Make API call to 3rd party app upon successful transaction payment

I would like to offer a paid work such that upon every successful transaction payment, to send an API call to a 3rd party app to update the sales information into that app

Do private message me for details

Thank you

See NewBook PMS topic, would have everything you need on there to do yourself.

Personally i would consider that you post to api and Mark paid on success responce rather than blindly post. Or post days sales at end of day.
My topic covers both as cash sales are synced behind the scenes and room posts are posted there and then.

This topic is from scratch me learning scripts etc so should cover basics through to completion.

if you want someone to do for you post details of the api you want to post to so we can check functionality and exactly what data you want posting to it.
