@gaelloyoly Hello, thank for the PR. Just to help me understand the context of the change. In what situation do you get "headers_template" key in that dictionary? In other workds, why is it not 'headersTemplate' directly?

@Pijukatel I wanted to create an ad-hoc webhook and I followed the example by passing a dict with payloadTemplate and headerTemplate but none of them was used.
Then I saw that the Webhook data structure in python is using underscores :https://docs.apify.com/sdk/python/reference/class/Webhook
I guess it's to make it more "pythonic". That's why I'm using this for headers too.

@gaelloyoly Could you please describe your top level call (Which client did you use, or did you call someActor method from Apify SDK?) Because I see, that there is a function that is already responsible for conversion from underscore names:https://github.com/apify/apify-client-python/blob/master/src/apify_client/clients/resource_clients/webhook.py#L24
, but most likely there is some path that is not using this function, so that is why I want to understand how you called it.

Yes, it's the "start" method of the actor client. I'm doing something like this :

fromapify_clientimportApifyClientclient=ApifyClient("APIFY_API_KEY")client.actor("actor_id").start(run_input={"url":"input_url"},webhooks=[{"event_types": ["ACTOR.RUN.SUCCEEDED"],"request_url":"https://example.com/success","payload_template":"{{resource}}","headers_template":'{"x-custom-signature": "1234567890"}',    }],)

Yes, it's the "start" method of the actor client. I'm doing something like this :

fromapify_clientimportApifyClientclient=ApifyClient("APIFY_API_KEY")client.actor("actor_id").start(run_input={"url":"input_url"},webhooks=[{"event_types": ["ACTOR.RUN.SUCCEEDED"],"request_url":"https://example.com/success","payload_template":"{{resource}}","headers_template":'{"x-custom-signature": "1234567890"}',    }],)

Thank you for the PR and the clarification. I created issue to refactor the part of the code responsible for handling the Webhooks inputs and in the meantime let's merge your PR.

Thanks !
