SugarCRM API - Filter POST - Related Module Fields - sugarcrm

Question

I'm trying to retrieve, using REST API, a list of records and one of its related module fields. Let's assume Accounts and Opportunities.
So, API Documentation (in the GET Filter) talks about defining related module in the fields parameter:
According to the same documentation, it would provide a result similiar to:
That's exactly what I need, but I'm trying to achieve this using the POST method. So, following the same path, I'm sending (using Postman):
PS: I tried all combinations of double quotes. Escaped, not escaped, with or without it, all of them give me the same result, that is:
The message is in pt-BR but it means "One of your request parameters is wrong". The HTTP status code is 422 - Unprocessable Entity.
What am I doing wrong? I tried everything and just don't know how to make it work. Looks like the documentation talks about something that simply don't work or doesn't exist.

Okay, so after some research, it seems that Postman uses something similar to Chrome and it isn't really possible to send GET requests with the values in the body. However, you can...
Encode the values into the URL and send it through Postman:
https://yoursite.com/rest/v10/Accounts?filter%5B0%5D%5Bopportunities.date_modified%5D%5B%24gte%5D%3D2016-02-29T00%3A00%3A00&fields=cpf_c,opportunities&max_num=10
Use curl:
curl -X GET -H Host:yoursite.com -H OAuth-Token:d49c8fd4-0ae0-d9fb-7ab8-5846e5a3fa86 -H Cache-Control:no-cache -d '{"filter":[{"opportunities.date_modified":{"$gte":"2016-02-29T00:00:00"}}],"fields":["cpf_c","opportunities"],"max_num":"10"}' https://yoursite.com/rest/v10/Accounts
Or build the HTTP request directly, and include the body:
GET https://yoursite.com/rest/v10/Accounts HTTP/1.1
Host: yoursite.com
OAuth-Token:d49c8fd4-0ae0-d9fb-7ab8-5846e5a3fa86
Cache-Control:no-cache
{"filter":[{"opportunities.date_modified":{"$gte":"2016-02-29T00:00:00"}}],"fields":["cpf_c","opportunities"],"max_num":"10"}
To test this, I created 3 Accounts, 2 of which had an Opportunity linked. The response was this when I used "name" instead of your "cpf_c" field:
{
"next_offset": -1,
"records": [{
"id": "64417139-459c-852f-3a73-5846ed1245c2",
"name": "another account with opp",
"date_modified": "2016-12-06T16:54:29+00:00",
"opportunities": {
"next_offset": -1,
"records": [{
"id": "32d1d320-c560-92d6-7def-5846eda786da",
"date_modified": "2016-12-06T16:55:06+00:00",
"_acl": {
"fields": {}
},
"_module": "Opportunities"
}]
},
"_acl": {
"fields": {}
},
"_module": "Accounts"
}, {
"id": "48dc47dd-bbf1-816d-b0ac-5846e6dd9e21",
"name": "test with opp",
"date_modified": "2016-12-06T16:23:33+00:00",
"opportunities": {
"next_offset": -1,
"records": [{
"id": "79c3bf6f-6c2b-7945-09f7-5846e6c610d7",
"date_modified": "2016-12-06T16:24:20+00:00",
"_acl": {
"fields": {}
},
"_module": "Opportunities"
}]
},
"_acl": {
"fields": {}
},
"_module": "Accounts"
}]
}
Hope this helps.
