DLR not received

[eshetua]

Hello!

We use the REST API to send messages and request level 3 DLR with all the necessary configs. It looks like DLR messages are not properly thrown or show as SMS-MO in the messages log (excerpt below). The messages send to the user phone properly ... it's just that further DLR statuses are not sent back to our callback URL.

We use 1 for dlr_msgid since one is hex and another is decimal for the message ids. We have also tried switching between data_sm and deliver_sm for dlr_pdu value inside jasmin.cfg. What are we missing and why are DLR messages show as SMS-MO?

Thanks for your help and a fantastic product!

@eshetua did you figure out a solution. tried all of the above as well and same error. The issue is that HttpApiError() is quite vague and from this line, it seems it's thrown when the dlr-url returns a status >= 400.

I have tried my dlr-url and it's returns a 200 OK with ACK/Jasmin content. Would love to hear an update if you got this working, thanks!
