To call external API's through ABAP
I have a requirement where in I need to call external API's through SAP to basically push and pull data.
The API's are similar to those provided by the e-commerce channels. I need to call these API's and accordingly push and pull data, such as orders created for the sellers etc.
Can you kindly provide some help as I am not sure how to call these API's. Does it only involves Call Function..? or anything else. Also, the API's would be in different languages may be in cake php so need to do the development accordingly.
Kindly share details or provide some tips regarding the approach.
