Error 400051 : "No match in backends for the given tenant id", when attempting to create a service via Campaign API

[hareldit]

I'm trying to create a test service, using the example request in the docs here: https://docs.adobe.com/content/help/en/campaign-standard/using/working-with-apis/managing-services-a.... 

Using postman, I'm sending a post to (changed the org ids etc.): 

https://mc.adobe.io/1234567890ABCDEF@AdobeOrg/campaign/profileAndServices/service/

with a json body: 

{
"label": "Test Service",
"messageType": "email",
"name": "test_service",
"start": "2020-07-28"
}

I've got the right headers of the authorization and x-api-key etc. 

However, I'm getting back a 400 error: 

{"error_code":"400051","message":"No match in backends for the given tenant id."}

What does that mean? How can I approach this?

org ID would be your ACS url that you use to access and login to the application.

E.g. https://ABC.campaign.adobe.com/ 
https://ABC-mkt-stage1.campaign.adobe.com/

The values of ABC must be provided in place of Org ID in post request.

You org ID would be:- 

https://mc.adobe.io/ABC/campaign/profileAndServices/service/

i created the Adobe I/O integration and generated the public/private keys. But when I try to test REST api  I get the error - No match in backends for the given tenant id.

My question is do we need to configure the campaign standard instance with the keys generated by Adobe IO?
