What's the difference between:
- Have someone do something
- Make someone do something
- Get someone do something.
To have someone do something means to cause someone to do something.
To make someone do something means to force someone to do something.
To get someone do something means to persuade someone or trick someone to do something.
This is what the dictionary says but I saw they're sometimes interchangeably used, so dictionary definitions are not enough.

There is a lot of nuance in the differences, as Tᴚoɯɐuo pointed out in his comment to your question. More context would really help here. By and large, these phrases can be used interchangeably, but there are also cases where the meanings are different, and in line with the dictionary definitions that you've provided. For a simple case:
These all mean roughly the same thing. In all three cases, the subject of the sentence (she) successfully directed the object (him) to clean his room. Without more context, we don't really know how they differ. We know that she provided the influence, and he obeyed and completed the task. How coercive did she have to be? We don't know. We don't even know why he complied. We only know that he did. You could infer some added meaning based on the dictionary definitions, but you could be reading something into it.
And so you begin to see that the nuance comes out largely in the context of the relationship of the two people - the one making the plea, and the one acting in response to it.
In this instance, there is an evident chain of authority. When the speaker issues her command, she expects that authority to be sufficient motivation for the driver to carry it out. It is expected of him.
Here, the appeal is made to a higher authority because the one making the plea does not have sufficient authority herself to cause the thing to happen. This would be the only appropriate choice of the three options. It can be used similarly where the person making the appeal has the authority, but does not have the ability (presently) to cause it to happen.
The last option probably has the most flexibility with it, and is most dependent on context, because it can be used in a slightly informal manner. For instance:
There's no coercion going on here. It's a natural use of the construct, and it will be a normal business transaction taking place between the woman and the plumber. Whereas:
clearly indicates that something foul is taking place. But in this case, with the additional context that's provided, all three options would work.
