How to post more than 300 leads for update leads - sync api call

Question asked by Akhilesh Singh on Feb 5, 2018

Hi All,


We are in unavoidable need to update multiple leads in single api call via C# code. Api which we are calling is sync lead api, url below:


When we tried to do that we learnt that we can't update more than 300 leads in one api call, as we got below response:

{"requestId":"8167#161655d6b21","success":false,"errors":[{"code":"1003","message":"Number of leads exceeded max size 300"}]}


So could you anyone please share how to increase this limit of 300 records for batch updates?

And If it can be increased then please share what is process for same and what is maximum number to which it can be increased?

But If its not possible to increase this limit, then is there any other way/api by which we can update more records in marketo via api calls.


Thanks in advance...
