Install and connect the WordPress plugin

Install SplitSMS v1.7.2, paste a full API key, pick a Sender ID, and send a test.

For WordPress site owners

1. 1

   Create the SplitSMS account first

   Sign up on splitsms.com, add wallet credits, and request a Sender ID. The plugin does not send until the cloud account has an approved sender and balance.

2. 2

   Create an API key

   Open Developers → API Keys (or Dashboard → App connections). Create a key with sms.send (and sender_ids.read so the plugin can list senders). Copy the full ~56-character secret immediately — the dashboard only shows a prefix later.

3. 3

   Install the plugin

   WordPress.org: Plugins → Add New → search SplitSMS → Install → Activate. Manual: download the zip from Integrations → WordPress (v1.7.2) → Upload Plugin → Activate. If an old splitsms* folder exists, delete it first.

4. 4

   Connect and test

   In wp-admin open SplitSMS → Settings. Paste the full API key, pick the Sender ID, set an admin phone, Test connection, then Save. Send a test SMS from the plugin Dashboard. The site then appears under SplitSMS Dashboard → Integrations → WordPress.
