Sending Body to ARIBA with put method in ABAP

[ramsthota1986]

Hi Gurus,

I'm new to ABAP world, the requirement I have here is to consume data from ARIBA using Procurement API. Somehow I managed to test the whole process using Postman, But unfortunately I don't have any idea how to do the same using ABAP completely. Below are the activities I did in Postman.

1. Created a Post method in Postman to get access token - Success

2. Created a Post method to create a Template(Requisitions) in Postman Postman by sending the stricture as Body - Success

3. Created a Post method to get refresh Token in Postman Postman - Success

4. Created a Get method to get the template that I have created in point 2 in postman - Success

5. Created a Get method to get the actual data in postman - Success

I'm stuck at point no 2 in ABAP program, Any help is much appreciated. Belo is the body I'm trying to send it ARIBA

Regards,

Rambabu

Hi Rambau,

in general the way to consume services via HTTP in SAP BTP ABAP Environment is to use the HTTP client API CL_WEB_HTTP_CLIENT. There are different ways to instantiate it with the correct configuration, which are described here.
Constructing a request body can be done in different ways, but all of them involve the HTTP request, which you can get from your client using if_web_http_client~get_http_request( 😞

DATA(lo_client) = cl_web_http_client_manager=>create_by_http_destination( lo_dest ).
DATA(lo_request) = lo_client->get_http_request(  ).

On that HTTP request you can then use setter methods to set the body of the request:

lo_request->set_text( '{"a": "b"}' ).

To convert ABAP structures to JSON, you can e.g. use /UI2/CL_JSON as described in this blog. The result can then be used as the body of the HTTP request.
Finally the request can be sent:

DATA(lo_response) = lo_client->execute( if_web_http_client=>post ).

Hope this helps.
