Authenticate Meow API requests with x-api-key headers

API Key Authentication

The Meow API uses API key authentication. Include your API key in the x-api-key header with every request.

curl -H "x-api-key: YOUR_API_KEY" https://api.meow.com/v1/accounts

Obtaining an API Key

You can create and manage API keys from the Meow Dashboard.

Scopes

Each API key carries a set of scopes, and every endpoint requires the scope listed on its reference page. Choose the scopes a key needs when you create it in the dashboard; a request with a key that lacks the endpoint’s scope is rejected.

`accounts:write`	Create and update accounts

Multi-Entity Access

For API keys with access to multiple entities, include the x-entity-id header to scope requests to a specific entity:

curl -H "x-api-key: YOUR_API_KEY" \
     -H "x-entity-id: YOUR_ENTITY_ID" \
     https://api.meow.com/v1/accounts

Use the /api-keys/accessible-entities endpoint to list all entities accessible by your API key.
