Modeling -> Mixamo auto rigging -> UE4 retargeting

In general, there are 3 ways we can work with the Blender-UE4 pipeline:

 

1	Model character	Export model	Upload to Mixamo for auto rigging	Export FBX -> Import to UE4 -> Retarget Anim
2	Download default UE4 Character blender file	Update mesh	Adjust rigging
3	Model character	Custom rig (match the bone hierarchy with UE4 mannequin)

If you want to minimize the amount of headache and jump to UE4 programming ASAP, method 1 is your friend. (The tradeoff is that you wouldn't have custom character animation.)

This post helped me a lot. At first I wasn't able to get the mapping work, the key is that i forgot to turn on humanoid on the original skeleton of the animation.

Technical artist talks about the Blender-UE4 flow (this is from 2015.1, many things have been changed; as you can see the settings are very very *tricky)

Add root bone to Mixamo character. This might not be necessary since we can leave the root selection box to 'None'.
