How can I adapt an Airtable curl POST command for C# or VB.NET?

In my .NET application, sending records to Airtable triggers a 422 error. I suspect the JSON payload or header setup is off. See the updated code snippet:

using System.Net.Http;
using System.Text;
using System.Threading.Tasks;

public async Task SubmitEntry()
{
    using(var httpClient = new HttpClient())
    {
        httpClient.DefaultRequestHeaders.Add("Authorization", "Bearer NEW_API_KEY");
        var jsonPayload = "{\"fields\":{\"ItemName\":\"example\",\"Category\":\"test\",\"Owner\":\"userXYZ\"}}";
        var httpContent = new StringContent(jsonPayload, Encoding.UTF8, "application/json");
        var response = await httpClient.PostAsync("https://api.airtable.com/v0/appNEWID/Records", httpContent);
        string reply = await response.Content.ReadAsStringAsync();
        System.Console.WriteLine(reply);
    }
}

I had a similar experience where a mismatch in the expected JSON format led to the 422 error. I learned that careful validation of every key in the JSON is crucial. In one case, a typo in a field name not only disrupted data processing but also made it almost impossible to identify the error from the server’s vague message. After thoroughly cross-checking each parameter with Airtable’s documentation, I was able to pinpoint the mismatch. Therefore, ensuring type consistency and exact key naming is essential when transitioning from a curl command to a .NET implementation.

I encountered a similar issue while integrating with an external API. In my experience, paying close attention to the detailed requirements of the API can help resolve these kinds of errors. I eventually found that even minor inconsistencies in the JSON structure or the endpoint URL, such as an extra character or a misplaced key, can trigger errors like the 422 one you mentioned. Using a JSON validator to verify the payload and double-checking the API documentation provided me with the insights I needed to correct the issue.
