Before you Begin

What are Code Snippets?

Code snippets are short pieces of code you can reuse in your own applications. Please read this information carefully before attempting to use the code snippets.

Prerequisites

  1. Create a SendLime account — sign up for free.
  2. Generate an API key — your key starts with sl_live_ and is used in the Authorization header.
  3. Add balance for SMS — SMS messages cost credits. Top up from the Billing page.
  4. Connect WhatsApp for WhatsApp messages — use your default WhatsApp profile, or pass a WhatsApp brand_id to select a specific approved profile.

Authentication

All API requests require a Bearer token in the Authorization header:

Authorization: Bearer sl_live_your_key_here
