How can I delete tasks over a certain size using an APEX EXECUTE code? Basically I want to delete tasks that are larger than 4mb.

Is this something that will need to be custom made? 

Hello,

Does anyone know if it is possible to integrate WeChat with Salesforce?
Salesforce support said there is no standard plugin and we could not find any application on AppExchange.
We have contacted wechat support by mail but we did not receive any reply.

Best Regards,
Shamina
