Mailchimp api v3 - add member to list with merge_fields - mailchimp

Question

I send this object as HTTP POST:
{
"email_address": "rickard#transticket.se",
"status": "subscribed",
"merge_fields": {
"APA": "1",
"HEJ": "2"
}
}
to https://us13.api.mailchimp.com/3.0/lists/045dfc0a43/members
and I got this response:
{
"type": "http://developer.mailchimp.com/documentation/mailchimp/guides/error-glossary/",
"title": "Invalid Resource",
"status": 400,
"detail": "The resource submitted could not be validated. For field-specific details, see the 'errors' array.",
"instance": "",
"errors": [ {
"field": "",
"message": "Schema describes object, array found instead"
}]
}
Any ideas?

Answer 1

I would have preferred to post a comment but I am still lacking in SO rep pts.
My short answer would be, without more information on the code you're using, that the error means that you have not passed a properly 'set' JSON object to the API. It will be good to remember that even though you have set it as a JSON object initially, you must be sure that the name-value pairs in your "merge_fields" must also be a JSON object.
However, if you're certain that the main and inner name-value pairs were indeed both set in JSON correctly, kindly post the code and I will try to help more.

Answer 2

This is quite easy and your code POST request is right. Maybe the Merge fields don't exist in your list. The merge_fields parameter takes a dict with some pre-defined keys. See below.
{
apikey: "yourmailmergekey"
email_address: "test_email#gmail.com"
status: "subscribed"
merge_fields: {
"FNAME: "-- First Name --",
"LNAME": "-- Last Name --",
"PHONE": "-- Phone Number --",
"ADDRESS": "-- Address --"
}
}
Hope that helps

{
"email_address": "test_email#gmail.com",
"status": "subscribed",
"merge_fields": {
"FNAME": "teste",
"LNAME": "92988410440"
}
}
