Integrating APIGEE layer API with APPIAN

I think this part of the Appian documentation should get you quickly up to speed.

docs.appian.com/.../Integration_Tutorial.html

HI Stefan ,

We need your help we tried the integration for API using GET method but we do not have option to pass the request body json which i have shared earlier in the code section.

What else can we do to get the output response for the API integration.

We got the following error:

Value

• Dictionary
  • successfalse(Boolean)
  • resultHttpResponse
    • statusLine"HTTP/1.1 500 Internal Server Error"(Text)
    • statusCode500(Number (Integer))
    • headersDictionary

    • bodyDictionary
      • faultDictionary
        • faultstring"Failed to remove variable target.url in KeyValueMapStepDefinition getTargetURL"(Text)
        • detailDictionary
          • errorcode"steps.keyvaluemapoperations.RemoveVariableFailed"(Text)
  • errorIntegrationError

    • detail"HTTP/1.1 500 Internal Server Error"(Text)
  • connectedSystemnull(Connected System)

Failed to remove variable target.url in KeyValueMapStepDefinition getTargetURL

Thanks ,Please guide us for this!

In general a HTTP GET does not contain a body. You will need to do a POST.

HI Stefan,

We done post we are getting same internal error 500!

Thanks

OK. Then you will need to find out what this error message actually means. This seems to be an internal API. I would try to contact the development team.

Hello sunus,

are all ports open, firewalls fine ? sounds a bit your API and Appian are kind of not available for each other.
Can you reach you api in your browser?

Kind regards,
Richard

HI Richard,

I have tried same API as get method using postman, i could connect it and get response,

Only through Appian am getting above response as ERROR when i used same URL as post method.

Please guide us for this issue! What is the possible resolution for this?

Thanks

Hi Stefan,

Yes please contact the team and let us know how we can use a get method in Appian with input Json for the request body.

thanks

Can you somehow share the configuration in Postman and the one in Appian?

Can you somehow share the configuration in Postman and the one in Appian?

Hi Stefan,

I can share postman collection as code snippet and i will share appian setting as screen shot.

Thanks

Sunu Sam

Hi Stefan ,

Below reply I have shared the screen shot and postman collection, please take look and help us if possible.

thanks & regards

Hi Stefan,

uploaded collection in text format also.

Hm ... the URLs you use in Appian all go to honeywell.com. That in Postman do not.

You try to do a HTTP GET and include a HTTP body in Postman. That will not work.

In Appian you try to do a proper HTTP GET putting the parameters into the URL.

Again, did you try to contact the Honeywell internal team developing this API? They should be able to help you.

Hi Stefan,

We have already tried passing input parameters as query parameters, still we did not get proper  response.

Can we have the Appian development team reply to our query??

Thanks

Hi Stefan,

Post method worked for us, internally from apigee we changed get to POST and it started working ....Thanks for the help.

Thanks
