Send text message using external gateway

Yes,   is right. You should be able to adapt the code I've been using for the Twilio gateway to get this working via GOV.UK Notify. If needed, you can send me an temporary API key and templateid and I'll try to get it working.

Thanks Niels, that was a good series of videos so I understand a lot more now. I did run into this issue iRulesLX error: error: 01070711:3: boost::filesystem::status: Permission denied: (f5.com) when I installed the module so had to follow that workaround but I think everything is in place now and I just need to get the code right. I'll post the correct code here if it works or (more likely) I may need to ask another question.

Hi Niels

I have followed your instructions and we have tried to adapt your code using the guidance on gov.uk. I am getting this error:

Rule /Common/ilxplugin_gov_uk/irule_gov_uk <ACCESS_POLICY_AGENT_EVENT>: sendOTP failed for telephoneNumber: +447767826522, ILX failure: ILX timeout. invoked from within "ILX::call $rpc_handle sendOTP $generatedOTP $telephoneNumber "

Can you see what the error could be? I can give you the apiKey and templateId if needed

This is my iRule

when ACCESS_POLICY_AGENT_EVENT {
if { [ACCESS::policy agent_id ] eq "gov_uk" } {

set generatedOTP "[ACCESS::session data get session.otp.assigned.val]"
set telephoneNumber "[ACCESS::session data get session.ad.last.attr.extensionAttribute1]"

if {[info exists generatedOTP] && ($generatedOTP eq "")} {
log local0. "Error: generatedOTP variable is empty; no OTP sent for $telephoneNumber."
return
}

if {([info exists telephoneNumber] && $telephoneNumber eq "")} {
log local0. "Error: telephoneNumber variable is empty; no OTP sent for $telephoneNumber."
return
}

set rpc_handle [ILX::init ilxplugin_gov_uk extension_gov_uk]
log local0.info "RPC Handle: $rpc_handle"
if {[ catch { ILX::call $rpc_handle sendOTP $generatedOTP $telephoneNumber } result ] } {
log local0. "sendOTP failed for telephoneNumber: $telephoneNumber, ILX failure: $result"
return
}

log local0. "gov.uk status for user $username ($telephoneNumber): $result"
ACCESS::session data set session.custom.govuk.status $result
}
}

// Import the f5-nodejs module.
var f5 = require('f5-nodejs');

var templateId = 'x'; // Your Template ID

var NotifyClient = require('notifications-node-client').NotifyClient;
var notifyClient = new NotifyClient(apiKey);

ilx.addMethod('sendOTP', function(req, res) {
var generatedOTP = req.params()[0];
var phoneNumber = req.params()[1];
var personalisation = { 'passcode': generatedOTP };
var reference = null;

notifyClient.sendSms(templateId, phoneNumber, {personalisation: personalisation,reference: reference})
.then(response => console.log(response))
.catch(err => console.error(err));
//.then((response) => {return res.reply(response);});
//.catch((response) => {return res.reply(response);});
});

// Start listening for ILX::call and ILX::notify events.
ilx.listen();
