[SalesForce] Solution to manage web to lead maximum daily limit

so there are a couple of tricks you can do.

Background: you can include custom fields in your web to lead, and use css/html to hide them and or pre populate the data.

so, with that in mind, I like to do the following.

Put the form on the page, with an unpopulated, hidden field called "Web2lead__c" or some such. Strip out the OrgID from the form.

Write a javascript function that populates the form's oid and web2lead__c fields either on the dom's load completion event or on the form's submit button being clicked.

This cuts down on spam, and helps you pre-funnel things by origin.

Here's my hunch:

If we go thru the order of execution of triggers it mentions running the assignment rules after both the after and before triggers have finished running, which implies owner field will be changed again when the assignment rules fire. And here's another link which explains how the leads are assigned when it is generated from web-to-lead. It says that if the assignment rule fail to locate an owner (in your case there are no assignment rule) then the lead will be assigned to the default owner as mentioned in the setting or If you do not use assignment rules, all web leads will be assigned to the Default Lead Creator.

Setting the owner in a future method should do the trick as that will be considered another transaction.
