IFTTT’s Maker channel with PHPoC Blue.

[Jack Kim]

This article shows how to send a notification to Android or iOS devices with Maker channel.
You need IFTTT account and any Android or iOS device with the IF app installed.


1. Create a recipe



Click this and search Maker channel.



1.1 Step 1

- Choose Maker icon and click Connect and then Done.






1.2 Step 2 ~ 3

- Click Continue to the next step and Receive a web request.
- Enter a event name. In this demo, I create SWITCH event.




1.3 Step 4 ~ 5

- Click that and search Notification and choose IF Notification.
- Choose Send a notification action.




1.4 Step 6

- There are four properties for this action.
- EventName is the trigger name. Value1 ~ 3 are user defined values. OccuredAt is the time when the trigger is fired.



- I changed the text like below.




1.5 Step 7

- Click Create Recipe.




2. How to trigger event

- Go to the Maker channel.



- A key in the “Your key is” section is very important. You need the key to trigger your event.
- Click How to Trigger Events.



- An event triggered by HTTP POST or GET web request.
- Fill {event}, “value1”, “value2”, “value3” and then click Test it then you can receive a notification on your device IF app installed.
