Get all API fields definitions from Podio application - api

Question

Responses from Podio API returns an JSON array of items with a fields property. Each field carries its values and its config.
For example a category field for the Gender:
{
"type": "category",
"field_id": 219922852,
"label": "Gender",
"values": [
{
"value": {
"status": "active",
"text": "Prefer not to say",
"id": 3,
"color": "F7F0C5"
}
}
],
"config": {
"settings": {
"multiple": true,
"options": [
{
"status": "active",
"text": "Male",
"id": 1,
"color": "DCEBD8"
},
{
"status": "active",
"text": "Female",
"id": 2,
"color": "F7F0C5"
},
{
"status": "active",
"text": "Prefer not to say",
"id": 3,
"color": "F7F0C5"
}
],
"display": "inline"
},
"mapping": null,
"label": "Gender"
},
"external_id": "gender"
},
How can I fetch the config without having to query a specific item?
Is there a way to get every field in the response? Because if the queried item does not have a field value set, Podio doesn't return it in the response.
I would like to get the field config for ALL the fields. If possible, with a single API request. In particular I am interested in all the possible values (in case of Category or Relationship fields) so that I could match them with local values I have.
This way I can use the field structure to programmatically map some local values to the format required by the Podio API; and then generate a fields payload that to update/create Podio items via an API calls.

You can request the Podio Get App method to get the app configuration.
