Can Bing Ads Offline Conversions be achieved in a REST API way with the Curl command on Linux? Or, is there a way to understand the SOAP API process with Curl so that I can understand the lower-level HTTP calls it makes and can parse the SOAP XML response?

GetUser API calls

I'll start out with using curl command on Linux for accessing BingAds API/ to understand the same process of SOAP API process with Curl/ lower-level HTTP call it makes...

Consider these basic examples:

• https://learn.microsoft.com/en-us/advertising/guides/authentication-oauth-quick-start?view=bingads-13
• see schema of GetUser API here: https://learn.microsoft.com/en-us/advertising/customer-management-service/getuser?view=bingads-13

accessToken=<fill in..>
developerToken=<fill in..>

soapRequest='<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:v13="https://bingads.microsoft.com/Customer/v13"><soapenv:Header><v13:DeveloperToken>'$developerToken'</v13:DeveloperToken><v13:AuthenticationToken>'$accessToken'</v13:AuthenticationToken></soapenv:Header><soapenv:Body><v13:GetUserRequest><v13:UserId xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true" /></v13:GetUserRequest></soapenv:Body></soapenv:Envelope>'

echo "soapRequest: $soapRequest"

soapResponse=$(curl -X POST -H "Content-Type: text/xml" -H "SOAPAction: GetUser" -d "$soapRequest" https://clientcenter.api.bingads.microsoft.com/Api/CustomerManagement/v13/CustomerManagementService.svc)

echo "soapRequest: $soapResponse"

Bing Ads Offline Conversions API calls

I can point you to the following links, which you may try out using above method.

• https://learn.microsoft.com/en-us/advertising/campaign-management-service/applyofflineconversions?view=bingads-13
• https://learn.microsoft.com/en-us/advertising/guides/code-example-offline-conversions?view=bingads-13
• https://learn.microsoft.com/en-us/advertising/bulk-service/offline-conversion?view=bingads-13

However, other than for the purpose of understanding SOAP API calls to BingAds, I would recommend against using curl for your automation. Instead, use C#/Java/Php/Python APIs links. C# in .net core works executes well in Linux platform.
