Hi I used multipartpost to post data using okHttpUtil2.
I used map for values/data. But I have to send map with a map (arrays of array).
The map(array) is working fine. But the arrays of array is not working(is not inserted)

Following is the code I used.
B4X:
curl -X POST https://example.com/wp-json/wc/v2/customers \
    -u consumer_key:consumer_secret \
    -H "Content-Type: application/json" \
    -d '{
  "email": "john.doe@example.com",
  "first_name": "John",
  "last_name": "Doe",
  "username": "john.doe",
  "billing": {
    "first_name": "John",
    "email": "john.doe@example.com",
    "phone": "(555) 555-5555"
  },

for the above curl I used following b4a code

B4X:
        Dim Bill As Map
        Bill.Initialize
        Bill.Put("first_name","John")
        Bill.Put("email","john.doe@example.com")
        Bill.Put("phone","(555) 555-5555")
       
        Dim D As Map
        D.Initialize
        D.Put("email","john.doe@example.com")
        D.Put("first_name",Home.CUSDetail.Get("Username"))
        D.Put("last_name",Home.CUSDetail.Get("Username"))
        D.Put("username",Home.CUSDetail.Get("Username"))
        D.Put("billing",Bill)
       
        Dim Job As HttpJob
        Job.Initialize("Register",Me)
        Job.Username = "ck_5Xxxxxxxxxxc0"
        Job.Password = "cs_f38xxxxxxxxxxfa7"
        Job.PostMultipart("https://example.com/wp-json/wc/v2/customers",D,Null)
        Job.GetRequest.SetHeader("Content-Type", "application/json")
        Job.GetRequest.SetContentEncoding("text/plain")

Main details (email,first name,last name,username) is inserted but the Billing information is not inserted
I searched but I couldn't found what I missed.

Can anyone please help me

Does the script/programm support getting a map inside the data?
I can not see a problem in B4A Code. The server-Side must accept the data to be in this format

It says Billing is an object type.
Since it is working with the map "D" above. I though it should also work with Bill also.
I referred here https://woocommerce.github.io/woocommerce-rest-api-docs/#customer-properties
I have no idea where to check the server side is accepting it.

I tried like
JsonString = [{"password":"a","email":"newuser@gmail.com","username":"newuser"}]

B4X:
        Dim Job As HttpJob
        Job.Initialize("Register",Me)
        Job.Username = "ck_5761ffa9xxxxxxxxxxd44e662d9caf32d6b1452c0"
        Job.Password = "cs_f38b34d83dxxxxxxxxxb5be5b86e54ecdd1fc51fa7"
        Job.Poststring("https://example.com/wp-json/wc/v2/customers" , JsonString)
        Job.GetRequest.SetHeader("Content-Type", "application/json")
        Job.GetRequest.SetContentEncoding("text/plain")

Still not working. the data is not passed.

I am confused what I missed or in a wrong way.

PostString does not encode your string and most likely the receiving end is expecting an encoding string. So try StringUtil's EncodeURL method and see what happens.

Code fragment:
B4X:
Dim su As StringUtils
Job.Poststring("https://example.com/wp-json/wc/v2/customers" , su.EncodeURL(JsonString, "UTF8"))

Thanks for the reply. But same issue. No improvement.

Here is an Java OkHttp example of calling a REST API: https://howtoprogram.xyz/2016/10/31/java-rest-client-examples-using-okhttp/

Going by that example I would remove
B4X:
Job.GetRequest.SetContentEncoding("text/plain")

I would modify
B4X:
Job.GetRequest.SetHeader("Content-Type", "application/json")
to
B4X:
Job.GetRequest.SetHeader("Content-Type", "application/json; charset=utf-8")

And I would not encode the JsonString variable and just use
B4X:
Job.PostString("https://example.com/wp-json/wc/v2/customers" , JsonString)

Thanks for the effort. I will check and let you know.

yes. but how it could work in postmultipart. Also I found that postmultipart , post the request as bytes

For your additional information. the response is below

Your initial (first) post did not make it clear at all that your curl request did NOT work and therefore I tried to simulate your curl call as close as possible, which in the end was totally futile (and a waste of time). Looking through several sites, it looks like the WP API uses standard "application/x-www-form-urlencoded" POST requests, which is the equivalent to postmultipart. Another clue to that effect is this post on stackoveflow (https://stackoverflow.com/questions/36670944/wp-rest-api-v2-and-angular-http-post-request).

Sorry for the disappointment. Since I am a bigginer I couldn't get that.
I change the the contant type as 'Content-Type':'application/x-www-form-urlencoded'. But again it does not work.

Here I attached a sample project I tried. Button 1 uses "PostString" and Button 2 Uses "PostMultipart"

Edit :
I referred the following link for curl https://woocommerce.github.io/woocommerce-rest-api-docs/?shell#create-a-customer

Error Code as stated above link
Error CodeError Type
400 Bad RequestInvalid request, e.g. using an unsupported HTTP method
401 UnauthorizedAuthentication or permission error, e.g. incorrect API keys
404 Not FoundRequests to resources that don’t exist or are missing
500 Internal Server ErrorServer error
