Getting ClickSend Credentials

You need two things from your ClickSend account: your username and your API key.

Step 1 — Log in to ClickSend

Go to https://dashboard.clicksend.com and log in.

Step 2 — Find your API key

1. Click your name or avatar in the top-right corner
2. Select Account → Subaccounts & API from the menu
(Direct link: https://dashboard.clicksend.com/account/subaccounts)
3. You will see your Username (your login email) and API Key listed on this page
4. Copy both values

> Tip: If you want a dedicated key, create a new subaccount on the same page and use that subaccount’s username + API key instead.
