Manage Hooks

Hooks are a mechanism to trigger custom code on the occurrence of events. In other words, Hooks are notifications sent to any external application (which can be accessed through a web address) from Mifos X in the format the external application wants. Each template during hook creation represents custom behavior on what actions should be taken on the triggering of a registered event for a hook. The action taken might be firing an HTTP request to another server or executing an internal code.

In order for Mifos X to send webhook payloads, your server needs to be accessible from the Internet. Mifos X will send along a few HTTP headers to differentiate between event types.

X-Mifos-Entity - The entity type that was triggered.
X-Mifos-Action - The action triggered on the entity type.
X-Mifos-Platform-TenantId - The tenant which experienced the event.

You can create two types of Hooks using Hook Templates.

Web
SMS Bridge

Create an SMS Bridge Hook

Note :i) You need to clone https://github.com/mgeiss/mifos-twilio-bridge and do a gradlew bootRun to start the application which will act as a bridge between Mifos X and Twilio.

ii) Your mobile number should be registered to twilio. (See the link for more information: http://www.twilio.com/help/faq/phone-numbers )

Go to Admin >> System >> Manage Hooks.
Click on 'Manage Hooks' and then click on '+Create a Hook' to see the following window. (Here, select Hook Template as "SMS Bridge" from drop-down menu)

3	Active	None	Please Check it to trigger the hook.
4	Payload URL	None	http://localhost:9191/modules/sms, Provide this as Payload URL only for "SMS Bridge", not for "Web" hook template.
5	Phone Number	None	This field has to be the phone number with which the person registered for the SMS service provider (Example: Twilio) and not some random number.

You can select any one of the event for which the hook is triggered for. (Note: The only 2 events in Mifos X currently supported by the bridge application are CREATE CLIENT and REPAYMENT LOAN. The bridge application won't react to other events registered for the SMS Bridge Hook.)

Associate a UGD template with an SMS Bridge Hook: Click Here to watch the tutorial video.

Note: i. Do not create an SMS Bridge hook with your own mobile number if you have not registered for Twilio.

ii. If you create multiple clients in Mifos X with the same mobile number for testing (by deleting the client and creating a new one), that might not be supported by the bridge application because of unique mobile number constraints.

iii. If you somehow lose/clear the database contents for bridge application, it is better to delete the hook in Mifos X and create a new one.
