To use Cisco Meraki integration in n8n, start by adding the HTTP Request node to your workflow canvas and authenticate it using a predefined credential type. This allows you to perform custom operations, without additional authentication setup. Once connected, you can make custom API calls to Cisco Meraki to query the data you need using the URLs you provide, for example: you can create records in Cisco Meraki by sending POST requests to the appropriate API endpoint, such as adding new devices or users. To update existing records, utilize PUT requests with the correct parameters to modify configurations or settings. For retrieving data, use GET requests to access information on networks, devices, or alerts, leveraging the flexibility of the Meraki API within your n8n workflow.
