How to figure out where all of my API requests are coming from?

[sweetsummerschi]

Hi, 

I'm using a 3rd-party service called stitchdata.com to get my Analytics 360 data into BigQuery. Recently, we've been getting a lot of errors stating that the number of API requests per day are being exceeded. Before requesting to increase quota, I'd like to understand where all of my API requests are coming from and the amount of API that I use daily, since it does not make sense if it's just from Stitch. 

If anyone has any suggestions not related to my question, you're welcome as well.

The errors are like below:

HTTP-error-code: 429, Error: {'code': 429, 'message': "Quota exceeded for quota metric 'Requests' and limit 'Requests per day' of service 'analyticsreporting.googleapis.com' for consumer 'project_number:1234'.", 'status': 'RESOURCE_EXHAUSTED', 'details': [{'@type': 'type.googleapis.com/google.rpc.ErrorInfo', 'reason': 'RATE_LIMIT_EXCEEDED', 'domain': 'googleapis.com', 'metadata': {'quota_location': 'global', 'service': 'analyticsreporting.googleapis.com', 'quota_limit_value': '1000000', 'quota_metric': 'analyticsreporting.googleapis.com/analytics_default_requests', 'consumer': 'projects/1234', 'quota_limit': 'AnalyticsDefaultRequestsPerDayPerProject'}}, {'@type': 'type.googleapis.com/google.rpc.Help', 'links': [{'description': 'Request a higher quota limit.', 'url': 'https://cloud.google.com/docs/quota#requesting_higher_quota'}]}]}, Message: API rate limit exceeded, please retry after some time.
