Call API returns code 500

[hagit]

Hello experts,

I try to access a service via ABAP code. The status code which is returned is 500 . The error message is: 'The message with Action '' can not be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver.  Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).'

My code is

REPORT ztry.
DATA: im_url TYPE string
     ,lo_client TYPE REF TO if_http_client
     ,lv_send2url_xstring   TYPE xstring
     ,lv_send2url_string TYPE string

Do you know what is the problem?

 Thanks in advanced

Hi hagit

i see nobody picked this up, so let me try to help you. Obviously you know that the code miss an endif AND there is no output of any kind as the code is uploaded to an abap system. My idea is that, good you reached the soap url with correct login and password but what ever soap you are contacting has some format (at least) requirement in the payload that you are not passing through your code. hope this helps!

Before coding in ABAP, test your request via a dedicated software like Postman. Does it work?

[hagit]

@Sandra_Rossi  thankyou for your answer. I will try and let you know the results.

[hagit]

@amontella96 Thankyou for your comment. The owner of the service confirmed that the XML is valid.

[hagit]

@Sandra_Rossi the problem was solved. See Ryan-Crosby's answer. Thankyou

[hagit]

@amontella96 You was right that I did not transfer one requirement to service. See Ryan-Crosby's answer. Thank you for your help

Sounds like you are missing a SOAPAction header, so the receiving system is unable to identify which action to take.

@Ryan-Crosby Thank you for your answer. You are right. I add SoapAction and got status code 200 (success).

@Sandra_Rossi  thankyou for your answer.

I will try and let you know the results.
