Creating a simple REST api

Scriptcase 8 Discussion
#1

Can someone please help me here. I would like to create a simple REST api, that:
Receives in x2 parameters from a 3rd party application
Once I receive these parameters I need to update and perform various tasks
Upon conclusion, I would like to let the initiating 3rd party application know the result (even the word “done”)
If there is an error, I would like to let the initiating 3rd party application know the error.

I have searched all over the net for answers, and each time I try what seems to work outside of SC, it bombs when trying in SC.

Keep in mind that SC is a php generator, so all that is done in php can be done in SC. In case of a rest-api you don’t have a form interaction. So you need to create blank applications. In rest api parameters are sent by the url as $_GET. Within scriptcase you can use the macro’s to access your database. Nothing more to it.

This is what I am doing. I am getting an error as in the end of this post.

Can you tell us how did you solve it? I am in the same case

Thanks

Hi all,
Is there a tutorial or video available that can help to get started with this. I am also interested in best practices on how to access REST API’s and use it’s data to keep an internal database uptodate.

Regards,

No, but using API’s is not out-of-the-box. Scriptcase does have something but I never looked into it as it’s related to certain api’s only. But it really is not that hard. With Curl you access the external api, and with the macro’s of scriptcase you process the response. Depending on the API you get a json encoded string that needs to be decoded. If you consume webservices like this then you can apply this in any module. If you are writing an api that will be called then this needs to be a blank application obviously. Hope this helps.
