Application Programming Interface (API) is a method of extracting raw Semrush data without having to manually log into the software.
Once you get your API key, you can start integrating with Semrush API.
Below you will find information about:
Two Semrush API versions are available: version 3 and version 4.
The main difference between versions is the authorization method, availability of major changes inside the feature APIs, and list of available feature reports.
Each version consists of product groups, products themselves, and product reports.
