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

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

1. Go to Admin >> System >> Manage Hooks.

2. 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).

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.
