There is a way to provide a direct link to a Recipe page for an end user. It’s intended for cases when the end user doesn’t want to manage the elastic.io platform. Eio customer can prepare a platform and compile a link for an end user so he will authenticate and be able to activate a recipe.
Here you can see a URL Format:
https://[platform_domain]/embedded-recipe?recipeId=[recipeId]&oneTimeToken=[oneTimeToken]&contractId=[contractId]
Options:
platform_domain (required). Your elastic.io platform domain.recipeId (required). Recipe ID which you want the user to activate.oneTimeToken (required). One-time token that was generated for the user. Used to authenticate  a user in the platform.contractId (optional). Contract ID in which the user will activate the recipe. If not provided, the first found contract for the user is used.<!DOCTYPE html>

When a user successfully activates a recipe, the platform sends a message with a Recipe Deployment ID to the parent window.
{
    "action": "eio:embedded-recipe:activate-success",
    "data": {
        "recipeDeploymentId": "RECIPE_DEPLOYMENT_ID"
    }
