Add Recipe to Collection - Plugixa Recipe for WordPress

Add Recipe to Collection - Plugixa Recipe

POST /plugixa-recipe/v1/collections/{id}/recipes

Add a recipe at the end of a collection; in a meal plan, on a given day and meal.

Needs the plugixa_recipe_edit capability, or WordPress’s edit_posts (Contributor and up). Needs Plugixa Recipe Pro with the Collections app on.

Note. Nothing stops the same recipe being added twice unless both day_number and meal_type are set: the duplicate check never fires in a plain collection or cookbook, nor in a meal plan entry without a day and a meal. Check List Collection Recipes first.
