The preferred method for supply partners not able to use the SDK is to access MobileFuse demand via our OpenRTB API. We have implemented a subset of the OpenRTB 2.5 specification, which is detailed in this document. At this time, only mobile app and CTV requests are supported.


MFX has data centers in us-west, us-east, and eu-west, and our endpoint will choose the endpoint with the lowest latency from the originating location. HTTPS is supported as well if necessary. Endpoints will look like below, but you will receive the exact endpoint from your account manager, which will change depending on whether you are passing your tagids or MobileFuse’s.[PUBLISHER_ID]&tagid_src=[TAGID_SOURCE]
