# Issue with RingCentral Fax API using MBS Plugin – JSON Response Received, but Fax Not Processed **URL:** \ **Category:** MBS Plugins\ **Created:** [October 18, 2024, 1:24pm UTC](https://the.fmsoup.org/t/issue-with-ringcentral-fax-api-using-mbs-plugin-json-response-received-but-fax-not-processed/4364 "2024-10-18T13:24:52Z")\ **Posts on this page:** 15\ **Page:** 1

I'm using the MBS Plugin to make a call to the RingCentral Fax API. While I am getting a valid JSON response back, the fax is not being processed by RingCentral. However, when I run the same API call through Terminal or via a script (without using the MBS Plugin), the fax gets processed successfully. Has anyone experienced a similar issue with the MBS Plugin when interacting with RingCentral? Any suggestions on what could be causing this or how to troubleshoot? ---

Can you log the call with Terminal with headers for inspection? And also get debug messages from our plugin to compare? Probably some little header setting is missing. ---

Well, you do a GET with the plugin. I don't see you use PostFields or form functions. ```auto MBS( "CURL.FormAddKeyValue"; $curl; "to"; "+16502413764" ) MBS( "CURL.FormAddKeyValue"; $curl; "faxResolution"; "High" ) MBS( "CURL.FormAddKeyValue"; $curl; "coverPageText"; "Please see the attached document." ) MBS( "CURL.FormFinish"; $curl ) ``` So you'd use [CURL.FormAddKeyValue](https://www.mbsplugins.eu/CURLFormAddKeyValue.shtml) and [CURL.FormFinish](https://www.mbsplugins.eu/CURLFormFinish.shtml) functions to build the form values before the [CURL.Perform](https://www.mbsplugins.eu/CURLPerform.shtml) call. ---

What does CURLDebugMessages say? Do all functions return OK? Did you do a trace log? And after CURL.Perform, you could write CURL.GetFormData to a text file and see if the values and the PDF are included. (And maybe provide me as download to inspect?) ---

Well, you can send me a test database with the script to try here. Or you [Trace](https://www.mbsplugins.eu/component_Trace.shtml) function to have it log all calls to a log file. ```auto Content-Length: 477 ``` this may point to the file not being included. e.g. if the fee path is not right. I usually put in my server URL in ```auto https://www.monkeybreadsoftware.de/filemaker/echo.cgi ``` which will return what is output. Also you could of course try a current version of the plugin in case there was a bug last year. ---
