This is the endpoint used for adding recipients to a survey. It has a limitation of 1000 requests per minute which is reset every minute (at 00:00, not 60 seconds after the last request). Valid Survey id for existing survey needs to be provided.
We automatically filter out duplicate emails and prevent the same email being uploaded and sent more than once every 10 minutes.
If you need to add a large batch of recipients at once, see our documentation for Bulk API
If adding metatags by score type (e.g. thank_you_note_promoter, thank_you_note_passive, thank_you_note_detractor) they will work only if 'Customise based on score' switch is enabled within the web interface (on the design step of the survey).
For thank_you_link_url and thank_you_link_note to work, you will also need to enable the 'Add a link' switch in the web interface.
Using this endpoint, you can also include properties and metatags
