How to Generate API Key
Before you can send your first email, you need to generate your API Key. Open the Configuration > API Key menu then click Create API Key button.
In Create API Key menu, user should fill API Key Name, assign API key into subaccount that created before, and choose API permission, then click Create API Key button to finish the process.
IMPORTANT: You can only generate the API key once, copy and store the API key safely because you won’t be able to see it again.
