Hi @Universus 

If you know the Model internal ID (bottom value), then you can use the ‘CUSTOM’ tab to set that value and try testing.

I’ll try it out and let you know ^  (in a few hours).

Yeah, I should have tried that first  

I’ve only been able to use Claude 2.1 with the custom field. I get an error for 3-opus and 3-sonnet:

Failed to create a conversation in Anthropic (Claude)

"claude-3-sonnet-20240229" is not supported on this API. Please use the Messages API instead.

I’m still new to Zapier so I might be doing something wrong on my end.

True, I get the same error. 
Good to know it works for the 2.1

It's possible to get Claude Opus and all other models working through a Webhook. This requires Premium functionality to perform a Custom Request.

You want to do a POST call to the messages endpoint: https://api.anthropic.com/v1/messages

In the Data field you will pass the model name, tokens, your prompts and other parameters & even image URLs if you want to use multi-modal capabilities.

More documentation here (copy from the Python code samples).

In the headers it's important to pass your API key which you can get here: https://console.anthropic.com/settings/keys

With all of this setup, you should be able to successfully make a call and verify that it's working by checking the model name in the output.

@Serge 

Thank you for your answer, 

It is clearly the best one.   A real solution. 

Sadly, I don’t seem to be able to modify who gave the best answer…!   but thank you for this one !
