How to make dynamic input parameters based on another query response in an Integromat app?

Question

I am implementing an API that has an endpoint which returns a list of custom fields for objects such as company, lead, etc. When creating a lead, the user should be able to enter custom fields alongside the hardcoded ones. How can this be done dynamically in the Mappable parameters of a module?

Answer 1

You can create an RPC (procedure for getting of dynamic input fields via API) and combine it with static parameters like in the example below:

Mappable parameters:

[
    {
        "name": "id",
        "type": "uinteger",
        "label": "Static parameter"
    },
    "rpc://getDynamicFields"
]
