Hook notifications

overview hooks is a notification system, used by arix, to update you on the status of your loan hooks report to your system with real time notifications when an event happens on arix you have to register to receive hooks for each relevant event type by configuring the destination and delivery method, most commonly webhooks when that event occurs, a hook is triggered and reports the updates to your system via the chosen delivery method for example, if a rail status changes to returned , a railupdated hook event would be triggered, and reported to the partner notifying them of the event this notification will only be sent out, if you have previously registered to receive this type of event ( railupdated ), and the registration is active important to access the links below you must have

of 5 minutes different intervals can be configured for a registration by the cr support team events can also be resent manually via the hooks ui, although there is a retention policy of 60 days for events in the system payload delivery wrapper when an event is sent in the form of a webhook, there will always be a wrapper around the content the actual event will be in the json's content section example loanstatusupdated event inside wrapper { "mplid" "tst", "ignore" false, "content" { "id" 0, "loanid" "c1ee19e4 791c 4f38 b581 ae6d007692a6", "status" 5, "timestamp" "2022 04 04t07 13 08

/hooks/v2/registrations editing a registration to edit an existing registration, use the same api endpoint as for creating a registration how it works include the id of the registration in the post request to modify an existing entry the api automatically determines whether to create or update a registration based on mplid hookname if a registration already exists for the given mplid/hookname combination, the api will update it instead of creating a new one if no matching registration is found, a new one will be created when editing a registration via the ui , any stored passwords or tokens will be shown hashed on the ui for security reasons, you will need to re enter these credentials when modifying the registration sample request in curl post /hooks/v2/registrations in the

hookname, assuming there is only one registration per combination of mplid/hookname in certain use cases, you might want to create two registrations for the same event for example, one web hook, and one email hook to do this, you need to supply a new guid for the id field of the registration webhook attributes attribute description id string this field can be null or populated with the registration guid for the registration null when creating a new registration guid when updating or unsuspending an existing registration applicationname string should always be cos lending hookname

to do this you must create a slack bot with permissions to write to a channel in your workspace retrieve the auth token of the slackbot add the slackbot to the slack channel that you wish to register register the channel to receive events on the cos lending hooks ui, or via the api payload below important registering to a slack channel is not recommended if automation is needed for complete

"slack", "authtoken" "your slack api bot token ", "channel" "the channel name you must also add your slack bot to this channel" }, "suspended" false } email hook registration hook events can also be sent to your email address, or group email address register the channel to receive events on the cos lending hooks ui, or via the api payload below important registering to receive events via email is not recommended if automation is needed for complete automation, it is recommended to use "web" hooks instead { "id" null, "applicationname" "cos lending", "hookname" "loannoteadded", "hookcorrelationid" "your 3 letter mpl id", "options" { "hooktype" "email", "to" \[ "email address" ], "cc" \[ null ], "bcc" \[ null ] }, "suspended" false } testing webhook registration to test registering webhooks, configure a url for the specific event you are registering to if a url is not yet available, then you can use the webhook site as a temporary test solution follow these instructions to test the webhooks to register your url to receive webhook events go to https //webhook site/ click new on the top menu the site returns your unique url copy to clipboard your unique url if you already have other webhooks registered, the browser might automatically direct you to the url you've used 4\ paste the copied url into the options uri field of the json body 5\ send the registration api call with hook type "web" to register for webhooks the response field result id is the registrationid of the event you can find the registration id with the call get hooks/v2/registrations repeat the process for each event that you want to register for delete /hooks/v2/registrations request url https // /hooks/v2/registrations use this call to unregister any hook event you are registered to sample request in curl del /hooks/v2/registrations curl location request delete 'https //lendingsandbox crbcos com/hooks/v2/registrations?id=eb62ffbd 7ed4 4146 be48

required query parameter parameter name parameter type data type description id query long the registration id of hook registration to remove sample response in json del /hooks/v2/registrations there is no response in the image below because the hook registration was deleted successfully you can use the arix test collection in postman to practice unregistering from an event in the postman collection, delete registration click the tab, params in the key field, enter id in the value field, enter the registration id number that you received when you registered to the event click send
