Modify the JSON in CF7

Hi there,

Thanks for a great plugin, working really well.

I want to use the same webhook from multiple similar CF7 forms and then use a router in Integromat to direct the content accordingly.

In order to do this I need an extra field which contains a specific code for each CF7 form. This field can’t be a form field as such.

Would be possible to either give us write access to the JSON and we can update it manually or add an extra field in the intergration section or add the CF7 form slug to the JSON or any other way that will fit this prupose?
Thanks,
Phil
