503 error occurring seemingly connected with mobile_conversion_re_engages metric

[John_Developer]

I don’t know whether this is a bug or not, but I’m experiencing a 503 error when calling the GET stats/accounts/:account_id/funding_instruments endpoint. The error only occurs for this endpoint (our application calls 12 endpoints in total), and it also only occurs for 1 of the 3 accounts we’re currently testing with. We supply a large number of metrics to this call, and following some investigation I’ve established that the inclusion of the mobile_conversion_re_engages metric is the sole cause, i.e. removing only this one from the request list causes it to works correctly, giving a 200 response.

The API call which causes the error (i.e. including mobile_conversion_re_engages) is as follows:

Please let me know if more information is required, many thanks.

It is likely that you are requesting for too much data at once by specifying many funding instruments. Since a funding instrument is one of the most expensive levels of aggregate data to request data at, we would recommend that you request only 1 at a time and only for metrics that would make sense to analyze at a high level (such as basic billing information). Please also review our Best Practices document here: https://dev.twitter.com/ads/analytics/best-practices

Thanks,
