Casa Layer · Every guest, remembered.

Generate an API key

In the Casa Layer app, open the account menu at the bottom of the sidebar and choose Account settings, then Create Key. Give the key a name and — optionally — pin it to a single property; otherwise it reads your whole property group.

The casa_… token is shown once, at creation. Copy it immediately — only a hash is stored, and it can never be retrieved again.

Make your first request

Every endpoint takes the key as a bearer token:

curl https://api.casa-layer.com/v1/guests \
  -H "Authorization: Bearer casa_your_key_here"

{
  "data": [
    {
      "id": "9b1deb4d-3b7d-4bad-9bdd-2b0d7b3dcb6d",
      "first_name": "Ada",
      "surname": "Lovelace",
      "email_address": "[email protected]",
      "tags": ["vip", "returning"]
    }
  ]
}

Drill into one property (optional)

A group-scoped key returns data across every property in your group. Add X-Property-Id to narrow a request to one property:

curl https://api.casa-layer.com/v1/reviews/summary \
  -H "Authorization: Bearer casa_your_key_here" \
  -H "X-Property-Id: 7c9e6679-7425-40de-944b-e07fc1f90ae7"

Connect an AI assistant (optional)

The same key authenticates the MCP server, so Claude, Cursor, and other MCP clients can search master profiles, reservations, reviews, and the guest event log directly.
