User rate limit (403 error) with Google AdSense API - adsense

Question

When making requests to the Google AdSense API I reach the user rate limit. It occurs when three users (different gmail accounts) with access to the same AdSense account are making requests at the same time. I have made sure that one user is only allowed to make 1 request per second and checked in Fiddler that it is actually working.
In the Google API console I find these quota limits:
Queries per day = 10 000
Queries per 100 seconds per user = 100
Queries per 100 seconds = 500
Have anyone else encountered this issue? Also does anyone know if the limit Queries per 100 seconds is per application or per account? I can't find any information about it in the API documentation. I am wondering if I might have reached that limit somehow.

Yesterday, I happen to run into the same issue.
Adsense management API v1.4 responses:
//when the API presumes "Queries per 100 seconds per user" limit breached.
{
"error": {
"errors": [{
"domain": "usageLimits",
"reason": "userRateLimitExceeded",
"message": "User Rate Limit Exceeded"
}],
"code": 403,
"message": "User Rate Limit Exceeded"
}
}
//when the API presumes "Queries per 100 seconds" limit breached.
{
"error": {
"errors": [{
"domain": "usageLimits",
"reason": "rateLimitExceeded",
"message": "Rate Limit Exceeded"
}],
"code": 403,
"message": "Rate Limit Exceeded"
}
}
For google, 1+1 requests might not be counted as exactly two.
You can force produce these limit breaches by reducing your quotas on google developer console.
I advise you to fix your code so that it retries after 2-3 minutes when you hit those limits again.
