Copy for LLM[View as Markdown](</articles/api-reference/Technical questions/how-to-create-short-links-with-prefixes.md>)

**Short.io** allows you to create via the API functionalities short links with **prefixes** (or **static values**) in the following format:

**`<Your-domain>` / `<Static-value>` / `<Slug>`**

**For example**, *mydomain.io/XmasCampaign/SomeShortLink.*

To effectively accomplish the task, follow the detailed instructions below.
