How to add new attachment during a lifespan of a running workflow?

There was an error rendering this rich post.

Hi,

I was wondering if there is an option to somehow add / replace attachment during the lifespan of a workflow. I'll try to give an example :

I have created a workflow "A" that will be signing the attachment that in that "A" WF with digital signature.
For that I have an execute step which will be running some custom .exe to fulfil the signing job. The signed attachment of the job will be then stored somewhere locally in a file system.

Let's say I know it's location. How can I re attach the signed attachment the running "A" WF?

If you have a reference to the Attachment or the Workflow (from which you can get over to the Attachment) then you can use the Add Version REST API call to add the version into the workflow.

Is there a reason that you are not using the provided eSign or DocuSign integrations ?

Well, I assume it's because it costs additional funds :) Am I mistaken?

For the other modules, depends on your agreement with OT and then the signature providers.

Apart from that, there is the REST / WebService / WebReport / AnswerModule etc options depending on what you have and your skills etc.
