Address Search in Segmentation Geolocation

Dear community,

I am struggeling with the address search in segmentation for geolocation option (including clustering).

I read that there a special rfc connection is necessary - but I can't find any precise documentation (step by step) for this.

At the moment I only get "address search failed - bad request".

Has anybody a hint for this.

Thanks in advance.

Cheers,

Timo
