PayPal Subscription IPN custom_id?

[Mynight]

I set up a subscription button that used a custom_id generated on my end to track when a payment came through to add to the database. It was the case that the custom_id could be grabbed from the IPN notification using "$_POST["rp_invoice_id"]".

However a few days after confirming it was working on the live account it suddenly stopped sending the custom_id back in the IPN messages but still shows it as the "Custom ID" in the subscription details on the main PayPal website. Doesn't show in IPN sent messages :/

Code Below, If you need any more information I'm happy to provide it.

<script src="https://www.paypal.com/sdk/js?client-id=AURxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx&vault=tru..." data-sdk-integration-source="button-factory"></script>

<script>

paypal.Buttons({
style: {
shape: 'pill',
color: 'black',
layout: 'vertical',
label: 'subscribe',

},
createSubscription: function(data, actions) {
return actions.subscription.create({
'plan_id': 'P-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
'custom_id': "" + params.get('bearer') + "", //Where I set the custom ID to be returned in IPN.
"application_context" : {
"shipping_preference":"NO_SHIPPING"
}
});
},
onApprove: function(data, actions) {
document.getElementById("payment-created").style.display="block";
}
}).render('#paypal-button-container');
</script>

I really hope someone has an answer as to how I'm being an idiot .

Sample IPN messages here suggest rp_invoice_id isn't included in the Payment Made notification. I can't see any official documentation to back that up though.

You’re quite right rp_invoice_id doesn’t appear to show up in the official documentation however when using the custom_id field it would be returned in the ipn under rp_invoice_id.

Honestly most confusing documentation I’ve come across yet .

Unfortunately it's not appearing within any of the messages, I've tried profile creation, payment, recurring payment, profile cancelled and payment reversed.

None of them contain a custom nor rp_invoice_id. Custom_id shows on paypals side but is never sent back.

I'll have a look see if I can grab it that way instead. I had hoped to keep it all server side obviously to stop anyone being a pest. Guess the confirmation is still separate from front end.

Thanks for your time!

Looks like I can get it done via webhooks.

In PayPal’s infinite wisdom they culled the custom_id tag returning in the IPN as it was apparently enabled by mistake.....

Thanks for the help @touch .
