    3. Click **ADD CUSTOMER**.
    4. Under **Customer information**, enter the following details:
       * **Customer name:** `ACME Inc.`
       * **External ID (optional):** Any ID associated with `ACME Inc.` in your CRM or CIS or similar system.

    -H 'Content-Type: application/json' \
    -H 'x-api-key: <your-api-key>' \
    -d '{
