Backend Triggers
Use backend events to trigger surveys inside your mobile app and website. Additional properties can be passed with the backend events to add more context to users' responses.
- Navigate to Connections Tab > Backend Trigger on Blitzllama's dashboard
- Click on the Backend Trigger card and then click 'Enable'.
- Copy the URL(send backend trigger events on this URL) & the unique API Key 🔑 (add in the API header [x-api-key]).🔗
var request = require('request');
var options = {
'method': 'POST',
'url': 'https://events.blitzllama.com/api/v1/connections/backend/event', //copied url
'headers': {
'x-api-key': '<copied API Key>',
'Content-Type': 'application/json'
},
body: JSON.stringify({
"user_id":"user_123",
"event_name":"item_added_to_cart",
"properties": {
"id": 1,
"name": "War and Peace",
"author": "Leo Tolstoy",
"type": "hardcover",
"category": "novel"
}
})
};
request(options, function (error, response) {
if (error) throw new Error(error);
console.log(response.body);
});
event_name - this is the name of the backend trigger, which will show up in the Trigger tab on Blitzllama's dashboard after the first successful API.
user_id - the unique user identifier.
properties - JSON object that will be added to each survey responses.
Sample payload
{
"user_id":"user_123",
"event_name":"item_added_to_cart",
"properties": {
"id": 1,
"name": "War and Peace",
"author": "Leo Tolstoy",
"type": "hardcover",
...
"category": "novel"
}
}
- In the survey editor navigate to "Configure & Launch" > "Select trigger" section
- Click on "Activate with backend event" option
- Choose the backend triggers (all your backend triggers will be populated in the dropdown)
- Add event expiration time (max 100 hours). This allows you maintain relevancy of the survey questions.
- Lastly, choose where the surveys should show up on your app or website by selecting the frontend triggers from the "Select Trigger" dropdown.
In the above screenshot of a Sleep Tracking app, a sleep quality monitoring survey will be shown to the users within 2 hours of them ending their sleep ("ended sleep" event) on the app's homepage ("MainActivity" frontend trigger).
