How leading teams simplify API docs
with Document360
Developers know exactly what they expect to find in API documentation, and there are firmly entrenched design elements that guide developers intuitively through an API reference. Document360 allowed us to bring our API documentation fully in line with industry standards, both meeting and exceeding our users’ expectations.
Dave Ingram
Senior Technical Writer, Mindful
We have been using Document360 for only a short while now but are super content with its features and are very excited to explore it further. We have built a self-service knowledge base site such that their customers can look for information and are able to assist themselves. This helps us to reduce the number of customer support tickets being raised.
