I'm using this endpoint: http://developers.marketo.com/rest-api/endpoint-reference/lead-database-endpoint-reference/#!/Campaigns/scheduleCampaign… and passing tokens values as below format:
"value":"test value string"
But for every request that I send, I always get "system error 611". I'm not sure what point I'm missing at. I checked all the API user permissions and the campaigns and program tokens, but I don't know why I'm getting this error.
I will have to log a ticket to the marketo support, but was wondering if anyone else is/has faced this issue.
