Graph API Sends email multiple times

Question

I have a webhook that triggers an AWS Lambda function so it can be used as a hub for multiple calls to multiple different APIs, one of which is Microsoft graph. Currently one of the actions it is set up to take when the webhook is triggered is to send an email from me to me so that I can have a form of trackable notification for when the webhook event is triggered. This works perfectly except it sends the email three times at 10 minute intervals. None of the other API calls which the lambda function triggers occur more than once, so the issue seems to be with my use of the graph API specifically.

My guess is that is probably is a retry feature which kicks in when the event does not occur properly, but it does work so I am not sure why it is being triggered multiple times, or how to fix it.

Any help would be appreciated, thanks!

Hello Parker Wilson, We suggest Monitoring MS Graph requests in tenant. This issue might be due to AWS Lambda function as well. Please refer: https://stackoverflow.com/questions/57565650/called-a-lambda-function-once-its-executed-twice
