What is the current rate limit for the User API?
You can send up to 50 requests per 10 seconds. If you exceed this limit, you will be blocked for the next 1 minute.
Is it possible to increase this limit?
Unfortunately, it's not possible to increase this limit.
Do you keep a history of this limit?
No, rate limits are calculated every 10 seconds and then removed from our database.
If I reach this rate limit, will that affect my end-users?
Only on the UserGuiding's server-side API a 429 error code will be thrown; so your end-users won't see such an error or be affected by it.
