What is a Rate Limit?

Limits protect the service from being overwhelmed and keep one heavy user from degrading everyone else. Social platforms are especially strict: publishing endpoints often have per-account quotas on top of general request limits, because mass automated posting is exactly what spam looks like.

A 429 is not an error to panic about; it is an instruction to slow down. Well-behaved clients wait and retry with increasing delays (called backoff) and read the response headers that say when the window resets. When you build on a publishing API, check your quota before you need it: InvisibleAPI exposes live usage limits through the API, with a quota of 100 published posts per connected account per billing period.

Being rate limited means the API has stopped accepting your requests for now, because you sent too many inside its time window. Nothing is broken and nothing is banned: the requests work again when the window resets. The same message appears in apps and websites when you retry an action too quickly.

Stop sending, wait, then retry with a growing delay. Read the headers the API returns about usage or reset time instead of guessing, and spread batch jobs out rather than sending them at once. If you hit the limit every day, the fix is fewer calls: cache what you read, and check your remaining allowance before a big batch.

Instagram has two kinds of limit at once. Meta's rate limit for the Instagram Platform is 4,800 calls per impression in a 24-hour window, and publishing has its own cap of 100 API-published posts per account in 24 hours. Different limits come back as different error codes, which the Instagram API error codes guide maps to a retry decision. The Instagram posting API adds a third, separate count: its limits endpoint reports each account's remaining InvisibleAPI allowance for the billing period. It does not track Meta's rolling 24-hour cap, so a batch still has to respect both.
