Getting started with the API

SplashSend has a REST API that lets you manage contacts, trigger sends, and integrate with your own systems.

Getting your API key

  1. Go to Setup in your dashboard
  2. Find the API section
  3. Generate a new API key
  4. Copy it and store it securely — you won’t be able to see it again

Authentication

Include your API key as a Bearer token in the Authorization header of every request:

Authorization: Bearer sk_live_your_api_key_here

Common endpoints

  • GET /api/v1/contacts — List your contacts
  • POST /api/v1/contacts — Create a new contact
  • PUT /api/v1/contacts/:id — Update a contact
  • DELETE /api/v1/contacts/:id — Delete a contact
