Error Code Help

I've been seeing error code 606 come up quite frequently. I looked up in Marketo what this error code stands for but I'm not exactly understanding how its happening. The description for it is "the number of calls in the past 20 seconds was greater than 100". Does anyone know, does this refer to maybe a list import working with marketo api to salesforce and loading in new calls into inside sales? Anyone have any idea what exactly this error code means or how I can know exactly what's happening to cause it?

Re: Error Code Help

Question should be in Products​, so if you could move it that would be great.

Salesforce API calls are not involved in this rate limit... your description of the suspected cause is hard to understand.

The rule is that integration(s) using the Marketo API cannot make more than 100 calls in 20 seconds. That's calls inbound to Marketo. 

One single-threaded app (meaning it makes only one network connection at a time, waiting for that one to complete before opening the next one) is unlikely to exceed 5 calls per second (not impossible, but unlikely).

However, a multi-threaded (or multi-process, etc.) app, or multiple apps, can overwhelm the limit if not specifically coded to stay within limits.  For example, an app that has 5 threads connecting to Marketo independently, without coordinating with each other, means you only need to complete 1 connection per second per thread to break the rules.

So I don't know what integrations you're writing/using, but a seemingly "robust" one may be the culprit, since aiming for higher performance without specific attention to rate limits can end up causing this error.  You also might look for apps that get launched by some kind of scheduler many times simultaneously (in this case, the individual app is innocent, but somebody decided to try to increase throughput by launching many times).

Re: Error Code Help

so this would have nothing to do with list import and calls being loaded into inside sales?

Re: Error Code Help

Not if that list import is hitting the Salesforce API.  When you import into SFDC, you use their API calls.  Then Marketo will use other SFDC API calls to do the SFDC sync. The Mkto API is not used in these processes.

Re: Error Code Help

I upload the list into marketo so I would think it's using Marketo API, no?

Re: Error Code Help

If you upload via the UI, you aren't using the API. If you have a custom app that uses the import API, then yes, you're using the Marketo API. It would be a pretty strange app if when doing bulk (?) imports it so drastically parallelizes that it overwhelms the API limits. That ain't right! But if I don't have the source code. I can't say.

Bonnie Seaman​ Have you reviewed what connections you have making API calls? You can do this in Admin > Web Services > click on the number next to requests last 7 days. This might give you an indication of what your robust API connection is.
