Sample Redirect on Subscribe

Redirect to a URL after subscription

<div id="billflow-embed"></div>
<script>
  window.billflowSettings = {
    billing_page_id: "B4bD7TzIKxnsZfcgJoFk",
    email: "[e-mail]",
    handleResponse: async function(payload) {
      console.log("Event ", payload.event);
      console.log("Response Object ", payload.response);
      //Redirect on Signup example
      if (payload.event == "create_subscription") {
        window.location.href = "https://google.com";
      }
    }
  };
  (function() {
    var s = document.createElement('script');
    s.src = 'https://js.billflow.io/billflow-embed.js';
    s.async = true;
    s.type = 'text/javascript';
    var x = document.getElementsByTagName('script')[0];
    x.parentNode.insertBefore(s, x);
  })();
</script>

Sample Redirect based on Tier Subscribed

Sample Pricing Page redirect for specific tier

Redirect to a URL after subscription

<div id="billflow-embed"></div>
<script>
  window.billflowSettings = {
    "billing_page_id": "B4bD7TzIKxnsZfcgJoFk",
    "loader": "2",
    handleResponse: async function(payload) {
      let event = payload.event;
      let response = payload.response;
      //Redirect for free plan (update tiername check to yours)
      if (event == "select_plan") {
        let tierName = response.tier.tierName;
        if (tierName == "Starter") {
          window.location.href = "https://google.com"; //CHANGE ME
        }
      }
    }

    s.type = 'text/javascript';
    var x = document.getElementsByTagName('script')[0];
    x.parentNode.insertBefore(s, x);
  })();

Sample Existing User check

Skip subscription creation if a user already exists

window.billflowSettings = {
	handleResponse: async function(payload) {
		// Implement pre subscribe hook example
    let { event, response } = payload;
		if (event === 'pre_subscribe') {
			// implement your logic for checking user exist in your system
			let { email, service, tier } = response;
			let exists = true;
			// throw an error for billflow to stop the subscribe action.
			if (exists) {
				throw {
					// displays an error message in servicebot
					message: 'User already exist, please login.',
					callback: () => {
						// call back to redirect or other actions you want to take.
						window.location = '/login';
					}
				};
			}
		}
	}
}

      // your code here 
      console.log("response", response)
      if (response.event === "add_coupon") {
        const coupon_id = response.response.coupon.id
        const bad_coupon = 'BAD'
        if (coupon_id == bad_coupon) {
          throw ({
