Create links via the API

Issue tracking links programmatically with one POST request.

1. 1
   Authenticate with your API key.

   Send it as a bearer token: Authorization: Bearer YOUR_API_KEY.
2. 2
   POST /v1/links with the end-user ID and merchant UUID in the JSON body.

   fetch('https://api.capitis.app/v1/links', { method: 'POST', headers: { Authorization: 'Bearer YOUR_API_KEY', 'Content-Type': 'application/json' }, body: JSON.stringify({ end_user: 'user_42', merchant_id: '<merchant uuid from GET /v1/merchants>', campaign: 'summer25' }) })
3. 3
   The response contains the tracking URL and its token.

   Publish the URL; store the token if you want to look the link up later or tie clicks back to your own records.
