Messenger error 10: Page restricted from opt-in requests

Code 10 with subcode 1404170 returns the generic string "Application does not have permission for this action," but Meta's error-codes table pins the actual meaning: it fires "when the Page is temporarily restricted from sending Marketing Message opt-in requests." The Page asked too many people, or the wrong people, too often, for permission to send recurring marketing notifications, and the platform has paused the Page's ability to ask.

The marketing-messages system is consent-driven, and Meta polices the consent-gathering step as firmly as the sending step. Related controls surround this one: 10/1893015 when a person has stopped a topic, the documented code 9/2018352 family when the opt-in request limit per user is exceeded, and the legacy 613/1893016 rule against repeated opt-in requests on the same topic. Subcode 1404170 is the Page-level consequence when the pattern persists: not one user's refusal, but a restriction on the Page's opt-in machinery itself.

The restriction is temporary, with no duration in the error. While it lasts, opt-in request sends fail, but existing opted-in audiences and normal conversation are unaffected, another error best handled per-feature rather than globally. The signal to act on is behavioral: your opt-in prompting is too aggressive for your audience, and resuming the same pattern after the restriction lifts invites a longer one, on the same ladder that ends at 368.

Ask for marketing consent the way a good salesperson would: rarely, at the right moment, and never twice in a row. Encode per-user prompt budgets and engagement preconditions, and measure accept rates, a low one predicts this restriction. The marketing-messages rules sit with the other volume controls in the Messenger limits reference, and the consent-system errors are cross-linked from 10/1893015.
