Integrate WhatsApp API with SAP — Send WhatsApp Messages from SAP

Step 1: Open SCOT and Create an HTTP Node

1. Run transaction SCOT
2. Navigate to Nodes → Create
3. Enter node name ZAPTILO and description "Zaptilo WhatsApp Gateway"
4. Select node type as HTTP and continue

Step 2: Configure the HTTP Endpoint

Set the API server URL:

https://web.zaptilo.ai/api/send/template

Leave username and password blank — Zaptilo uses Bearer token authentication via theAuthorization header.

Step 3: Set Address Type and Activate Node

1. Add address type PAG (pager / SMS) with address area *
2. Set retry time period to your preferred value (e.g. 30 minutes)
3. Tick HTTP node is active and save

Step 4: SICF Handler Configuration

1. Run transaction SICF
2. Select default_host → create a new sub-element
3. Add the following handlers:
   • CL_HTTP_EXT_FORMTORFC
   • CL_HTTP_EXT_XRFC
   • CL_XMS_HTTP_HANDLER
4. Save and activate the service

Step 5: Define a Pager Service in SA14

1. Run transaction SA14 in client 000
2. Create a new entry: Pager Service WHATSAPP, Use WhatsApp Service
3. In SPRO go to: SAP Web Application Server → Application Server → Basis Services → Address Management → Define Pager Services

Step 6: Test from SBWP

1. Run transaction SBWP (SAP Business Workplace)
2. Click New Message and compose a test message
3. Set recipient type to PAG with the phone number including country code (e.g. 919876543210)
4. Send and monitor the queue in SCOT

Sample ABAP Report

A complete standalone report that sends a WhatsApp template message:

REPORT  zsend_whatsapp.

DATA: lo_http_client TYPE REF TO if_http_client,
      lv_url         TYPE        string,
      lv_token       TYPE        string,
      lv_payload     TYPE        string,
      lv_response    TYPE        string,
      lv_status      TYPE        i.

" Configuration
lv_url   = 'https://web.zaptilo.ai/api/send/template'.
lv_token = 'YOUR_ZAPTILO_API_TOKEN'.

" Build JSON payload for the WhatsApp template
lv_payload =
  '{' &&
  '"number":"919876543210",' &&
  '"template_name":"order_confirmation",' &&
  '"language":"en",' &&
  '"body_values":["John Doe","ORD-12345"]' &&
  '}'.

" Create HTTP client
cl_http_client=>create_by_url(
  EXPORTING url    = lv_url
  IMPORTING client = lo_http_client
  EXCEPTIONS OTHERS = 1 ).

" Set request method and headers
lo_http_client->request->set_method( if_http_request=>co_request_method_post ).
lo_http_client->request->set_header_field( name = 'Content-Type'  value = 'application/json' ).
lo_http_client->request->set_header_field( name = 'Authorization' value = |Bearer { lv_token }| ).

" Set body
lo_http_client->request->set_cdata( lv_payload ).

" Send request
lo_http_client->send( EXCEPTIONS OTHERS = 1 ).
lo_http_client->receive( EXCEPTIONS OTHERS = 1 ).

" Read response
lv_status   = lo_http_client->response->get_header_field( '~status_code' ).
lv_response = lo_http_client->response->get_cdata( ).

" Close connection
lo_http_client->close( ).

" Output result
WRITE: / 'Status:', lv_status.
WRITE: / 'Response:', lv_response.

Replace YOUR_ZAPTILO_API_TOKEN with your actual token.

Reusable Function Module

Wrap the logic into a function module so it can be called from any program, BAdI, or workflow:

FUNCTION z_send_whatsapp_template.
*"----------------------------------------------------------------------
*"  IMPORTING
*"     VALUE(IV_NUMBER)        TYPE  STRING
*"     VALUE(IV_TEMPLATE_NAME) TYPE  STRING
*"     VALUE(IV_BODY_PARAMS)   TYPE  STRINGTAB
*"  EXPORTING
*"     VALUE(EV_STATUS)        TYPE  I
*"     VALUE(EV_RESPONSE)      TYPE  STRING
*"----------------------------------------------------------------------

  DATA: lo_http_client TYPE REF TO if_http_client,
        lv_payload     TYPE string,
        lv_params      TYPE string.

  " Build comma-separated body params as JSON array
  LOOP AT iv_body_params INTO DATA(lv_p).
    IF lv_params IS INITIAL.
      lv_params = |"{ lv_p }"|.
    ELSE.
      lv_params = |{ lv_params },"{ lv_p }"|.
    ENDIF.
  ENDLOOP.

  lv_payload =
    |\{| &&
    |"number":"{ iv_number }",| &&
    |"template_name":"{ iv_template_name }",| &&
    |"language":"en",| &&
    |"body_values":[{ lv_params }]| &&
    |\}|.

  cl_http_client=>create_by_url(
    EXPORTING url = 'https://web.zaptilo.ai/api/send/template'
    IMPORTING client = lo_http_client ).

  lo_http_client->request->set_method( if_http_request=>co_request_method_post ).

  lo_http_client->request->set_cdata( lv_payload ).
  lo_http_client->send( ).
  lo_http_client->receive( ).

  ev_status   = lo_http_client->response->get_header_field( '~status_code' ).
  ev_response = lo_http_client->response->get_cdata( ).
  lo_http_client->close( ).
ENDFUNCTION.
