hmm...another option would be n8n (https://n8n.io/). comes as a docker container. there you can build your customized pipelines. check out the available integrations (https://n8n.io/integrations/). basically, what you want is a webhook, post your JSON to that webhook, and a second node that does the work with that JSON as an input.

very flexible and is set up in less than an hour.
