(Step 2) Now login in to the SendGrid website, then under the left-hand side menu go to the 'Settings' ==> 'Sender Authentication'. At 'Single Sender Verification' click on the 'Get Started' button. (Step 3) Let'

The main objectives of this article are: Create HTTP Delete Endpoint In API Project. VueJS Application To Invoke The Delete API. Create HTTP Delete Endpoint In API Project: Let's create the HTTP Delete endpoint in the API project. API_Project/Controllers/BeachController.cs: [HttpDelete] [Route("{id:int}")] public async Task<IActionResult> Delete(int id) { var beachToDelete = await _myWorldDbContext.Beach.FindAsync(id); if (beachToDelete == null) { return NotFound(); } _myWorldDbContext.Beach.Remove(beachToDelete); await _myWorldDbContext.SaveChangesAsync(); return Ok(); } (Line: 1)The 'HttpDelete' attribute allows only HTTP delete requests to consume the action method. (Line: 2) The 'Route' attribute is defined where we need to pass the integer 'id' value in the route. (Line: 5) Based on the 'id' value try to fetch the record from the database. (Line: 6-9) Checking whether records exist in the database or not. (Line: 10) U
