    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.

    Configuration in n8n

    1. In your n8n workflow, add a ClickSend node
    2. Click Create new credential (or select an existing one)
    3. In the credential form:
    ClickSend Username — paste your ClickSend login email
    ClickSend API Key — paste the API key from the dashboard
    4. Click Save
    5. n8n will test the credential automatically by calling GET /v3/account
