|format||The format of the table (JSON or CSV)|
|prefix||A prefix to be added to lookup value names|
|sufffix||A suffix to be added to lookup value name|
|key||The name of the frame attribute used to in the lookup|

This function searches //url// for any cases where //rkey// matches the value of //key// in our frame.

This is often used to load product details or other useful tabular data into a capture.

This layer may cause [[frame looping|frame looping]].

===Example===

If the frame contains the following attributes...

^Attribute^Value^
|ProductSKU|AR97B|
|StartTime|10:00AM|
|EndTime|11:00AM|

and we have the following table...

^SKU^Weight^Height^Width^Depth^
|AR97A|500|100|100|100|
|AR97B|800|120|120|120|
|AR44X|1200|1200|120|120|

<code javascript>
{
   "type": "lookup",
   "url": "https://mylookuptable",
   "key": "ProductSKU",
   "rkey" : "SKU",
   "prefix": "Product"
}
</code>

The final results attributes will look like...

^Attribute^Value^
|ProductSKU|AR97B|
|StartTime|10:00AM|
|EndTime|11:00AM|
|ProductWidth|120|
|ProductHeight|120|
|ProductDepth|120|
