No just add the tool call.

do you mean, to add it into CreateCall? Something like this?

{"assistant": {"model": {
            "semanticCachingEnabled": True,
            "tools": [
                {
                    "type": "function",
                    "async": True,
                    "function": {
                        "name": "sendMessage",
                        "description": "Sends message to customer",
                        "parameters": {
                            "type": "object",
                            "required": ["fromPhoneNumber"],
                            "properties": {"fromPhoneNumber": {
                                    "type": "string",
                                    "description": "Phone number from which AI is calling",
                                    "required": [None]
                                }}
                        }
                    },
                    "server": {
                        "url": "https://my.api.ai/sendMessage",
                        "secret": "mySecretApiKEY"
                    }
                }
            ]
        }}}

Are you doing a cURL?

I'm calling it from my python service

I don't know if it's discord formatting but that tool looks very wrong - but I barely know Python. You can compare it to what I attached. I dont use dashboards assistants but same thing.

yea it looks different, it's weird because I used this link: https://docs.vapi.ai/api-reference/calls/create-call https://cdn.discordapp.com/attachments/1281244217628295223/1281252455849398326/createCallWithFunctionCallExample.txt?ex=66db0ad5&is=66d9b955&hm=c7491772dfa2d985cf50bb12d8a6dc0ef10f77976e521ec70fefa8b2a99cfe0a&

Same thing. I only use API.

ah yes, sorry you are correct
