POST API Call Failing with 405 Error in Azure Static Web Apps

POST API Call Failing with 405 Error in Azure Static Web Apps

Shreyas Rastogi 225

A Blazor WebAssembly app is configured to connect to a SQL database following the guidance in this article: How to host static web apps.

The API status is healthy, and GET calls work as expected. However, POST calls to add records to the database return a 405 error, indicating that only GET, HEAD, and OPTIONS methods are allowed.

Is there a configuration or change required to enable the POST API call to work?

A 405 (Method Not Allowed) is commonly a coding error. We cannot see the controller/action definition, model, or client code so there's not much we can do to help you. Is there anyway you can provide a code sample that reproduce the 405?

Here is the code for reference

// Send data to database

var data = new {

Text = result.Text,

Email = result.Email,

PhoneNumber = result.PhoneNumber

};

var endpoint = "/rest/UserFeedback";

var dbResponse = await Http.PostAsJsonAsync(endpoint, data);

if (dbResponse.IsSuccessStatusCode)

{ Response += " and saved to the database.";

}

else

{Response += " but failed to save to the database.";

}

this is really a question about the Data API Builder application. You appear to be using the REST API. did you enable posts? we would need to see the "rest" section of the entity definition from the config file to help.

Hi @Bruce (SqlWork.com)

below is the config file with rest section , i have configured actions to * .

entities": {

"UserFeedback": {

  "source": {

    "object": "dbo.UserFeedback",

    "type": "table"

  },

  "graphql": {

    "enabled": true,

    "type": {

      "singular": "UserFeedback",

      "plural": "UserFeedbacks"

    }

  },

  "rest": {

    "enabled": true

  },

  "permissions": [
