Tracking Survey Monkey responses in Rails

Question

I am building a rails application that requires users to take a survey on Survey Monkey. How can I reliably correlate a user of my app to their Survey Monkey response, which I am pulling using the Survey Monkey API? Matching IP would work some of the time, but its not very reliable.

Thanks!

Answer 1

Use the 'custom id' (aka 'custom value') when sending the survey:

You can also do this with email collectors as long as you fill out the recipient correct and populate its custom value.

Then when you call get_respondent_list ask for 'custom_id' as one of the fields, this will be populated with the value you provided.
