Consume a web service

How can I consume a web service after the user has validated a customer invoice?

consume a webservice? What do you mean?

Hello,
I mean call a web service. I’m already doing it using a trigger for bill_validate. Thank you.

Maybe a webhook is what you need?

Hello,
I am handling it with a trigger, but if you know how to do it with a webhook, I would appreciate if you could tell me how to solve it that way.
Thanks.

I do not use it, but I would start here:

Home, Setup, Module/applications, search for webhook.
