Custom params: object and array

Custom Apps

Hi folks,

I have a challenge with creating a proper module configuration

I’m doing it for this endpoint https://api-docs.mailtrap.io/docs/mailtrap-api-docs/7d76bbcbcf6e3-create-a-new-contact#response-body

so actually here is a payload

  "contact": {
    "email": "john.smith@example.com",
    "fields": {
      "first_name": "John",
      "last_name": "Smith"
    },
    "list_ids": [
      1,
      2,
      3
    ]
  }

Just fields is dynamic, so a user1 can have 1 fields, user2 - 5 fields. It’s all depends on his configuration

With params I tried to use

  {
    "name": "fields",
    "type": "collection",
    "label": "Contact Fields",
    "required": false,
    "default": {},
    "help": "Define additional fields as key-value pairs. Example: {\"first_name\": \"John\", \"last_name\": \"Smith\"}."
  },
  {
    "name": "list_ids",
    "type": "text",
    "label": "List IDs (JSON array)",
    "required": false,
    "default": "[]",
    "help": "Enter the contact list IDs as a valid JSON array. For example: [1,2,3]."
  }

but in connection I got an error

{
  "url": "{{common.endpoints.contacts}}/api/accounts/{{parameters.account_id}}/contacts",
  "method": "POST",
  "headers": {
    "Accept": "application/json",
    "Content-Type": "application/json",
    "Api-Token": "{{connection.apiKey}}"
  },
  "qs": {},
  "body": {
    "contact": {
      "email": "{{parameters.contact_email}}",
      "fields": {{parameters.fields}},
      "list_ids": {{ JSON.parse(parameters.list_ids) }}
    }
  },
  "response": {
    "output": "{{body}}"
  }
}

Thou I can’t save it in connection as got some validation error.

Can you help? What I’m doing wrong? Thanks a lot!
