How to add cutom customer attribute field to call rest api via create new customer

Question

I have created a custom customer attribute(mobile_number) and set default value of customer create account.

I added mobile number to customer_attribute:

    $customerSetup->addAttribute(Customer::ENTITY, 'mobile_number', [
        'type' => 'varchar',
        'label' => 'Mobile Number',
        'input' => 'text',
        'required' => true,
        'visible' => true,
        'user_defined' => true,
        'sort_order' => 1000,
        'position' => 1000,
        'system' => 0,
    ]);

Now, its added, when created account manually its working fine and this mobile number details stored in customer_entity_varchar table.

I need to create a customer using rest api. I followed this link to send request via curl it throws an exeption that Mobile Number is required.

Curl Request:

curl -X POST "http://www.magento_server.net/index.php/rest/V1/customers" -H "Content-Type:application/json" -H "Authorization: Bearer xhfyo8cfvknpyd5dwuupe34uosh6tuhj" -d '{
    "customer": {
      "email": "person@email.net",
      "firstname": "First",
      "lastname": "Last",
      "storeId": 1,
      "websiteId": 1

    },
     "password": "Abc@123456",
     "mobile_number": "123-123-1234"
  }' | json_pp

Error:

Answer 1

The custom attribute mobile_number should be inside custom customer attribute data:

{
  "customer": {
    "email": "person@email.net",
    "firstname": "First",
    "lastname": "Last",
    "storeId": 1,
    "websiteId": 1,
    "custom_attributes": [
     {
       "attribute_code": "mobile_number",
       "value": "23456798"
     }
    ]
  },
  "password": "Abc@123456"
}
