A developer experience survey asks the people building on your API how the first steps went. This template asks four questions in about a minute: how easy it was to make the first successful API call, which language they use most, a ranking of what helped, and where they got stuck, even briefly.
It is written for an email to developers a few days after they create their first API key, sent each week to the developers with new keys. The same survey works as a link at the end of your quickstart guide, and inside the page on your developer docs when they run on your own domain.
Results shows the average effort on the 1 to 7 scale and the share who found it easy, the share of each language and the average place of each resource in the ranking. Every written answer is read as it arrives and filed under a category such as getting started or integrations, with a theme and a type, so a confusing error and a missing SDK come apart.
