# Workspaces and spaces

Simplified is multi-tenant on two levels. A **workspace** is the billing and membership
boundary. A **space** is a team area inside a workspace, used to separate clients,
brands, or projects.

## Scoping with an API key

An API key already carries its workspace, so most integrations send nothing extra:

```bash
curl https://api.simplified.com/api/v1/pm/boards \
  -H "Authorization: Api-Key $SIMPLIFIED_API_KEY"
```

To target a space with a workspace-scoped key, add the `Space` header:

```bash
curl https://api.simplified.com/api/v1/pm/boards \
  -H "Authorization: Api-Key $SIMPLIFIED_API_KEY" \
  -H "Space: 4821"
```

## Discovering what you can reach

```bash
# the workspace behind the current credential
curl https://api.simplified.com/api/v1/workspaces/current \
  -H "Authorization: Api-Key $SIMPLIFIED_API_KEY"

# spaces you are a member of
curl https://api.simplified.com/api/v1/spaces/my \
  -H "Authorization: Api-Key $SIMPLIFIED_API_KEY"
```

Resources are filtered to the resolved workspace and space automatically. A resource
belonging to another workspace returns `404`, not `403` — existence is not disclosed
across tenants.
