not be cancelled.
cause: The caller is not the requester, or the request is already fully executed/closed.
remediation: Only the requester can cancel, and only before the request is fully executed.
retryable: 'no'
signature_request_remove_failed:
http_status: 400
summary: Access to the signature request could not be removed.
cause: The signature request has not yet been fully executed, so access cannot be revoked.
remediation: Wait until all parties have signed, or call /signature_request/cancel to cancel incomplete requests instead.
retryable: 'no'
maintenance:
http_status: 503
summary: The request could not be completed because the site is under maintenance.
cause: The API is in a scheduled maintenance window.
remediation: Retry once the maintenance window ends.
retryable: 'yes'
backoff: Retry later with exponential backoff.
method_not_supported:
http_status: 405
summary: The HTTP method is not supported for this endpoint.
cause: The request used a verb the endpoint does not accept.
remediation: Use the HTTP method documented for the endpoint.
retryable: 'no'
invalid_reminder:
http_status: 400
summary: The signature request reminder was invalid.
cause: A reminder was attempted against an ineligible request (e.g. embedded, closed, or expired).
remediation: Only send reminders for eligible (non-embedded, open) signature requests.
retryable: 'no'
unavailable:
http_status: 503
summary: The service is temporarily unavailable.
cause: A downstream dependency or the service itself is temporarily unavailable.
remediation: Retry later with exponential backoff.
retryable: 'yes'
backoff: Retry later with exponential backoff and jitter.
unprocessable_entity:
http_status: 422
summary: The request was understood but the target entity cannot be processed.
cause: The resource is still being processed, or it is in an error state.
remediation: If the resource is still processing, wait and retry; if it is in an error state, recreate/resend it instead of retrying.
retryable: conditional
backoff: If still processing, retry with exponential backoff; if in an error state, do not retry.
signature_request_expired:
http_status:
- 400
- 403
summary: The signature request has expired.
cause: The operation targets a request whose expiration has passed. Most endpoints return 400; final-copy/download endpoints return 403.
remediation: The request can no longer be acted upon; create a new signature request.
retryable: 'no'
deleted:
http_status: 410
summary: The request was cancelled or deleted.
cause: The resource has been cancelled or removed and is no longer available.

unauthorized_client:
http_status:
- 401
- 403
summary: The OAuth client is not authorized to perform this action.
cause: The app has not been approved, or the action is outside the granted scopes.
remediation: Ensure the app is approved and the required scopes are granted.
retryable: 'no'
unsupported_grant_type:
http_status: 400
summary: The grant type is not supported.
