# If Pay Then That
[](https://www.npmjs.com/package/ifpaytt)
[](https://github.com/ElementsProject/ifpaytt/blob/master/LICENSE)
[](http://makeapullrequest.com)
[](https://webchat.freenode.net/?channels=lightning-charge)
Use Bitcoin Lightning payments as the _trigger_ for IFTTT (If This Then That) _actions_.
Powered by :zap: [Lightning Charge](https://github.com/ElementsProject/lightning-charge) and [paypercall](https://github.com/ElementsProject/paypercall).
## Install
```bash
$ npm install -g ifpaytt
```
## Setup
Setup [Lightning Charge](https://github.com/ElementsProject/lightning-charge), then:
1. Get your IFTTT maker key from [IFTTT's Webhook settings page](https://ifttt.com/services/maker_webhooks/settings)
(shown as `https://maker.ifttt.com/use/[MAKER-KEY-HERE]`).
2. Open the [new applet page](https://ifttt.com/create), click "this", enter "Webhooks", click "Receive a web request",
enter a descriptive event name prefixed by `ifpaytt_` containing only numbers, lowercase letters and `_`
(e.g. `ifpaytt_lightup_room404` or `ifpaytt_vend_machine137_item56`),
and click "Create Trigger".
3. Configure your "then" action and finish creating the IFTTT applet.
4. Start the `ifpaytt` server:
```bash
$ ifpaytt --charge-token [mySecretToken] --ifttt-key [myMakerKey] --currency BTC \
--price-lightup_room404 0.00001 --price-vend_machine137_item56 0.000063
Running on http://localhost:6000
```
That's it! The server is now ready to accept payments and trigger IFTTT actions.
## Paying to trigger actions
Users can access the IFTTT action through a three-part process:
1. Send an empty `POST` request to `/{event-name}` to get the BOLT11 payment request and the `X-Token` header:
```bash
$ curl -i -X POST http://localhost:6000/lightup_room404
HTTP/1.1 402 Payment Required
X-Token: lmbdmJeoSQ0ZCB5egtnph.af1eupleFBVuhN2vrbRuDLTlsnnUPYRzDWdL5HtWykY
Content-Type: application/vnd.lightning.bolt11
lnbcrt8925560p1pdfh7n2pp54g5avyupe70l988h30u0hy8agpj2z7qsveu7ejhys97j98rgez0...
```
2. Make the payment:
```bash
$ lightning-cli pay lnbcrt8925560p1pdfh7n2pp54g5avyupe70l988h30u0hy8agpj2z7qsveu7ejhys97j98rgez0...
```
3. Send the request again, this time with the `X-Token` header echoed back and optionally
with `value1`, `value2` and `value3` in the request body (passed along to IFTTT):
```bash
$ curl -i -X POST http://localhost:6000/lightup_room404 \
-H 'X-Token: lmbdmJeoSQ0ZCB5egtnph.af1eupleFBVuhN2vrbRuDLTlsnnUPYRzDWdL5HtWykY' \
-d value1='brightness=80,color=red'
HTTP/1.1 200 OK
Content-Type: text/plain
Congratulations! You've fired the ifpaytt_lightup_room404 event
```
(if `value[1-3]` are not set, they'll [automatically be populated](https://github.com/ElementsProject/ifpaytt/blob/master/src/app.js#L40-L42)
with some useful information about the payment.)
