Welcome to the Make community!
To trigger another scenario, you can use the HTTP → Custom Webhook method.
The calling scenario uses a HTTP module to make a request to another scenario’s Custom Webhook trigger module’s URL. You can pass data via JSON, form data, or query parameters.
You can also use the Make API to trigger another scenario to save an operation, only if there is no data to pass.
Hope this helps! Let me know if there are any further questions or issues.
