Event Grid - HMAC request signing

Neilson Ma 6 Reputation points

I'm trying to implement a webhooks system for my application using Event Grid webhooks. In order to secure the payload, many examples online have pointed towards request signing using HMAC and I was wondering if this would be possible using Event Grid. I'm using the Event Grid publisher client SDK to publish events but I'm unable to find anywhere where I can send headers for the calculated signature.

    Hi @Neilson Ma Thanks for reaching out. No, we don't have support setting the custom headers during while publishing, however you can define custom headers (with static or dynamic values from payload) on event subscription and Event Grid sets those headers during delivery.

    let me know incase of further queries, I would be happy to assist you.
