Hello, I was wondering: is there any way to add the hubspot signature header in a post request made in a custom code workflow node? I am using hubspot client v8, axios, nodejs.

Hi, @filomontani Here’s the documentation on adding this signature to your requests when using Workflows — [Verify request signatures in workflow webhooks](https://knowledge.hubspot.com/workflows/how-do-i-use-webhooks-with-hubspot-workflows#verify-request-signatures-in-workflow-webhooks)

Here is the additional documentation:

Thanks but I’m not using a webhook: I’m using a custom code action
