what's the server message format for passing back variableValues in the POST request?

The API playground doesn't let me add in variableValues afaik so just want to make sure I'm capturing them correctly. Would think it is:
message.variableValues.[variable_name], but that doesn't seem to work

@Sahil
It seems like you're trying to access variable values within the API playground. The correct way to access variable values would typically depend on the specific API's documentation and the structure of the data it provides. If you're working with a JSON message, you might access a variable using a path similar to message.variableValues.variable_namemessage.variableValues.variable_name without the square brackets.

However, if message.variableValues.[variable_name]message.variableValues.[variable_name] is not working as expected, it's possible that the syntax might be incorrect or the API playground you're using may have specific rules for accessing variables.

Could you please provide more details or clarify the context in which you're trying to capture these variable values? If you're referring to a specific part of the VAPI documentation or a feature within the API playground, that information would be helpful in assisting you further. If this is a feature that should be available but isn't working as expected, it might be best to reach out to the support team for the API playground you're using.

You can continue this conversation by mentioning me in the message.

message.variableValues.variable_name is not working. I'm just trying to pass in a variableValue titled email and then retrieve that same variableValue in the post request

does it need to be messages.assistantOverrides.variableValues.variable_name?

it's not working - this is the error I keep getting from my webhook function:

my use case here is I want to pass in a customer's email address as a variableValue and then make sure I can tie the POST request I get back from Vapi to the appropriate customer via their email so I can update their database entry

@Sahil I will be available today https://discord.gg/E4TEgnHV?event=1329840374939914240
From error response of your code you have shared it's look like your have undefined variable and you just need to define it.

Can variableValues be changed mid-call, e.g. by a tool call?

My use case:

Squad member 1 talks to caller, gets data, e.g. address
Squad member 1 calls tool, which calls PATCH /call/:id to update membersOverrides.variableValuesmembersOverrides.variableValues
Squad member 1 transfers to Squad member 2
Squad member 2 references the variables

Right now this does not work, could you please share the best practice for this?
