Hello,
It should be noted that this endpoint and method you are using is for sending an individual contact. If you are trying to send multiple contacts, the payload will be different. For the full documentation on our bulk endpoint, see https://developer.constantcontact.com/docs/bulk_activities_api/bulk-activities-import-contacts.html
Assuming that the slashes are simply escaping the quotation marks in your JSON from C#, here's what I see:
- There should be no parameter for activity_type=ADD_CONTACT. This was used for bulk imports with our old V1 API and is not used with this method in V2.
- The access token not added as a parameter, but is used in an Authorization header as "Bearer xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" to properly authorize.
- The entire payload should be a single object and not an array.
- Your field and property names should be all lowercase.
- You cannot use null as values for any fields, you would simply use an empty string ("").
- The opt_in_source on an email address is read only, and you set the source as a URL parameter.
- The ID on an address is read only and is assigned by Constant Contact when it is created.
- The address_type needs to be either "PERSONAL" or "BUSINESS", and must be all caps.
- If you are setting a state_code, the state needs to match the name of that state. E.g. state_code of CA means the state field needs to be "California" -- if you are using the state_code field, you can omit the state field.
Here is an example of a call to that endpoint:
POST https://api.constantcontact.com/v2/contacts?action_by=ACTION_BY_OWNER&api_key=xxxxxxxx

Content-Type : application/json

}
]
}
