SOAP API failing sometimes but work most of the time

[Anonymous]

Has anyone experienced SOAP API issues implementing 3rd party systems, such as ReachForce?  On a form containing ReachForce javascript that submits new leads to Marketo via the SOAP API  most leads are being passed to Marketo but for some reason not all leads are getting created in Marketo.  

Have you experienced a similar issue?  What ended up being the problem and how did you fix it?

Thanks

I was noticing a Lead not found error when looking records up by _mkto_trk sometimes.  I just added a check on a error 20103 to try a second time and I don't see and problems anymore.

The API calls are handled by backend servers that also perform other functions.  You will occassionally run into situations where there is no capacity to handle the incoming calls - because we are handling higher priority items that cannot be dropped, like form fill outs.  As a best practice, you should always try your calls multiple times when the call times out

Thanks for the response Raj.  Regarding high priority items, this is actually happening on form fill outs but on non-Marketo hosted pages so we are actually missing leads that are simply never created in Marketo.  It was only caught because it is also submitting records to an internal system which is not failing.

Jack,
I meant Marketo form fillouts have higher priority than SOAP.  We have no way of knowing that your SOAP calls are actually form fills, so you will have to retry on failure.
