Another popular contact form provider is MachForm, and they've linked with the Light Blue API. As with our ProPhoto and Gravity Forms plugins, you don't need to write any special code yourself.
You'll need to be using MachForm.
There's nothing special you need to do!
There are full instructions on how to connect your MachForm form on their website.
You can find a list of the parameters that the Light Blue API recognises in the Supported Parameters section. Any fields in your forms that do not have their 'value' set, or have a 'value' that doesn't match a valid Light Blue API paramater, will be ignored but processed by MachForm as usual.
The next few sections of this documentation aren't relevant to using the Light Blue API with MachForm, so you can skip ahead to the list of data types and parameters supported by the Light Blue API.
