Hi All,

Can anyone advice If it is possible to send a delegate execution(or workflow execution Object) over http.ie from one microservice to another (POST methods only).

Hi Albin,

This is not possible as these objects are not easily serializable in any format. If you expand on your use case, we may find another solution.

Thanks @thorben for your response.
So as a work around I have decided to use the microservices as independant entities.
But the current issue am facing is that :
My workflow has 3 service tasks(all of them are microservices implemented using connector variables)
I want to take the response of the 1st service task and give it along with the payload to the second ,so on and so forth.
Would that be possible…Could you please advice.

Thanks and Regards,
Albin Chandy

You can store the result of the connector call in a process variable and then use the variable to create the payload for the next service call.

By the way, the external task feature is another approach to orchestrating microservices, which may be of interest.
