To use any of the above modules, you need to connect your SendinBlue account to Integromat. If you do not have a SendinBlue account yet, you can create one at sendinblue.com.
To connect your SendinBlue account to Integromat, follow the general instructions for Connecting to services.
After clicking on the Add button, another window will open which will require you to type an API key. To get the API key, log into your SendinBlue account and in the top right corner, click on your profile icon and select SMTP & API.
Copy the displayed key and paste it into the API key field in Integromat. After that click on the Save button.
Next, select the Event type and Events you want to be notified of, and click on the Save button once again.
This will create a webhook which will allow Integromat to receive a notification when a specified event occurs in SendinBlue. The URL address that Integromat listens to for the event will be automatically registered with SendinBlue, you don't have to enter it manually.
Now you can continue and finish your scenario.
