Unable to create a contact

[Spudley]

Hi.

I am trying to use the PHP Hubspot library to create companies and contacts. Creating a company works well. However I have been unable to create a contact.

Every call I have made to the create a contact has failed, returning the following message:

Client error: `POST https://api.hubapi.com/contacts/v1/contact?hapikey=***` resulted in a `400 Bad Request` response:
{"status":"error","message":"property cannot be missing or null","correlationId":"1fec847f-abfb-4583-97a9-302921c4af8d"}

I have been unable to establish what field it is complaining about; I have tried passing it the properties described in the documentation, and every combination from there that I could think of.

Here is a var_dump of of an array that is throwing the error:

array (size=1)
  'properties' => 
    array (size=10)
      0 => 
        array (size=2)
          'name' => string 'company' (length=7)
          'value' => string 'Chief' (length=5)
      1 => 
        array (size=2)
          'name' => string 'firstname' (length=9)
          'value' => string 'Bobby' (length=5)
      2 => 
        array (size=2)
          'name' => string 'lastname' (length=8)
          'value' => string 'Tables' (length=6)
      3 => 
        array (size=2)
          'name' => string 'email' (length=5)
          'value' => string 'bobby.tables@example.com' (length=24)
      4 => 
        array (size=2)
          'name' => string 'phone' (length=5)
          'value' => string '07777777777' (length=11)
      5 => 
        array (size=2)
          'name' => string 'website' (length=7)
          'value' => string 'example.com' (length=11)
      6 => 
        array (size=2)
          'name' => string 'address' (length=7)
          'value' => string 'xyz' (length=3)
      7 => 
        array (size=2)
          'name' => string 'city' (length=4)
          'value' => string 'abc' (length=3)
      8 => 
        array (size=2)
          'name' => string 'state' (length=5)
          'value' => string 'foo' (length=3)
      9 => 
        array (size=2)
          'name' => string 'zip' (length=3)
          'value' => string '123' (length=3)

Can you help explain what I'm doing wrong here?

Thank you.

Don't worry -- I solved it!

The contacts API is a V1 API call, so need properties in array format {"property":"firstname","value":"Smith"} rather than {"name":"firstname","value":"Smith"} which is how V2 API expects them. The companies API is V2 and contacts is V1, hence my confusion.
