Hey @rasulkireev,
Thanks for sharing all the links and code about your what your setup is and what you’ve tried so far. I took a look at your site and see that you have recently received some form submissions:
So is the problem that the submissions aren’t collecting all the data you want? If that’s the issue, based on your StackOverflow post, there might be a problem with how you’re sending data to Netlify, your data encoding function (I don’t see one in the code you sent), etc. Here’s some sample code that may help you debug:
Or is that part working correctly and the problem is that EmailOctopus is not receiving the form data after it’s been submitted to Netlify? If it’s the latter, that would suggest an issue with the submission-created function. This tutorial has a good walkthrough with submission-created code:
Let us know how you go with this and if we can help further!
