I have 4 forms on my website which I need them to send data to a custom build CRM by a (given) PHP code. The data will be send on submit.
1. which hook should I use to able me to send data on/after submit.
2. what php code should I use to specify what fields to send.
3. how can I use a hook for each form (each form that sent to the CRM should have a different name).
