Is it possible to pass a document when calling a pipeline from a URL?

[acesario]

I’m able to call a pipeline successfull from a url thanks to all the good information here on community. Posts like Providing Authentication for Triggered Tasks by passing credentials via https request - #4 by ssanik... where very helpful.

What i’m wondering now is if (and how) I can pass a json document output from another system, directly to the pipeline as part of the execution?

If not, what design patterns have you used when trying to pass data, and execute a pipeline externally?

Hi. Have you tried this?

1. Exactly ONE open input view on the pipeline - this is where the passed data will land
2. Pass the json doc in the body of the call to the URL
3. Use REST POST, not GET

@jcampion, thanks for your response. This was really helpful and helped me to resolve this issue.

My pipeline is now setup with an open mapper, simply mapping $ to $input.
I tried your suggestion from postman, where a GET works,with no payload. My pipeline is setup with an open mapper, simply mapping $ to $input.

Trying to add a json body to and using POST resulted in a 500 error at first, but the good news is that the notification from the pipeline clued me into my mistake (exactly as you had directed me):

The state of pipeline [AC105 TEST inbound call]…] in organization … has changed to Failed.

Pipeline has no unlinked input views, but there is input data
Resolution:
Change the pipeline to have an unlinked input view or use a GET request
Reason:
An unlinked input view is required when using POST with a triggered task

@acesario - glad you were able to get it to work. Yay!
