<p>Hi Andrew,</p>
<p>Yes, the "Multiple Input" input type should do the trick. After that input parameter you'd normally have to merge all input files/layers into one. The "Merge vector layers" transformer seems to be one of the very few (or the only) algorithm that seems to accept multi-layer input.</p>

<p>Of course the "Merge vector layers" algorithm expects the layer to have the same structure, otherwise you'll have some really funny and unpredictable results.</p>
<p>Greetings and hope this helps,</p>
<p>Andreas</p>

<div dir="ltr">Hi All,
<div> </div>
<div>Could any provide some advice as I am new to this and need some guidance please.</div>
<div> </div>
<div>My model needs to consume data from MULTIPLE Esri rest layers. I can do this for on a 1:1 basis where I manually add 1 input vector layer per esri rest layer. But that's not great. This model is not easily reusable, as the number of layers always varies.</div>
<div> </div>
<div>Q1: The merge processor takes in a multi-layers on a single input - but I can't see how this is done in a model. Can anyone please explain?</div>
<div> </div>
<div>Q2: Is is possible for me to write a python processor that doesn't require any project layers as input, it can create the layers itself (in code/config) and feed them into the merge processor and output the single merged layer?</div>
<div> </div>
<div>Thanks in advance</div>
<div>Andrew</div>
