PayPal IPN issue

[KW]

Hey team

PayPal isn’t recognizing our IPN.

SWPM generates the following code for the advanced variable field:
notify_url=https://example.com/?swpm_process_ipn=1
custom=subsc_ref=10

PayPal gives an error when trying to process the advanced variable field code:
https://example.com/?swpm_process_ipn=1%20custom%3Dsubsc_ref%3D5

They say they cannot process that. One thought that came to mind was that the %20 which is indication the space between ipn=1 and custom=subsc isn’t functioning correctly.

Would it work if I used the following code in the advanced variable field, where I replace the %20 space with a + sign? Like so:
notify_url=https://example.com/?swpm_process_ipn=1+custom=subsc_ref=10

That would create an output as follows:
https://example.com/?swpm_process_ipn=1+custom%3Dsubsc_ref%3D5

Clearly I am doing something wrong. Do I have the right solution here?

Hi, try without the + symbol as illustrated below.

notify_url=https://example.com/?swpm_process_ipn=1custom=subsc_ref=10

If the above does now work trying adding _ like this ipn=1_custom. Let me know what happens.

Thank you
