Link Enterprise BAPI Web Services
Link Enterprise provides two end points to access SAP BAPI's. Using the GET request on the "any" endpoint we can retrieve what data is available to the developer. Link Enterprise BAPI web services use basic authorization with a default username: admin, and a default password: admin. Ensure SSL cert validation is disabled prior to accessing the web services.
The following examples can be imported into Insomnia Rest Client via this link: https://gimmal.box.com/s/em0ckv2zarcai15cr5az6rewxvfw18p5
For example using a get request, https://localhost:82/bapi/any?bapi=BAPI_INCOMINGINVOICE_CREATE would return the following data below:
https://jsoneditoronline.org/#left=cloud.b9e0a63872034234850ac9de5709b564
We can use this response to learn what all the available fields/data are available in that particular bapi.
To send data to BAPI_INCOMINGINVOICE_CREATE we would send a post request to https://localhost:82/bapi/any using the json body included in this link:
https://jsoneditoronline.org/#left=cloud.dbd7f72e2ade41eab9301c17081b2a04
You should see the following json response here
https://jsoneditoronline.org/#left=cloud.73c35d070cb546f683dc05e82865cac1
Notice in the export parameters the response given from the BAPI that was executed
Another example is given here with BAPI_PO_CHANGE using post.
https://jsoneditoronline.org/#left=cloud.b9a0aeb968344aeb94b1153ca69b1959
and it's corresponding response,
https://jsoneditoronline.org/#left=cloud.d6ef93f919e443d7a8153c1fd6b856ec
Common tables to look at for response from SAP are the return table, and the export parameters.
