# Create tags

Create a profile tag.
- **Preconditions**: the name must be non-empty, at most 100 characters, and not already used by a tag in the team.
- **Effect**: creates the tag and returns its id. Unlike groups, tags have no count limit.
- **Retry**: a duplicate name is rejected rather than reusing the existing tag. Confirm with `/envtag/all`.
