Good afternoon,
I am trying to connect my API to the app builder and when I do I see

I can link my get apis, and these are working as expected but the post requests I have are all greyed out.

Below is the post method within my asp.net api

        [HttpPost("addIngredient")]
        public async Task<ActionResult<Guid>> addIngredient([FromBody] NewIngredient ingredient){

            var newId = new OutputParameter<Guid?>();
            var allergenId = new OutputParameter<Guid?>();
            var nutrientId = new OutputParameter<Guid?>();

            Guid libraryId = new Guid("CDDF26FE-D224-4916-8060-33F62E48F95E"); 
            Guid groupId = new Guid("7993BFEE-E676-4A9A-A476-026953FB1594"); 

            if (ingredient == null)
            {
                return BadRequest();
            }
            else
            {
                 await _foodDataServicesContext.GetProcedures().usp_InsertOrUpdateIngredientAsync(null,libraryId, groupId, ingredient.foodCode, ingredient.displayName, ingredient.displayName, "Description", 0, 0, 0, 0, 0, ingredient.costPerKilo, ingredient.internalReference, newId);
                foreach (AllergenIngredient allergen in ingredient.allergens)
                {
                    await _foodDataServicesContext.GetProcedures().usp_Allergen_Ingredient_Link_InsertAsync(new Guid(allergen.AllergenId), newId._value, allergenId);
                }
                foreach (NutrientIngredientValue nutrientValue in ingredient.nutrients)
                  {
                    await _foodDataServicesContext.GetProcedures().usp_Nutrient_Ingredient_Values_InsertAsync(new Guid(nutrientValue.NutrientId), newId._value, nutrientValue.NutrientValue, nutrientId);           
                  }
                 

                return Ok(newId._value);


            }

Thnaks
