Trigger: Webhook (URL)

About

This trigger will fire on this device when the specified web URL is called from anywhere.

More information here. https://medium.com/@macrodroid/introducing-the-webhook-trigger-a760e2ee140d

Warning

that the URL is unique to this device and the URL will change if the application is reinstalled (or all application data is deleted).

This feature uses Firebase Cloud Messaging to notify the device via the backend server, therefore it is not functional on devices that lack Google services (such as Alexa tablets etc.)

Request configuration

Identifier

The identifier is what is after the base url.
Base URL:

https://trigger.macrodroid.com/c306bcd7-5f78-4895-bee4-677d4d/

E.G. The identifier would be 'mywebhook'
https://trigger.macrodroid.com/c306bcd7-5f78-4895-bee4-677d4d/mywebhook

IP address whitelist

You can support one or more IP addresses so that the webhook is only activated from specific IP addresses.
It also supports magic text '...'

Magic text list

Save body to string variable

If your HTTP POST request contains any text format, you can save it in any string variable.

Note that due to limits imposed by Firebase Cloud Messaging the maximum body text length is 3800 characters.

Webhook management

Export device ID to new device

You will be asked to create a password (it will be linked to your current device ID) and you can import it later in case your device is damaged or you update your current device.

Later you can use the 'Import device ID from another device' option to restore your previous Device ID.

Import device ID from other device

You will be asked for the Device ID and password and you will be able to correctly import the Device ID.

Generate new device ID

This will assign a new device id to this device. Existing webhook links for this device will no longer function.
To get a new device ID you just need to check the 'I have read and understood' box
and you can generate your new device ID.

Example

This macro will receive values by webhook and speak them by TTS.
