How can I authenticate with the Twitter API from Zapier?

Question

I'm trying to call the Twitter API from Zapier using "Webhooks by Zapier", but do not manage to authenticate correctly via OAuth 1.0.

Using a REST client like Postman, it is a piece of cake. You just pass the consumer key, consumer secret, token and token secret, and set the signature method to HMAC-SHA1. Plus you check "Encode OAuth signature". The client calculates the signature.

I'm looking for a way to calculate this signature in Zapier (possibly using the built-in Python and Javascript modules), but haven't managed so far. If possible, it opens a whole range of possibilities (using the easy connectivity to other apps).

Similar to How do I make a Tweet in Zapier code.

Get that access token and then use your own token and set a header!
